Hey folks!

For anybody stumbling on this post from outside lemm.ee: I am the head admin of lemm.ee, a general purpose Lemmy instance, which recently turned 1 year old. I am writing this post to elaborate on how we approach defederation on lemm.ee.

Anybody who has been on Lemmy for a while has most likely seen several public defederation drama posts (most recently regarding lemmy.ml, but there have been many many others previously). As an admin, I have probably seen far more than what is visible publicly, as I regularly receive private messages on the topic, ranging from polite questions about federation, to outright demands that I immediately defederate, and even to threats and personal attacks over the fact that I have not defederated some particular instance. It is definitely a topic that will keep coming up for as long as Lemmy exists, which is why I feel it would be useful to condense my current thoughts about it in a single place.

Note that while I strongly believe everything this post contains, it is definitely a subjective topic, and there is no single right answer here. Other instances have completely different approaches to federation compared to lemm.ee, and that’s of course totally fine. The beauty of Lemmy is that everybody can choose their home instance, and in fact, everybody is free to spin up their own instance and run it however they feel is best. For an absurd example, if you want to create an instance which defederates any instance with an “L” in their name, then nobody can stop you!

Quick intro to the lemm.ee federation policy

Very shortly after creating lemm.ee, I wrote down a federation policy, which basically boils down to “we treat defederation as an absolute last resort, and we do not use it as a generic way to curate content for lemm.ee users”. This policy can always be found in the sidebar of the lemm.ee front page.

In practice, this has meant that we have had extremely few defederations, and that we mostly solve problems with other means. I am very happy with the results, as it means that lemm.ee has become a great entry point into the Lemmy network, with very few artifical limitations on who our users are allowed to interact with.

The benefits of federation

I hope that this part of the post is very uncontroversial, but I firmly believe that federation is the absolute strongest feature of Lemmy. While we all know that the concept of federation can cause confusion for new users, this is usually overcome extremely quickly (for example, using the common e-mail providers analogy to explain Lemmy instances). To me, it’s completely clear that the benefits of federation far outweigh the downsides.

For example, by splitting the Lemmy network between thousands of independent nodes, we ensure that:

1. Any single entity is not a single point of failure for the whole network. Even if the biggest instance goes down tomorrow, their content will still be accessible through all the other federated instances.
2. The maximum impact of admins is limited to their own instance. As a lemm.ee admin, I can ban a remote user from posting on lemm.ee, but I can’t completely ban them from the entire network.
3. Private user data (such as ip addresses, e-mails, etc) are never shared between instances. No single malicious instance can harvest user data for the entire network, and extremely privacy sensitive users can always spin up their own instance if they don’t want to put their trust in any existing admins.

One thing which is probably important to note here is that I tend to view Lemmy instances as infrastructure, rather than as communities. I know that there are alternative approaches, as quite a few large instances are in fact run as mega-communities, but that’s not the approach I take with lemm.ee, because I feel like such an approach encourages centralization and negates some of the benefits of federation (if all communities related to one topic condense on a single instance, then that instance does effectively become a single point of failure for a large number of users).

In general, I feel like it should be a goal to encourage and cultivate decentralizing the network through federation as much as is practical, in order to maximize the above benefits.

The downsides of dedeferation

Conversely, defederation has a lot of downsides.

1. It obviously negates all the benefits of federation mentioned above. Every time two instances defederate, the Lemmy network becomes less redundant, some communities become a bit more centralized, and the danger of malicious admins for those communities becomes much greater.
2. There is a lot of collateral damage. The most common reason I have personally seen for defederation demands is related to moderation of either a single user, or a handful of users. For example, a lemm.ee user gets into some heated arguments with people from an instance with hundreds of active users, and then links this heated thread to me as proof that the instance should be immediately defederated. However, in this situation, there are hundreds of other users who were not even involved (or even aware of) the thread in question. By defederating, I would be making a decision to cut off every single lemm.ee user from every single one of those hundreds of innocent remote users.
3. Ironically, defederation actually makes moderation more difficult. It was recently pointed out to me by a user on another instance that they are afraid they can’t effectively moderate communities on lemm.ee, because their instance has defederated several other instances, which means they would not be able to see posts from those instances on lemm.ee communities.
4. It is extremely easy for malicious actors to abuse. In the year I’ve been on Lemmy, I have already seen two separate cases of users creating accounts on another instance and posting garbage, and then going back to their home instance and demanding their admins defederate over the content they themselves created. Basically, if an instance is known to use defederation as a tool to punish misbehaving users on other instances, then it’s actually quite easy for users to manipulate the situation to a place where admins have no alternative except to defederate.

It seems to me that a lot of users don’t think of such downsides when demanding defederation, or they just don’t consider them as important enough. In my opinion, these are all significant issues. I do not want to end up in a fragmented Lemmy network, where users are required to have accounts on 5 different instances in order to be able to access all their communities.

What’s the alternative to defederation? Should Lemmy become some kind of unmoderated free speech abolutism platform?

I want to be very clear that I do NOT believe in unmoderated social networks. Communities should always be free to set and enforce rules which foster healthy discussions. On top of that, instances should always be free to set and enforce rules for all of their users and communities.

In the case of lemm.ee, we have some instance-wide rules, and we will enforce them on all lemm.ee users, as well as all remote users participating in communities hosted on lemm.ee. For example, we never want to offer a platform for bigotry, so we regularly issue permanent bans for users who want to abuse lemm.ee to spread such hate. In practice, site bans have been extremely effective at getting rid of awful users, whether they are remote or local.

On top of site bans, Lemmy admins also have the option of removing entire remote communities. There are certainly cases where a community might be allowed on instance A, but not instance B - rather than defederating (and potentially cutting off a lot of innocent unrelated users), instance A can just “defederate” a single community.

Finally, a lot of issues can be solved through simple communication between instance admins. Often having a discussion with another admin results in pretty clear alignment over whether some user is problematic, and the user will end up being banned on their home instance.

Being one of the most openly federated large instances with such an approach, we have discovered several things:

1. If we were to defederate over every rule breaking user or community on the Lemmy network, we would not be federated with any of the large instances at this point
2. In the vast majority of cases, remote users who have broken lemm.ee rules have ended up banned on their home instance anyway - there is very little additional moderation workload for our admins from being widely federated
3. If a user truly wants to spread some kind of hate, defederation wouldn’t stop them anyway, as they will just create accounts on any instance which they want to “attack”

The longer I run lemm.ee, the more sure I become that in the vast majority of cases of abusive users, the best approach is to simply hand out site bans.

When is defederation the only option?

Having said all of the above, I still believe that there a few cases when defederation is the best option:

1. When an instance is abusing the Lemmy network - generating spam, advertising, illegal content, etc - either deliberately, or through inactive admins (this has been the most common reason for lemm.ee to defederate any instance in the past)
2. When an instance is just causing too much moderation workload. So far, we haven’t experienced this yet on lemm.ee, but I can’t rule out that it could happen in the future.

Conclusion

I hope this post helps clarify my stance on defederation. Like I said in the beginning, I realize a lot of this is subjective, and there are no right or wrong answers - this is just the way we have been (and will be) doing things on lemm.ee. I intend to save this post and link it in the future when people bring up defederation requests. If you feel like I didn’t address something important, please feel free to raise it in the comments!

Hey folks

Just a heads up that I will be doing some minor database maintenance shortly. I expect the downtime to last <5 minutes.

Have a nice day!

Update: maintenance is complete!

Hey, folks!

Today, we can celebrate the first anniversary of the creation of lemm.ee! I thought it would be cool to write down how lemm.ee was born, as well as collect some stats about our first year. Here goes!

A quick recap of the beginning of this instance

As probably many others here, I discovered Lemmy early last summer. I had been aware of the Fediverse previously, and always thought it was an amazing concept, but I had never been super interested in Twitter-style social networks. When I found out that Lemmy combined all the great parts of federation with the best parts of link aggregation, I knew that I had to join immediately.

As I was trying to find an instance to make my account on, I realized that most instances were struggling to keep up with a massive influx of new users. At the time, there was a big explosion in Lemmy user numbers, and the network wasn’t fully ready for it. I have some experience with building software for scale, so it felt natural to set up a new instance and try to help with spreading out the load. I got to work in the evening of the 8th of June, 2023, and I was actually so excited about everything, that I completely skipped sleep that night. By the morning of the 9th of June, lemm.ee was online.

From the very beginning, I always intended for lemm.ee to be a welcoming, reliable, and stable gateway into the Lemmy network. I wrote a welcome post on lemm.ee, which most of you have probably seen, as well as a comment on lemmy.ml inviting new users to lemm.ee (lemmy.ml, as many instances, was extremely overloaded at the time).

We started growing extremely quickly. Thousands of users joined lemm.ee over the first few months. Even during the biggest waves of new users, we never closed our sign-ups. The first month or two were definitely very stressful in terms of just trying to deal with the load, but overall, I think I managed to deal with it well enough, and lemm.ee has been running more or less smoothly (with a few exceptions) ever since.

Some stats about the first year

I promised to collect some statistics about lemm.ee so far. This is what I’ve come up with:

Usage

Overall, lemm.ee has 28,715 registered users. Of course, it’s easy to create an account, and most of these are probably inactive at this point, but it’s still a ridiculous amount.

Of all the registered users, 7903 have made at least one post or comment.

7373 users have never made any posts or comments, but have still been voting. This means that out of users who actually interact on lemm.ee, more than half generate content (through their comments and posts) - this is way more than I expected!

Meanwhile, we also have 13,439 users who have never made a single comment, post or vote. I guess most of these are people who just signed up and never got into Lemmy, but I’m sure there are quite a few hardcore lurkers among this group as well.

As for communities, our users have created 1430 of them. Most of these have not (yet) taken off, as only 491 of these communities have at least one comment in them. In general I am happy to see some great communities appearing on lemm.ee - my hope is that we can spread awesome communities out quite evenly on the network, so that in the end, no instance becomes a single point of failure for Lemmy.

Judging by posts and comments made by lemm.ee users, I feel like we’re definitely on the right track: our users have made 20,898 posts in local communities, and 30,847 posts in communities hosted on other instances. The situation is even better for comments, where lemm.ee users have written 42,785 comments in local communities, and a whopping 569,730 comments on remote communities! This means that lemm.ee is not just its own little closed pocket in the Fediverse, but indeed a proper gateway to the Lemmy network, which is exactly what I always hoped it would be.

Note about comment and post counts: I realize the numbers above don’t match the stats about posts and comments on our front page, I’m guessing something is out of sync there, but the stats I am sharing here are based on actual fresh data, counted directly in our database today.

Lemmy (and lemm.ee) would be quite useless without its users, so a big thanks to all of you for using lemm.ee!

Administration

We have a really awesome volunteer admin team, with admins putting in countless hours of their free time to help weed out bad actors. A lot of the work our admins do is completely invisible to most users. I think the admin team does not really get enough recognition, and in fact in many cases, they actually get some undeserved abuse thrown at them.

I am personally very grateful for everybody who has stepped up to be a part of the team, and I think all lemm.ee users benefit from their work every day. In the past year, our admins have handled 12,329 reports from users. While most reports aren’t too bad, and don’t require harsh action, there is still a significant amount of these reports which contain the absolute worst content which you can find on Lemmy - hate speech, bigotry, gore, even illegal content. Our admins are constantly going through every single report they receive, to ensure that mods are getting admin-level support where needed, and to ensure that malicious users in general can’t use lemm.ee to spread garbage into the Lemmy network.

In terms of admin actions, I think the most interesting statistic might be amount of users banned by lemm.ee admins, grouped by their home instance. I will list the top 10 instances here:

• kbin.social: 581
• lemm.ee: 355
• lemmy.world: 31
• sh.itjust.works: 29
• m.mxin.moe: 28
• discuss.tchncs.de: 26
• kbin.chat: 22
• mastodon.social: 19
• lemmy.ca: 18
• fedia.io: 16

As you can see, with the exception of kbin.social, the vast majority of our instance bans are for our own users. Most of the big instances are actually very good at banning their own abusive users, and once they are banned on their own instance, our admins don’t really need to worry about them, as they have no way to log in at that point. kbin.social is a bit of a special case - they either don’t give out a lot of bans, or those bans just don’t federate to Lemmy properly, and for some reason, a lot of advertisers sign up on that instance all the time.

Financials

I have received some questions every now and then about how much it costs to run lemm.ee. While you can always get a sense for the predicted monthly costs for the current month on https://status.lemm.ee, I thought I might include a full breakdown of our costs for the first year here.

Here are all of our costs for the past year, grouped by service:

• Postmark: 177.06€
• Cloudflare: 222.28€
• DigitalOcean: 1744.27€
• Hetzner: 510.20€ (lemm.ee migrated from DigitalOcean to Hetzner several months ago)
• Backblaze: 3.78€ (we’ve been using Backblaze B2 for a few months now, it’s incredibly cheap)
• Domain registration: 100.70€ (paid for the next 10 years!)

We are currently completely funded by lemm.ee users!

There is a small minority of users who are shouldering the entire cost of lemm.ee for all of us. I am extremely grateful that others find Lemmy useful enough that they have put their own money into ensuring financial stability for lemm.ee.

We currently have 49 active sponsors on GitHub, and 7 active supporters on Ko-Fi. In addition, there have been 62 more sponsors on GitHub over the past year, as well as 49 additional supporters on Ko-Fi. This means that in total, 167 users have supported lemm.ee financially. This has completely exceeded all my expectations, I really think it’s incredible. A huge thanks on behalf of myself (and I think I can speak for all other lemm.ee users here as well) to all the supporters!

Conclusion

Running lemm.ee has certainly been a rollercoaster in many ways. There are a lot more things which happened during the first year that I could write about here. On the other hand, this post is already quite long, and a lot of the things which happened are probably best forgotten about anyway, so I think I should wrap up here 😅.

At its core, Lemmy is really an amazing piece of software. It’s helping real humans connect on the internet, without any corporate bullshit. I am very happy to be here with all of you, thank you for joining lemm.ee for its first year, and I hope you’ll join me here again when I write this post in another year from now!

Hey all!

Upcoming lemm.ee cakeday

Can you believe that lemm.ee is almost 1 year old? In just a couple of weeks (specifically, on the 9th of June), we will be able to celebrate our first instance cakeday.

I am thinking of compiling some stats about how lemm.ee has been used in its first year, if you have any specific stats in particular you would like to see, feel free to comment below. I will try to accommodate any ideas as I start gathering this info!

Infrastructure updates

A few weeks ago, I posted about plans to make some changes to our infrastructure in order to deal with different intermittent networking issues.. It took a bit longer than I hoped (just did not manage to get enough free time between then and now), but I am happy to report that this work has now been completed! Additionally, I have decommissioned our stand-alone pict-rs server.

With the two changes mentioned above, I believe lemm.ee should now be much more resilient going forwad, and I expect a significantly lower rate of infrastructure-related issues for the rest of the year!

I'll leave a tehcnical overview about the problem & solution below for those interested, but if these details don't interest you, then you can safely skip the rest of this post.

For context, lemm.ee has been hosted on Hetzner servers for most of this year (having migrated from DigitalOcean initially), with everything except our database being hosted on the Hetzner Cloud side, and the database itself living on a powerful dedicated Hetzner server. This mix allows a great amount of flexibility for redeploying and horizontally scaling our application servers, while still allowing a really cost-effective way of hosting a quite resource-hungry database.

In order to facilitate networking between the cloud servers and the dedicated database server (which live in different networks), Hetzner provides a service named "vSwitch". This service basically allows you to connect different servers together in a private network. Unfortunately, I discovered quite quickly that this service is very unreliable. During the short few months that we have been using the vSwitch, we have gone through one extended period of downtime (where the service was just completely broken for several hours), as well as dozens (if not hundreds at this point) intermittent disconnects, where servers randomly lose their connections over the vSwitch. After such a disconnect, the connection never recovers without manual intervetion.

For most lemm.ee users, the majority of these vSwitch issues have been mostly invisible, as we have redundancy in our servers - if one server loses its connection to the database, other servers will take over the load. Additionally, I have generally been able to respond quite quickly to issues by redeploying the broken servers (or deploying other temporary workarounds). However, in addition to a huge amount of these issues which lemm.ee users hopefully haven't ever noticed, there have also been a few short periods of downtime this year so far, as well as a few cases of federation delays. These more extreme cases were generally caused by multiple servers losing their vSwitch connections at the same time.

After several attempts to work around these issues, I decided that we need to migrate away from vSwitch.

As of earlier today, lemm.ee is no longer using Hetzner's vSwitch at all!

I finally found enough time earlier today to focus on this migration, and I was able to successfully complete it. None of our networking is relying on the vSwitch anymore.

In the end, I went with quite a simple solution - I configured a host-level firewall (nftables) on our database dedicated server, which will deny all connections by default. Whenever any cloud servers are added/removed, their corresponding public IP addresses are added/removed in the allowlist of our database firewall. It would have been ideal to do this whole logic in Hetzner's own firewall, but that one unfortunately has a limit of only 10 rules per server, which is just not enough for our setup.

Bonus: our pict-rs server has been decommissioned!

Pict-rs is the software which Lemmy uses for everything related to media (image storage mostly). Initially, pict-rs required a local filesystem to store both files as well as metadata about files. Since the beginning, lemm.ee has used a dedicated server just for pict-rs, in order to ensure we could easily redeploy the rest of our servers without losing any images.

Over the past year, pict-rs has gained the ability to store files in object storage, and metadata in a PostgreSQL database. This meant that the server running pict-rs itself no longer contained any of the important data, so it became possible to redeploy without losing any images. Additionally, this meant that it would be possible to run multiple pict-rs servers in parallel.

While we had already migrated our pict-rs server to use object storage and PostgreSQL several months ago, we still had the single dedicated pict-rs server up until today. I have been planning for a while to decommission this server, and start running pict-rs directly on each one of our Lemmy application servers. Earlier today, I was able to complete this plan. This should hopefully mean that our pict-rs server is less likely to get overloaded, and it also means a tiny reduction in our overall monthly infrastructure bill (due to one less server running).

With the above changes, I think our infrastructure has become more robust, and hopefully, we will experience less issues with images, federation, and general downtime going forward.

That's all from me for now. Feel free to leave any thoughts or questions in the comments, and as always, I hope you're having a great day!

Hey folks!

This is a quick notice about a change to our moderation policy.

We have had a policy on lemm.ee for administration and federation nearly since the very beginning. This policy has also always included a section about moderator responsibilities. Today, we have made two changes to this policy:

1. The policy has been renamed to Policy for administration, moderation, federation - this is to make it clear that the policy is also relevant for mods
2. We have introduced a new responsibility for moderators, they must "Ensure that they only provide accurate and clear reasons for mod actions".

The reason for the addition is that mod log actions federate out to other instances, and are more or less permanent (due to how Lemmy and federation works right now). This means that users do not really currently have any easy way to clarify or defend themselves against inaccurate accusations in the mod log.

As always, I am very grateful to all mods for your efforts in building awesome communities on lemm.ee. I hope you can understand why this new policy is necessary - I do not want to make your lives more difficult, the goal is to just try and reduce any mod log related misunderstandings in the future.

Thank you for reading and have a nice day!

Hey folks!

We unfortunately had about half an hour of unplanned downtime today. This was caused by an issue with our hosting provider. The issue is solved for now, and I am planning to make some changes to prevent similar issues in the future. Sorry for the inconvenience!

Technical details

Our servers are communicating with our database over Hetzner's "vSwitch" service. Unfortunately, this service seems to be quite flaky - over the past few months, I have had to deal with the connection just dropping without recovering many times. Mostly this has not resulted in any noticeable downtime, as we have redundant servers, so even if one of them stops working, it won't affect lemm.ee users. However, in this instance, all of our API servers lost their connection to our database at the same time, which resulted in actual downtime.

I have now decided to migrate our setup away from the vSwitch in the near future to hopefully stop these issues for good. Should be possible to do this migration without any downtime, I just need to set aside some time to actually create an alternative solution for us, most likely over the coming weekend. I will update this post once the migration is complete.

Update: the migration is now complete! You can read more here.

Hey folks!

I've been steadily working through the roadmap for lemmy-ui-next (which is a new alternative Lemmy frontend), and it's getting to a point where I think https://next.lemm.ee is becoming quite usable. I've been personally using it as my main Lemmy frontend for several weeks now, and I know there are a few other brave users doing the same, so at this point, I'm confident enough to ask the wider lemm.ee population to try it out and share some honest feedback.

If you're at all interested in this project, I would massively appreciate it if you could spend some time using https://next.lemm.ee and letting me know how you feel about it. I'm interested to hear about things like:

• are you running into any issues or bugs
• are there any things that generally annoy you
• are you missing any features
• what would it take for lemmy-ui-next to become your preferred frontend
• anything else that comes to mind

Please keep in mind that this is still a work in progress - some features are planned but not implemented yet (see the roadmap linked above for more details), other features are half-finished and may be a bit buggy still!

Any feedback would really help me out, so please don't hesitate to share!

Hey folks

This is just a quick heads up that I need to perform some maintenance & upgrades on our database server, which unfortunately will require downtime. I don't expect the downtime to last for longer than 2-3 minutes, but just wanted to give a heads up first so you know not to be concerned.

That's all, hope you have a great week!

Edit: maintenance complete!

Hello, world!

Edit: first test edit!

Milestone 1 complete!

This is just a mini-announcement & celebration for the fact that I have completed the scope for the first milestone I set for myself in the roadmap.

Of course, I am still planning to keep improving and tweaking things as I go, but in terms of the raw list of features, the work for milestone 1 is complete. I am now going to take a day or two to clean up the code and work on some performance optimizations, and then in the later half of the week, I will continue working towards milestone 2, starting with commenting features!

If anybody is interested (and brave), please feel free to check it out at https://next.lemm.ee, and feel free to share any thoughts and feedback in the comments!

Intro

This project is an open source alternative frontend for Lemmy. It is built with Next.js.

• Preview environment: next.lemm.ee
• Source code & issue tracker: GitHub

Screenshots (desktop & mobile)

Goals

• Drop-in replacement for lemmy-ui
• Minimalistic design, following in the footsteps of other timeless link aggregator UIs
• Fast!
• Super basic NextJS architecture, taking advantage of features like the app router & server actions

Motivation

The original lemmy-ui has been extremely important for the growth of Lemmy, and the new lemmy-ui-leptos also looks quite interesting. One issue with both of these is that they are built using quite obscure technologies (Inferno and Leptos).

This project was created as an alternative for contributors who are already familiar with NextJs and want to use those skills on Lemmy. The beauty of open source is that anybody can build what they want, and all these alternative projects can happily coexist!

You can read more in the original announcement post here.

Hello, friends!

TL;DR: I am working on a new Lemmy frontend in nextJS. There is still much work to be done, but you can already have an early look at https://next.lemm.ee

First of all, quick note to lemm.ee users: I am making this announcement post in !meta@lemm.ee, as this is also a notice that I will be hosting an alternative frontend (lemmy-ui-next) for the first time on lemm.ee. Going forward, I will post updates about lemmy-ui-next in a separate dedicated community: !lemmy_ui_next@lemm.ee. If you're interested in future updates, please subscribe there!

What is lemmy-ui-next?

Lemmy is generally accessed through some kind of frontend UI. By default, Lemmy provides its own web interface (lemmy-ui), which you can find on the front page of most Lemmy instances (including lemm.ee). There are also several other independent frontends, for both the web and different mobile platforms, which I'm sure many of you are familiar with.

Lemmy-ui-next is a brand new alternative frontend, built from the ground up with modern and popular tooling - a framework known as NextJS. Lemmy-ui-next has (or aims to have) the following high-level features:

• Open source (AGPL)
• Drop-in replacement for lemmy-ui - same exact URL structure, so all existing links will continue working
• Very plain & minimalistic UI, strongly inspired by other link aggregator sites (of course including the original lemmy-ui!)
• Very basic and "typical" NextJS architecture, to encourage open source contributions
• Fully functional even when JavaScript is disabled (but works better with JS enabled!)
• Optimized data transfer between your browser and the server (filtering out only relevant data from the Lemmy API, caching, memoization)
• Strong focus on privacy and security (all authentication with the Lemmy API is done through secure httpOnly cookies, user IP addresses are not leaked to external image hosts, etc)

What is the current status of lemmy-ui-next?

I have mentally split the initial work I want to complete into 3 milestones:

1. Lurk - All read-only features of Lemmy
2. Participate - Voting/posting/commenting/DMs/reports, etc
3. Moderate - Handling reports, creating & managing communities, etc

I am now nearing completion of the first milestone. It's not 100% there yet, but you can already log in, browse, subscribe to communities and even vote. Some things may still look a bit wonky, and some features are still missing, but the core experience is getting there.

In terms of code contributions, I would ask anybody who is interested in getting involved to contact me first before working on anything. I am not looking for PRs just yet - the code structure is still a bit loose, and I am redefining it as I add more stuff. I would ideally really like to complete the first 3 milestones before opening things up for external contributors.

Who can use lemmy-ui-next?

At the moment, it is only hosted on this instance, at https://next.lemm.ee. I do not yet have any formal instructions for running it on other instances, but generally speaking, it is a simple NextJS app - to deploy it, you just need to do: npm install, npm run build and LEMMY_BACKEND=https://<your lemmy api here> npm run start.

Why not just improve lemmy-ui instead?

Lemmy-ui is an extremely important and valuable project. There has been a significant amount of hard effort put into it so far, and nobody can refute that it is the frontend which has really carried Lemmy to this point.

Unfortunately, there are some architectural problems with lemmy-ui (mostly related to how data is fetched and how sessions are stored in memory), all of which would require quite a significant rewrite to fix. Additionally, I think that the core technical solution used for lemmy-ui is just a bit too obscure, which has been an obstacle to my own contributions, as well as to contributions by others. If a rewrite is on the table anyway, then I believe a different technology is the best way forward.

Why not work on lemmy-ui-leptos instead?

Lemmy-ui-leptos is another rewrite of lemmy-ui, which is being lead by Lemmy maintainers. It is based around a Rust web framework called Leptos. I think this is really cool tech, and will be happy to host lemmy-ui-leptos on lemm.ee in the future as well.

There are a two key reasons why I personally decided to start working on another alternative, though:

• I have heard from several people on Lemmy that they feel like Leptos is a big barrier to entry in terms of them contributing
• Even for myself personally, I am very comfortable (and think I can move very fast) when working on something like NextJS, but with Leptos, I think the learning curve would be quite big and I would get much less done with any time I invest into it

My hope is that by providing a very vanilla alternative, I can provide an outlet for potential open source contributors who would like to work on Lemmy, but aren't prepared to do it with Leptos.

Does this mean that lemm.ee will change in ways I don't like?

First, let me be clear: lemm.ee will always host the default Lemmy frontend. This means lemmy-ui for now, and most likely lemmy-ui-leptos in the future.

I am however considering the possibility of switching things around at some point in the future, so that lemmy-ui-next will be hosted directly on lemm.ee, and lemmy-ui will be accessible on a different subdomain (like ui.lemm.ee). This would only happen once I have completed all 3 milestones for lemmy-ui-next. The main reason I am considering this is that I feel like I will always be in the best position to offer technical support to users on the frontend which I am myself maintaining. If you have any thoughts about this potential change, please let me know in the comments below!

That's about it for now!

This is something I've been thinking of doing for a while now, and I'm very excited to finally get the ball rolling! If you have a chance, please feel free to check out what https://next.lemm.ee looks like so far, and please let me know if you have any thoughts or feedback!
