What is it?

Converse is a web chat client for the XMPP (Jabber) protocol. It runs entirely in the browser with no server-side component of its own, connecting directly to an XMPP server. It can be used as a full-page app, as overlay chat boxes on top of a website, or as an embedded chat component placed into a specific element of a page.

The client covers one-to-one and group chat, along with message corrections, reactions, replies, retractions, and URL previews. It supports OMEMO end-to-end encryption, HTTP file upload, and a large set of XMPP extensions (XEPs). Known integrations include Prosody, ejabberd, and Openfire, as well as WordPress, Roundcube, and Elgg.

The app is extensible through a plugin architecture and is translated into more than 40 languages. It also offers a desktop build through Converse Desktop and Converse Tauri.
