Compare the top tools for running AI models locally. Detailed comparison of LM Studio, Ollama, Jan, and Open WebUI with pros, cons, and recommendations for different users.
Hate typing commands? → Go with LM Studio
Don't mind the command line? → Try Ollama
Can't decide? → Start with LM Studio, then maybe try Ollama later
Both ship a desktop app now, so "GUI vs terminal" isn't really the deciding factor anymore. It's more about whether you want a tuning-friendly workbench (LM Studio) or a background service you can build on (Ollama).
Who it's for: People who want a nice interface without the tech hassle
What's good about it:
- Actually looks nice and is easy to use
- Download models by clicking buttons like a normal person
- Chat interface is built right in
- Shows you real-time stats about how your computer is handling things
- Fine-grained control over GPU offload, context size, and sampling without editing config files
- MLX engine on Apple Silicon, llama.cpp everywhere else
- MCP server support, so the model can use external tools
- Has an
lmsCLI and a headless server mode if you outgrow the GUI - Zero command line knowledge required
The downsides:
- Takes up more space on your computer
- Uses a bit more resources while running
- Not open source (free to use, including for work, but the app itself is proprietary)
Who it's for: Developers and anyone comfortable typing commands
What's good about it:
- Fast and doesn't hog resources
- Easy to integrate into your own projects - REST API plus an OpenAI-compatible endpoint
- Now includes a desktop chat app for Windows, macOS, and Linux
ollama launchwires it into coding tools like VS Code, Claude Code, Codex, and OpenCode- Modelfiles let you version and share custom model configurations
- Great if you want to automate things or run it headless on a server
- Open source (MIT)
The downsides:
- The CLI is still where most of the power lives
- Fewer knobs in the GUI than LM Studio exposes
- Bit of a learning curve if you're not technical
- The library now mixes in cloud-hosted models, which is easy to pick by accident when you wanted local-only
Who it's for: People who want an open source desktop app
What's good about it:
- Native app on Windows, Mac, and Linux - no Docker required
- Open source, and can talk to local models and cloud providers in one place
- Built-in model management
The downsides:
- Smaller ecosystem than LM Studio or Ollama
- Fewer advanced tuning options
Who it's for: People who want a ChatGPT-style web interface, often shared with a household or team
What's good about it:
- Polished browser UI that sits on top of Ollama or any OpenAI-compatible server
- Multi-user accounts, document chat (RAG), and conversation history
- Open source and actively developed
The downsides:
- Usually run via Docker, which adds setup complexity
- It's a front-end, not an inference engine - you still need Ollama or similar behind it
Who it's for: Honestly? Probably nobody starting out today
GPT4All was a great early option, but development has largely stalled - it hasn't kept up with newer model architectures. The app still works and Nomic still lists it, but you'll hit models it can't load. Use LM Studio or Jan instead.
- If you're new to this stuff - Start with LM Studio. It's just easier.
- Once you get comfortable - Give Ollama a try. It's actually pretty cool.
- If you want everything open source - Jan, or Ollama plus Open WebUI.
- Why not both? - Use LM Studio for casual chatting, Ollama for when you want to build something.
Most people I know end up using both tools depending on what they're doing!
