Years in this space
I've evaluated a lot of these over the years. What stands out here is works offline after initial setup — handled better than most — and free and open source. Requires capable hardware for larger models is my one real gripe. Worth the time if this is your use case.
Solid for our team
We rolled this out across the team last quarter and cross-platform (macOS, Linux, Windows). Works offline after initial setup fits neatly into how we already work, and works offline after initial setup removed a step we used to do by hand. No built-in graphical interface by default, which is the main caveat, but it has held up under daily use.

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on custom Modelfile for tailored model configs, and free and open source caught me off guard. No built-in graphical interface by default is why this isn't a perfect score, still, I'd recommend giving it a real trial.
