Side-by-side comparison

Build-time optimizer that auto-memoizes React components and hooks, removing most manual useMemo/useCallback.

Fast dev server and build tool, now bundling with Rolldown; the default foundation for most non-Next.js frameworks.

Extremely fast Go-based bundler and minifier used under the hood by many tools.

Highly configurable bundler that powered a decade of apps; new projects mostly choose Vite or Rspack.
