XMPP Chat Travis Bountysource bounties Translation status

Converse is a web based XMPP/Jabber chat client.

You can either use it as a webchat app, or you can integrate it into your own website.

It's 100% client-side JavaScript, HTML and CSS and the only backend required is a modern XMPP server.

Please support this project via Patreon or Liberapay


Converse is hosted and can be used at https://conversejs.org.

A demo showing anonymous login is available at https://conversejs.org/demo/anonymous.html and a demo which shows how you can embed a single chat room into a page is avialable at https://conversejs.org/demo/embedded.html.
