Reviewer scorecard
“10x faster package installs, native TypeScript, and built-in test runner. It's replacing Node.js in my new projects.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Speed is real and measurable. Node.js compatibility is good enough for most projects. The future of JS runtimes.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“Bun is forcing Node.js to improve. Competition in runtimes benefits everyone. Speed + DX is the winning combination.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
