A2UI is an open standard and set of libraries that lets AI agents generate rich, interactive user interfaces by sending declarative JSON component descriptions that clients render with their own native widgets (Angular, Flutter, Lit, etc.). It is designed to be secure (data, not executable code), LLM-friendly, and framework-agnostic, with renderers and transports like A2A included.

Use cases

• let ai agents render interactive uis safely across trust boundaries
• generate dynamic forms and cards from an llm agent
• stream incrementally updatable ui from a chatbot
• render the same agent ui payload on web, mobile, and desktop
• build a custom component catalog for agent-generated interfaces
• debug and preview agent ui json payloads

When to choose

• you need agents to present rich interactive UIs instead of plain text
• security matters and you cannot execute LLM-generated UI code
• you want one agent UI format rendered across multiple client frameworks
• you are building chat or agent clients with Angular, Flutter, or Lit

When to avoid

• you need a fully stable, frozen specification (v1.0 is still a release candidate)
• your UIs are static and don't need agent-driven generation
• you need pixel-perfect control over rendering rather than a trusted component catalog
• your stack has no supported renderer yet
