An open-source benchmark suite comparing JavaScript minifiers such as esbuild, terser, swc, oxc-minify, uglify-js, and Google Closure Compiler on output size, gzip size, and speed. It runs each minifier in an isolated process with integrity verification and publishes continuously updated results.

Use cases

• compare javascript minifier output sizes
• which js minifier is fastest
• benchmark terser vs esbuild vs swc
• measure gzip size of minified javascript
• pick a minifier for my build pipeline
• track minifier performance over time

When to choose

• you need up-to-date, methodologically sound comparisons of JS minifiers
• you're choosing a minifier based on speed, size, or gzip compression
• you want reproducible benchmark methodology to extend to other minifiers

When to avoid

• you need a minifier itself rather than benchmark data
• you need benchmarks for non-JavaScript assets like CSS or HTML
• your code has unusual characteristics not covered by the benchmark fixtures
