You are so right about Atlassian tools. I cannot stand Jira. Very often, it's easier and faster to fix a bug, then to update the status in Jira. It's clutterware.
Speed isn't the best, but it was either that, use Redmine with a massive config or wrap the shop up.
Then they moved everything to a cloud hosted solution, but the assumption of requests being effectively zero latency was still built-in, so now firing hundreds of requests with high latency makes everything feel super sluggish.
I'm working on my own issue tracker [0] that stores everything locally, which means no network latency. Eventually I'd like to build a sync backend for it so you can share it with a team, but for now everything runs locally.
My company had paid for the locally hosted version of JIRA for security policy reasons.
The cloud is the original code base and the on premise is a FORK! Can you believe it? It's not even the same code and the on premise solution is so far behind.
My rage builds even just trying to use the search bar on JIRA. Keys don't get captured and get registered as page hot keys, or some keys are registered and others aren't. Crazy, just give me a dumb static search bar if you're not going to make life better. /Rant
