Rolldown is primarily designed to serve as the underlying bundler in Vite, with the goal to replace esbuild and Rollup with one unified build tool. Although designed for Vite, Rolldown is also fully capable of being used as a standalone, general-purpose bundler. It can serve as a drop-in replacement for Rollup in most cases, and can also be used as an esbuild alternative when better chunking control is needed.
