VidaiMock is a tiny, lightning-fast simulator that lets you test your AI apps without the expensive API bills. It emulates OpenAI, Anthropic, Gemini, and more with zero configuration. Built in Rust for maximum speed! ✅ Physics-Accurate Simulation: Emulates real-world wire protocols (Streaming) and token delivery timing. (Chaos testing) ✅ Truly Dynamic ✅ Instant-On, Zero Fixtures: A single ~7MB binary ✅ Deeply Extensible: Use Tera (Jinja2) templates to mock any proprietary or internal LLM API
