Babble is a lightweight, simple chat system deeply integrated with Discourse. It’s currently stable and updated to work with the latest version of Discourse. Feel free to give it a try!
It’s working great on mobile as well (and improving all the time! :D)
To install, use the standard method for installing plugins. Once installed, you may visit
https://<your-instance>/admin/chats to add chat channels (NB that a chat will not appear on your site until you’ve created a chat in this interface)
Babble currently offers two different possible permissions for chat channels:
- Groups (only members of the specified user group(s) may view and participate in the chat)
- Categories (only users with access to the given category may view and participate in the chat)
