Tigris.org is a mid-sized open source community focused on building better tools for collaborative software development.
You will not find thousands of unrelated projects here: every project fits into the Tigris mission.
You will not find dead projects here: every project is welcomed into the community with a commitment to see it through and active developers cycle among related projects.
Tigris.org is hosted by CollabNet, but the Tigris mission is one for the entire open source movement and one that has attracted senior open source developers from many organizations.
