The honest brief
Jan
Bundles its own model runner so it works offline out of the box — no account, no telemetry, and no paid tier.

- Open source (Apache-2.0), no paid tier
- Bundled model runner + model hub
- BYO cloud keys when wanted
- Local OpenAI-compatible server
- More setup friction than LM Studio
- Limited tool-calling vs full agent stacks
- Local model speed bound by your hardware
- Smaller ecosystem than Ollama

- Local models or BYO API key
- Built-in MCP servers, agents, memory
- Docker support for Linux, Mac, Windows
