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
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
