Ollama vs LM Studio
Pick Ollama if you want an MIT CLI/daemon and an API on a machine you host (pairs with /stacks/open-webui-litellm). Pick LM Studio if you want a desktop GUI — and accept that the app is not open source.
Facts checked 18 Oct 2026. License, language, and GitHub activity come from the catalog or the project's own repo. "Not in the catalog row" means the public catalog dump does not store that number.

Self-hosting and resource needs
Ollama is MIT (ollama/ollama): pull a model, serve an API. LM Studio's GUI is proprietary (lmstudio.ai/app-terms); the project states the GUI is not open source while CLI/SDK/MLX engine pieces are MIT. LM Studio is free for personal and internal business use per their blog/terms. This is local inference, not ChatGPT Team seats. A ChatGPT-style UI stays on Open WebUI.
FAQ
- Is LM Studio open source?
- No. Their FAQ says the GUI app is not open source. CLI/SDK/MLX engine pieces are MIT. This page says so plainly.
- Do I still pay model vendors?
- Weights have their own licenses. Ollama/LM Studio run files you download. They are not a ChatGPT subscription.
- Where is the chat UI?
- /stacks/open-webui-litellm and /compare/open-webui-vs-librechat. Point Open WebUI at Ollama.
- How do I deploy Ollama?
- Install from ollama.com. Persist the model directory. Optional: put Open WebUI in front.
