Stop paying OpenAI and Anthropic to run unit tests in CI/CD. Agent Mock Twin ingests standard HAR 1.2 recordings or OpenAPI 3.0 blueprints and hosts a local, zero-latency network twin. 100% deterministic outputs. Zero outbound billing.
| Method | Path | Provider | Tokens | Description |
|---|
Agent Mock Twin records or ingests real LLM provider traffic (OpenAI, Anthropic, Gemini) via standard HAR 1.2 or OpenAPI 3.0 files. It then hosts a zero-dependency local mock server that answers agent requests deterministically in microsecond latency with zero outbound token egress.
No. The backend runtime is built 100% on the Python 3.10+ standard library (http.server, sqlite3, dataclasses, urllib.parse). It runs anywhere Python is installed without pip install.
Developers run their test commands wrapped via agent-mock run -- pytest tests/. The CLI automatically spins up the mock server in a background thread and redirects OPENAI_BASE_URL and ANTHROPIC_BASE_URL to the local twin.
One-time investment of $19 for permanent lifetime access. Deploy autonomous agent testing without monthly subscriptions.
