What is AIMock and how does it work?

AIMock's a mock server for your full AI stack – LLMs, agents, vectors, tools. One config, one port. Fixtures for determinism.

How do I install and start AIMock?

npm install @copilotkit/aimock. npx aimock --config aimock.json --port 4010. Point your API base_urls there.

10+ out there: OpenAI, Claude, etc. Any OpenAI-compatible works. Full streaming, tools.

If you're building agentic apps, yes. Covers the gaps others miss.
