Ask HN: What are good free project management tools?

Sandglaz: http://www.sandglaz.com I'm the Co-Founder and we use it ourselves internally as well. It's a freemium model (so there is a free version and a paid version). The paid version is 50% off until end of January.

Fogbugz, while not quite project management, has a 'startup' edition which is free. http://www.fogcreek.com/fogbugz/StudentAndStartup.html

Django Admin. A few models, couple of custom templates. An hours work and does everything we need, nice and simple.

Trello.com can be adapted for a variety of projects. It's free and is from a respected software firm, Fog Creek.

RedMine (Ruby on Rails) and Trac (Python) are nice, for technical projects.

Basecamp has a free tier.

andbang.com is new (i found it on HN) and dead simple. it's what i use most. podio is great if you need something more powerful and customizable.

I saw asana and I liked it
