Sara

Sara is an MIT-licensed AI companion and coding assistant that runs on your own server. It combines a customizable personality and editable persistent memory with planning, document reading and coding project workspaces.

For development work, Sara can edit files, use Git and run commands and tests, with approval controls for risky actions. It supports local models through Ollama, vLLM and llama.cpp, as well as supported cloud providers. A web interface and desktop and mobile clients connect to your server.

The core is written in TypeScript and runs on Node.js 24 or newer with no runtime dependencies. Install using the documented native or Docker Compose setup. Users provide their own hardware and models; cloud model services may charge separately. Capabilities and results depend on the selected model and deployment environment.
