AgentsKit Chat is a cross-framework application layer for interactive AI and agent experiences. Teams define routes, actions, components, sessions, and backend seams once, then render the same versioned behavior natively in React, React Native, Ink, Vue, Svelte, Solid, or Angular.

Deterministic routes can answer exact local facts before any backend call, reducing unnecessary latency and model use. When a model is needed, the application composes with AgentsKit's provider adapters instead of binding the UI to a single provider. It also keeps controller, tools, memory, RAG, and renderer responsibilities in their proper layers rather than duplicating them.

The project is MIT-licensed and distributed as @agentskit/chat and @agentskit/chat-cli.
