While I don’t like the main Jira software, the Jira Service Management part is actually kind of decent for my needs. It basically allows me to create a help desk for my small business, where they can report issues and I can view them in the Jira app. It’s somewhat limited on the free tier, only allowing 3 agents, but it works plenty fine for my use case.
As for the actual Jira software, I wouldn’t use it, since my workflow needs don’t require it.
