PartyKit provides serverless real-time infrastructure with stateful servers at the edge. Built on Cloudflare Durable Objects. Now part of Cloudflare.
Reviewer scorecard
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“Stateful edge servers are the right abstraction for real-time. The Cloudflare acquisition ensures long-term viability.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“Durable Objects made simple. For real-time features without WebSocket infrastructure complexity, PartyKit is excellent.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
“Edge-first real-time infrastructure is the future of multiplayer applications. PartyKit is building that.”
