About

Bundlephobia is an open-source web app in the developer tools category (npm size). It opens in your browser, so there is nothing to install. You provide npm package name and get bundle size and composition. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (pastelsky/bundlephobia).
