“The team ships fast and responds to feedback. Good sign.”
“This fills a real gap in the ecosystem. Worth adopting early.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
