Ask HN: Free Web Based Project Management

I've heard many positive reviews of Pivotal Tracker: http://www.pivotaltracker.com/

If you're hosting it on your own I've also heard that Redmine is great: http://www.redmine.org/

I just started using Pivotal Tracker for a small project this week after reading about it here on HN. So far, so good.

What specifically are you looking for?

Github has a free plan for open source projects: https://github.com/plans

bitbucket is also fairly popular these days: https://bitbucket.org/plans

Project Pier is pretty good, it's the open source branch of ActiveCollab http://www.projectpier.org/

If you don't mind hosting it yourself there is open atrium.

I run a little app called Reverb (http://reverbapp.com) if you're interested.

Is it free because it's in beta?

There will always be a free version. There will at some point be a paid version with more upload space etc. (more info here: http://reverbapp.com/help/#how-much-does-it-cost).
