Bundlephobia is a web service and API that reports the bundle size and performance cost of npm packages, including historical trends and package composition. It helps developers evaluate the weight of a dependency before adding it to a frontend project.

Use cases

  • check the bundle size of an npm package before installing it
  • compare the cost of alternative frontend dependencies
  • scan a package.json to see total bundle impact
  • view historical size trends of a package across versions
  • get package size badges for a README
  • find lightweight alternatives to heavy npm packages

When to choose

  • you want to know the minified/gzip size of an npm package quickly
  • you are auditing dependencies for performance budgets
  • you need an API or badges for package size data

When to avoid

  • you need full bundle analysis of your own application build (use webpack-bundle-analyzer)
  • you need server-side or non-JavaScript package metrics
