Good question.

The first and most important distinction is obviously which ecosystem you are more familiar / invested in (webpack vs. vite). It does make sense for projects deeply coupled to webpack to consider rspack first.

Putting that aside:

- Vite+ is a commercial offering with a company that can provide paid support. Rstack is a big corp by-product where their primary customers are internal teams.

- The Vite ecosystem provides way more options in choice of meta frameworks (Nuxt, Astro, React Router, Tanstack Start, SvelteKit, SolidStart...), and 3rd party tooling integrations

- While both written in Rust, our tools in general perform significantly better than rstack. With the upcoming full bundle mode, Vite 8 will be at least 2x faster than rsbuild across all categories (dev server start up, HMR, production build)

- Vitest and Oxlint are mature and widely used in production. rstest and rslint are both quite new and not even feature complete.
