Sirikata

Sirikata is an BSD licensed open source platform for games and virtual worlds. We aim to provide a set of libraries and protocols which can be used to deploy a virtual world, as well as fully featured sample implementations of services for hosting and deploying these worlds.

If you're looking to file a bug report, request a feature, or find out the current status of development, you're in the right place. For everything else, start at http://www.sirikata.com.
