we just released our new Multi-User Ajax Jabber Chat named Candy (acronym for Chats are not dead yet ).
Focused on real-time multi-user chatting
Easy to configure, easy to run, easy to use
Built for Jabber (XMPP), using famous technologies
Used and approved in a productive environment with up to 400 concurrent users
Works with all major web browsers including IE7
Take a look. We built it from scratch upon the famous Strophe.js Library and made it easily extendable and customizable (see the Project Page).
I hope we can gain some contributors and users of it .
We’re using in our Installation of it Openfire with Punjab as the HTTP-Bind Module. It works for over 400 Users concurrently in all major browsers seamlessly.
Of course you can also use another Jabber Server (we tested also on ejabberd).
If you have any ideas or bugs or whatever -> open an issue on github or send an email to our google groups mailinglist (All links on the project page).
