TogetherJS is a free, open-source JavaScript library by Mozilla that adds real-time collaboration features to any website via a copy-paste script. Users on the same page can see each other's cursors, edits, and browse together, with a relay hub server (now available as a Cloudflare Workers port) syncing messages.
Use cases
- add real-time collaboration to my website
- let two users co-browse the same page together
- show shared cursors and live edits between users
- build a collaborative drawing or text editing app
- add co-watching or shared browsing to a web app
- self-host a websocket relay for collaborative sessions
When to choose
- you want drop-in real-time collaboration on an existing website with minimal setup
- you need shared cursors, audio chat, and co-browsing without building from scratch
- you want a customizable, self-hostable collaboration layer
When to avoid
- you need support for Internet Explorer or legacy browsers
- you want a fully maintained product with active development and support
- you need collaboration for native mobile or desktop apps rather than the web
