Autoprefixer is a PostCSS plugin that parses CSS and automatically adds vendor prefixes to CSS rules using browser support data from Can I Use. It is widely adopted, recommended by Google, and used in production by companies like Twitter and Alibaba.

Use cases

• add vendor prefixes to css automatically
• stop writing -webkit- and -moz- prefixes by hand
• process css in webpack or gulp builds with browser prefixes
• support older browsers with css grid prefixes
• remove outdated css prefixes from stylesheets
• integrate css prefixing into a postcss pipeline

When to choose

• you write modern CSS and want prefixes applied automatically based on browser support data
• you already use PostCSS or a bundler like Webpack or Gulp in your build pipeline
• you need configurable browser targets, e.g. via Browserslist, to control which prefixes are added

When to avoid

• your build targets only evergreen browsers that no longer require vendor prefixes
• you need CSS polyfills or transpilation of modern syntax to older syntax rather than prefixing
• you are not using a CSS processing pipeline and prefer a pure preprocessor like Sass without PostCSS
