esbuild-visualizer

Visualize and analyze your esbuild bundle to determine module sizes and composition. Current stable version is 0.7.0, with irregular release cadence. Generates interactive HTML charts (treemap, sunburst, network) from esbuild metafiles. Key differentiator: works specifically with esbuild's metadata output, producing visual bundle analysis without including source code content. Requires Node >=18, ships TypeScript types. Alternative to webpack-bundle-analyzer for esbuild users.
