| Fact | Rolldown | Terser |
|---|---|---|
| Purpose | Rolldown is a Rust-based bundler for JavaScript with a Rollup-compatible API and esbuild feature parity. | Terser is an industry-standard JavaScript minifier that shrinks variable names, removes whitespace and comments, and drops unused code. |
Rolldown suits JavaScript developers looking for a bundler with TypeScript and JSX transforms and a Rollup-compatible plugin API. Its guidance points most application developers toward using it through Vite and library authors toward tsdown.
Terser suits developers who need to minify JavaScript through a command line, Node.js API or browser loading. Its configuration options also suit workflows that need source maps or a specific ECMAScript target.
