Reviewer scorecard
“The UI is gorgeous — it feels like a native Mac app. Browse models, download, chat. No terminal needed. If Ollama is for developers, LM Studio is for everyone else.”
“The local server mode is the killer feature — run any local model with an OpenAI-compatible API. Drop it into any project that uses the OpenAI SDK.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Best UX for local models by far. The model browser with VRAM requirements shown upfront saves trial-and-error. Hardware optimization actually works.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
