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
