bundle-stats

bundle-stats is an in-depth bundle analyzer for webpack, Rspack, Vite, Rollup, and Rolldown that provides detailed reports on bundle size, assets, modules, and packages. It supports comparing multiple builds side-by-side to identify changes, duplicate packages, and new dependencies. Current stable version is 4.22.1, released in April 2025, with active maintenance and frequent updates. Key differentiators include its cross-bundler support via rollup-plugin-webpack-stats, insights like cache invalidation and initial JS/CSS metrics, and a CLI for CI integration. Ships TypeScript types. Requires Node >= 14.
