Overview

Rolldown is a high-performance JavaScript bundler built in Rust with strong Rollup compatibility.

Pros

  • Built in Rust for fast bundling
  • Designed for Rollup compatibility
  • Strong tree-shaking support
  • Good fit for modern ESM projects
  • Backed by the Vite ecosystem

Cons

  • Still maturing
  • Smaller plugin ecosystem than Rollup
  • Some compatibility gaps remain
  • Documentation may lag behind adoption

Verdict

Rolldown does well by combining Rust-powered speed with a Rollup-like workflow. It is best for teams building modern JavaScript or Vite-based projects that want faster bundling. The main trade-off is its relative immaturity compared with established bundlers.
