One step away.

BrowseParty isn’t just an extension, it’s a platform. With our Developer SDK, any website can become multiplayer by default: shared presence, synchronised actions, and even AI agent collaboration, all in real time.

Integrate co-browsing, chat, and follow/summon logic natively inside your own app.

Your users stay in flow, no tabs, no plugins, no friction. And when you’re ready, earn the Certified by MultiplayerWeb badge — a mark of trust, interoperability, and next-generation experience across the web.
