For a long time, web tools were written in JavaScript. Webpack, Babel, ESLint—all JavaScript. But a massive shift occurred: the next generation of tools is being written in Rust.
The Speed Bottleneck Problem
JavaScript is single-threaded and JIT-compiled. It struggles with CPU-intensive tasks like bundling millions of lines of code. When your project grows to thousands of files, the difference becomes unbearable.
The irony: JavaScript tooling became the slowest part of JavaScript development.
Rust changes this equation. It operates at near-native speeds, uses memory safely without garbage collection, and can parallelize across all CPU cores.
Key Rust-Powered Tools
The Rust Tooling Revolution
| Tool | Replaces | Speed Improvement |
|---|---|---|
| SWC | Babel | 20x-70x faster |
| Turbopack | Webpack | 10x faster (cold), 700x (incremental) |
| Rolldown | Rollup | 10x-30x faster |
| Oxc | ESLint/Prettier | 50x-100x faster |
| Biome | ESLint + Prettier | 35x faster |
What This Means for You
Good News
You don't need to learn Rust. You just benefit from instant dev server starts and faster CI/CD pipelines.
- Dev servers start instantly: No more waiting 30 seconds for Webpack
- HMR is actually fast: Changes reflect in milliseconds
- CI/CD costs drop: Faster builds = cheaper cloud minutes
- Developer happiness: Less time waiting, more time coding
Key Takeaways
- Rust tooling is 10x-100x faster than JavaScript equivalents
- SWC, Turbopack, and Rolldown are production-ready
- You don't need to learn Rust to benefit
- Expect Rust tools to become the default within 2 years
