I've never had joy using Jira, but if there's something nice out there I'm all for it. Mantis was a PHP one back in the day that just did issue tracking, and I loved it for that. But purely issue tracking, not the whole hog.

For a lightweight integrated solution I liked Trac quite a bit. JIRA+Confluence+Fisheye (to me at least) don't work as well together, although things are getting better over time.

I was hoping Gitlab filled this space. I keep hoping someone else will fill this space without doing any work. Time to dust off the open source hands! anyone that knows my code shudders in anticipation

If that was a known upvote for my poor code, the pain you are in right now is my revenge.

Considering the code bases of each product began by forking one of the others, it is amazing how hard they have worked since then to prevent them working together.

Other companies can only achieve this level of broken through acquisitions, distributed teams, competing for scarce internal resources and stack ranking. Atlassian achieved it by ignoring customer requirements, rapid feature growth, and monolithic java.
