I'm searching for open source webapp or SaaS project that will look like IRC in browser but with log history (and search). Those chats should be private. It can be very basic. I'm looking for something that will help programmers in a team to comnunicate.
Does something like this exist? I can't find anything like this. If there is no Open Source solution like this, maybe there is SaaS that provides this kind of Software, it can be free (as in beer) or not.
