Lemonade
Lemonade is a self-hosted, open-source AI platform that runs entirely on local hardware, providing a complete AI runtime, graphical user interface, command-line interface, and REST API endpoints. It supports multiple modalities including text generation, image creation, speech synthesis, transcription, and text embeddings, making it a versatile foundation for diverse AI applications. The platform is free to use, with zero telemetry, ensuring full privacy and data sovereignty. Installable across Windows, macOS, and Linux desktops, as well as Docker environments, Lemonade simplifies local AI adoption by bundling inference engines like llama.cpp, ONNX Runtime, and stable-diffusion.cpp. Users can pull models from the built-in model registry, search Hugging Face directly, or import custom models. The platform is designed to scale from a single-user chat experience to a LAN‑wide AI server serving a household or small team. Lemonade offers an embeddable SDK for integrating AI capabilities into third-party applications, support for connecting to popular AI frontends via an OpenAI‑compatible API, and an MCP server mode. It is actively developed in the open with a welcoming community, following a philosophy of transparency and extensibility. The roadmap is shaped by open working groups, and the platform integrates with a wide range of open-source AI engines.
