OpenAI-compatible MITM proxy to record and replay API sessions

Mannequin is an OpenAI-compatible MITM proxy for testing AI-enabled applications. It sits between your application and a real backend model API, records every request/response exchange to disk, and later replays those exchanges without calling the real backend, so your tests and demos run fast, offline, and for free.

mannequin record proxies live traffic to a backend such as https://api.openai.com/v1 while saving every exchange; point your application at http://127.0.0.1:8080 instead of the real API. Then mannequin replay serves the recorded responses back with no API key and no network calls, so test suites, CI pipelines, and demos run deterministically at zero cost.
