Framework for building agents and LLM applications with interoperable components and provider integrations.

## AI-native score: Unrated

Research coverage is 19/100. An AI-native grade requires 40/100. The provisional breakdown below shows the AI-native signals recorded so far. The AI-native score measures agent-readiness and is not a substitute for your own security or vendor-risk review. See [methodology](/methodology/) for how coverage and the grade are computed.
