Reviewer scorecard
“Stateful edge servers are the right abstraction for real-time. The Cloudflare acquisition ensures long-term viability.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Durable Objects made simple. For real-time features without WebSocket infrastructure complexity, PartyKit is excellent.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Edge-first real-time infrastructure is the future of multiplayer applications. PartyKit is building that.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
