Ollama
Pros

- The easiest local setup available; genuinely one command
- Huge model library, updated within days of new open releases
Cons
- Quality depends on your hardware — small models on a laptop are far below frontier cloud models
- Command-line first; the built-in chat UI is minimal
- Large models need 16–64 GB of RAM or a serious GPU
LM Studio
Pros
- No terminal needed — the friendliest way to try local models
- Tells you which models will actually fit your machine before you download
- Local document chat keeps sensitive files off the cloud
Cons
- Closed source, unlike Ollama
- Commercial use requires contacting the company
- Same hardware limits as any local runner — small models on small machines
