Firefox, Bitwarden, and Tachiyomi are some that I use almost everyday

Favourite, not sure. Maybe my "favourite" would be the one which would be the hardest to replace with something I like.

There wouldn't be something i can think off that could be irreplaceable. However the hardest thing I like may be FanControl.

For the browser, Firefox is very nice, but it's "just" a browser if you think about it. There is brave, and other open source chromium alternatives if it disappears.

For mail clients, I also like the Mailspring design, however Thunderbird just got a new skin and damn it looks good too.

And for the rest, I don't really know. Either I don't remember right now, or no special "like" for the software. Or I like the closed source software convenience more (I may also have no idea of an open source alternative, or an equivalent in features open source).

It depends on the usage really.

Hard to answer but maybe Haiku or GNU Emacs

paperless-ngx

Linux, Tor, and the Ballistica game engine/BombSquad game (not fully open source as stuff used for sensitive data remains closed source 😔)

Edit: forgot git lol

OpenSCAD and Gitlab. I can quickly iterate on designs through code, push it to my Gitlab instance, and have my CI/CD pipelines pick it up, render it, and automatically slice it in some common profiles to send to Octoprint

I have used a lot of stuff over the years but my favorite would have to be a little command line program called cowsay. It takes whatever text you feed it and puts it in a speech bubble above a cow, hence the name.

Suricata

Definitely OpenFOAM. It competes with commercial software that costs thousands of dollars.

Firefox, Neovim, Pass (password store) and Wezterm. I heavily use all four of them.

I also need to give a special mention to Aegis Authenticator on Android.

Currently OBS and Motrix

I’ve been liking Digikam and Rawtherapee (which is an awful name for the record) for photo gubbins.

QGIS and OpenStreetMap for mapping

Neovim. It's an awesome editor and it has a great community and ecosystem.

For games:

• Anuto TD (found a few days ago, isn't super feature rich but still fun to kill time)

• Mindustry (never played a game like it before, ended up supporting by buying it on Steam)

• Supertuxkart (I love how many custom add-on karts and tracks I have)

For non-games:

• Termux (allows me to get apk files and install Revancify for add free yt)

• VLC (I don't mind slow updates and have yet to switch mostly because I can't find anything better that isn't more complicated than it needs to be and/or is closed source)

• KDE Connect (I have almost always had problems with moving files from and to my desktop via cord)

I'd include something like Linux, but I personally feel that's kinda cheating because of how large it is compared to the others.

Linux, of course. But another one that I use all the time, and love to death, is SageMath. It's the perfect blend of mathematics and programming for me.

vim

Linux, Firefox, Apache

Bulk Crap Uninstaller

Media Player Classic (I'm unsure if the latest iterations are or even if the Home Cinema edition is open source), TOR, qbittorrent, firefox, thinderbird, obs to name a few that I use regularly.

uhh probably uhh AOSP and calyx os

yay
