I need to incorporate some real-time features in a web app, mostly notifications and ability to chat between users. I found that APE server fits my needs, they have impressive demos on their site etc. But soon after I started following their docs and tutorials it turned out that they're totally outdated and even the simple demo code on the main site doesn't work with the newest version :( Also it seems to be pretty much dead.
So, I'm looking for an active project with decent documentation. The only thing I really need is to be able to create a 'channel' where server could send (and receive) messages, preferably in json. Can you suggest anything?
Thanks for help! jan
