# a2ui-project/a2ui

> A2UI is an open standard and set of libraries that lets AI agents describe user interfaces as declarative JSON, which client apps render with their own native components (Flutter, Angular, Lit, React). It solves the problem of safely showing rich, interactive agent-generated UIs across trust boundaries.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
