Stylus is a browser extension for Chrome, Firefox, and Chromium-based browsers that lets users restyle websites by installing and managing CSS themes (userstyles). It is a privacy-focused fork of Stylish with no analytics, a built-in CSS/LESS/Stylus editor, and support for UserCSS styles from external galleries.

Use cases

  • install dark themes for websites
  • customize the appearance of web pages with css
  • manage userstyles across chrome and firefox
  • write my own css overrides for a site
  • replace stylish without tracking
  • sync browser styles via webdav or google drive
  • find skins for popular websites

When to choose

  • you want to restyle websites with community themes and no telemetry
  • you need a built-in editor with linting and live reload for authoring userstyles
  • you want style auto-updates, cloud sync, and JSON backup

When to avoid

  • you need to modify page behavior or scripts rather than appearance
  • you want a native desktop theming tool rather than a browser extension
