Knip Dead Code Detection

Knip is a comprehensive tool for finding unused code, dependencies, and exports in JavaScript and TypeScript projects. It helps maintain clean codebases and catch dead code before it accumulates.

Knip finds statically unreachable code. Reach for a different tool for unused CSS (PurgeCSS), runtime dead code paths, bundle-size trimming (bundler tree-shaking), or duplicate dependencies (npm-dedupe).
