Port of the project management tool ProjectPier to the Ruby on Rails framework
Version: 0.8 BetaRailsCollab is largely inspired by Basecamp, the communication-oriented project management solution from 37signals. RailsCollab even goes so far as to implement the BaseCamp API, allowing integration with many Basecamp integrated services and apps.
Operating System: Mac OS X
NOTE: Keep in mind though that while RailsCollab is inspired by Basecamp, it is by no means intended to be a clone of it. Whilst RailsCollab implements many security features, it is advised that you should be cautious when using it within an untrusted environment as it is still considered to be under development and thus may be susceptible to as-of-yet unknown security exploits.
