English | 简体中文

Rsdoctor is a build analyzer tailored for the Rspack ecosystem and fully compatible with the webpack ecosystem.

Rsdoctor is committed to being a one-stop, intelligent build analyzer that makes the build process transparent, predictable, and optimizable through visualization and smart analysis, helping development teams precisely identify bottlenecks, optimize performance, and improve engineering quality.

Rsdoctor supports all tools and frameworks based on Rspack or webpack, such as: Docusaurus, Rspeedy (Lynx), Storybook, Next.js, Nuxt, Re.Pack, Modern.js, Rsbuild, Rspress and Rslib.
