Vitest is a Vite-native test runner with Jest-compatible API, native ESM and TypeScript support, and fast HMR-like watch mode. Replacing Jest in modern projects.
Reviewer scorecard
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
