Unified Collaboration Engine

U.C.Engine (Unified Collaboration Engine) includes:

  • several backend clients that provide additional features to your application (video streaming, file converters...)

U.C.Engine allows you to build real time applications like collaboration based services, live meetings, games or anything that fits well in an event driven philosophy.

U.C.Engine is a free software project written in erlang (server) and javascript (front client). It exposes a ReSTful HTTP API with JSON as its primary exchange format.
