October 2026 Summaries

PartyKit is shutting down its hosted platform in favor of PartyServer, a compatible Durable Objects-based framework that runs directly in users’ own Cloudflare accounts and underpins the Cloudflare Agents SDK. Beginning October 9, the platform will stop accepting new projects and preview environments, inactive projects will be removed on October 12, deployments and data-export access will end on October 16, and all remaining hosted projects and room data will be deleted when the service closes on October 23. Developers are encouraged to create new applications with PartyServer and deploy them through Wrangler, while existing projects can generally migrate with minor configuration and server-class changes, retaining partysocket clients after updating their host. Users must export room data stored in PartyKit’s Cloudflare account before October 16, although projects with significant usage or migration constraints may receive extended support if they contact the team. PartyServer, partysocket, y-partyserver, the PartyKit Discord, and Workers already deployed to personal Cloudflare accounts will remain available, though users must replace npx partykit deploy with wrangler deploy.
