About Bundlephobia

Bundlephobia reports the minified and gzipped size of any npm package, its download time on slow connections and its dependency composition. It is free and has become the standard pre-install gut check for frontend teams.

Best for: Use this when you are about to add a dependency and want to know the bundle size price first.

Pros

  • Size, download time and dependency breakdown in one view
  • Compare versions to catch size regressions
  • Exports analysis shows per-import costs for some packages

Cons

  • Tree-shaken real-world cost can differ from the headline number
  • Occasionally fails to analyze unusual package setups
