Converse.js

Converse.js is a client‑side XMPP chat application that runs entirely in a web browser. It can be deployed as a standalone full‑page app, an overlay widget, or an embedded component inside an existing site, and it can also be packaged as desktop or Tauri builds. The software supports a wide range of XMPP extensions, including end‑to‑end encryption with OMEMO, multi‑user chatrooms, file sharing via HTTP upload, message styling, reactions, and URL previews. Users can log in with existing XMPP accounts, register anonymously where the server permits, or create new accounts through in‑band registration.

The project targets developers, community managers, and organizations that need a customizable, self‑hosted messaging solution without subscription fees. Its plugin architecture and extensive configuration options allow developers to extend functionality or adapt the UI to specific requirements. Internationalization covers more than 45 languages, and the client works on both desktop and mobile browsers.

Converse.js is released under the MPL‑2.0 license, is actively maintained, and integrates with many XMPP servers and third‑party platforms. Documentation includes quick‑start guides, configuration references, and plugin development resources, supported by an active contributor community.
