What is Converse.js?

Converse.js connects to any XMPP server from a web page without a server component of its own. It can appear as overlay chat boxes, a full-page app or an embedded single chat room, so it suits both a team chat front end and a support widget on a site. Messages support styling, corrections, reactions and link previews, with OMEMO end-to-end encryption, status messages, desktop notifications and HTTP file upload. Desktop versions exist as Converse Desktop and Converse Tauri. Volunteers have translated it into 41 languages.

Good fit if

  • You run an XMPP server and want a web client for your users.
  • You want to embed a chat room in an existing website.

Look elsewhere if

Before you adopt it

Converse.js is MPL-2.0 and nothing in it is paid. One developer writes most of the code, so its pace depends on that person. You can host the static files yourself or try the hosted app at conversejs.org.
