CopilotKit shipped an AG-UI integration that streams Claude Agent SDK agents into web and mobile frontends with generative UI and approval checkpoints. The adapter lets teams embed terminal-first Claude agents in React, Vue, Angular, and React Native without rewriting transport or state plumbing.
TanStack AI said its client and server are now two-way compatible with AG-UI, so TanStack clients can talk to any AG-UI server and vice versa. This matters because agent front ends and back ends can swap across framework boundaries without a migration rewrite.
