Connects to LangChain, CrewAI, Mastra, the OpenAI and Claude Agent SDKs and other backends through the AG-UI protocol. CopilotKit Intelligence adds hosted or self-hosted AG-UI streams, user memory, Slack/Teams channels and product analytics: free hosted use covers 1,000 interactions per organization a month; Pay as you go is $49/mo per organization with 10,000 interactions included, then metered; Annual is custom and can run offline.

Why this score: The clearest path to an in-app React/Next copilot: free MIT SDKs, generative UI, AG-UI hooks into most agent backends, and a free forever Developer cloud. Scores below the Vercel AI SDK because it is a UI/agent-front layer rather than the default TS toolkit, and Team cloud is $100/seat. Stronger than newer UI-only kits on maturity (Series A coverage, Fortune 500 logos, ~38k stars).
