Add Jan to your hut →

Jan is an offline-first desktop AI application that runs local models and exposes an OpenAI-compatible API on localhost. It handles model downloads and management through a clean interface and supports multiple model families simultaneously. The local server is the key developer feature — it lets you point Claude Code, VS Code extensions, or any OpenAI-API-compatible tool at Jan to use local models instead of cloud APIs, with zero cost and complete data privacy.

Free and open-source. Most often compared to Ollama and LM Studio — Jan's edge is the combination of a clean desktop UI and a production-ready local API server; it sits between LM Studio (GUI-focused) and Ollama (CLI-focused) in terms of developer experience.
