AG-UI includes a flexible middleware layer that ensures compatibility across diverse environments:
It also ships with a reference HTTP implementation and default connector to help teams get started fast.
AG-UI was developed based on real-world requirements and practical experience building in-app agent interactions.
AG-UI is complementary to the other 2 top agentic protocols
AG-UI was born from CopilotKit's initial partnership with LangGraph and CrewAI - and brings the incredibly popular agent-user-interactivity infrastructure to the wider agentic ecosystem.
