Lemonade is a local AI inference server and desktop application that provides OpenAI/Anthropic/Ollama-compatible APIs with support for multiple backends (llama.cpp, vLLM, whisper.cpp, Kokoro, etc.). The C++ server core handles model lifecycle, routing policies, multi-modal inference, and telemetry, while the React/TypeScript frontend (Tauri desktop app and web build) offers a full GUI for chat, image/audio generation, transcription, and model management. The repository also includes a CLI client, tray application, extensive integration tests, and automated documentation generation. Architecture follows a clean backend-descriptor registry pattern with generated boilerplate, platform abstraction for process/archive/path operations, and a sophisticated routing policy engine for model selection.
