Introducing AG-UI 1.0 🪁
The open protocol that connects ANY agent to ANY app, now with a stable spec.
AG-UI gives you an entire ecosystem for free.
Adopted and supported by Google, Microsoft, Amazon, Oracle, Anthropic, LangChain, Mastra, and more.
New in 1.0:
→ Subagents: expose delegated agent work
→ Metadata: send data from agent to UI
→ Multimodality (images, audio, video, docs)
→ Interrupts
→ Token usage per run
Every SDK is now generated from one schema, so TypeScript, Python and .NET all behave the same.
AG-UI 1.0 is fully backwards compatible.
