Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“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.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Best UX for local models by far. The model browser with VRAM requirements shown upfront saves trial-and-error. Hardware optimization actually works.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“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.”
