I posted a bit of research I did for some externally hosted tools previously. Here is a quick rundown of some self-hosted tools.
- VersionOne Community (free - I've used it and I like it, 5 user limit)
- XPlanner (free OSS, seems good, hasn't been updated since 2006)
- RedMine (free OSS, not really agile, more of an issue tracker like Jira)
- ScrumWorks Basic (free, pro version has more features)
- AgileTrack (new to me, seems to cover the bases - didn't see any burn down charts)
- VersionOne Team (like V1 Community except you get support)
- Project Cards (new to me, seems to cover the bases - didn't see any burn down charts. The UI looks a little MS Access)
- OnTime Express (not agile out of the box, but can be customized to support, similar to JIRA+Confluence in that underneath it is an issue tracker and a wiki)
- ExtremePlanner (nice simple system)
- Trichord (more lean than agile, kanban + burndown - interesting)
- OnTime Pro (more features than OnTime Express)
- TargetProcess On-site (new to me, seems similar to V1 and Rally)
- Jira Enterprise (an issue tracking system, but combined with GreenHopper can be very agile)
- VersionOne Enterprise (unlimited users)
- ScrumWorks Pro (more features than Basic)
There are several free options here 2 commercial and 2 OSS. If I only needed 5 users I'd pick V1 otherwise I'd go with XPlanner. There seems to be a sweet spot around $2000. In this range I'd pick either Trichord or ExtremePlanner.
