Jan is an open-source desktop application that serves as a ChatGPT alternative, letting users download and run large language models fully offline on their own hardware via llama.cpp and MLX. It includes a model hub, OpenAI-compatible local API server, MCP server support, web search tools, and a companion terminal-based coding agent (Jan Agent).
Use cases
- run llms offline on my computer
- chatgpt alternative that works without internet
- chat with local models privately
- serve an openai-compatible api from local models
- download and manage local llm models
- run an ai coding agent in the terminal
- self-host ai chat with mcp server support
When to choose
- you want private, offline LLM usage with full data control
- you need a polished GUI for running local models on Mac, Windows, or Linux
- you want a drop-in local replacement for OpenAI's chat completions API
- you want MCP, web search, and agent features in one desktop app
When to avoid
- you only want a lightweight CLI or headless inference server without a GUI
- your hardware cannot run local models and you prefer pure cloud APIs
- you need a hosted multi-user chat service for teams
