PartyKit offers an open-source deployment platform and developer libraries to add real-time multiplayer collaboration (e.g., whiteboards, games, code editors) into applications with minimal infrastructure work. The platform runs on Cloudflare technology and supports both cloud and on-premise hosting to meet enterprise regulatory needs. PartyKit can integrate LLMs (such as OpenAI or in-house models) to enable human–AI collaborative agents, handling long-running processes, memory, and context. The product moved from an initial version built with Tldraw to a full rewrite to support broader use cases, and has been in open beta since July. The company recently announced its first hires and is launching the platform into general availability while preparing premium enterprise features including teams, analytics, and compliance. Founder and CEO Sunil Pai, who previously worked at Cloudflare and on multiplayer apps at Meta’s Oculus, leads the effort to commoditize multiplayer infrastructure for developers.
