## What it is
Converse.js is a browser-based, fully client-side XMPP/Jabber chat client written in JavaScript. It can run as a standalone web app, a desktop app, or be embedded into existing websites as an overlay, widget, or full-page chat.

## Use cases
- add chat to my website without a SaaS service
- self-hosted web chat client for my XMPP server
- embed a chat room widget into an existing site
- encrypted group chat with OMEMO end-to-end encryption
- browser-based Jabber client with multi-user chatrooms
- integrate chat with my existing authentication system
- anonymous login webchat for a community

## When to choose
- you run an XMPP server and need a modern web or embeddable client
- you need data sovereignty and no vendor lock-in for user messaging
- you want a pluggable, customizable chat UI with 45+ language support
- you need OMEMO end-to-end encryption, file sharing, and message archiving in the browser

## When to avoid
- you need a native mobile or desktop-first messaging experience
- your backend is not XMPP (e.g. Matrix, Slack, or proprietary APIs)
- you want a hosted turnkey chat SaaS with managed infrastructure
- you need server-side rendering or non-browser environments
