Niltalk is a web based disposable chat server. It allows users to create password protected disposable, ephemeral chatrooms and invite peers to chat rooms. Rooms can be disposed of at any time.



Niltalk supports in-memory / file / Redis as the backend for persisting room and session states.

This is a complete rewrite of the old version that had been dead and obsolete for several years (can be found in the old branch). These codebases are not compatible with each other and master has been overwritten.
