A command-line tool that automatically refactors CSS by examining a site's live DOM in a headless browser and reverse-engineering a clean new stylesheet. It generates a fresh CSS definition that reproduces the original rendered styles down to the pixel, ignoring the source CSS files entirely.

Use cases

• refactor legacy CSS that has accumulated contradictory rules
• generate a clean stylesheet from a rendered page
• reverse engineer CSS from a live DOM
• clean up stylesheets without reading the original CSS files
• convert a style guide page into a fresh CSS baseline
• remove redundant cascaded styles from a site

When to choose

• you have old, messy CSS whose rules contradict each other and want a clean regenerated stylesheet
• you have a complete example DOM or living style guide covering your site's states
• you want to derive styles from rendered output rather than source files

When to avoid

• you need to process a whole multi-page site (not yet supported)
• you need a maintained tool - it depends on the deprecated PhantomJS and hasn't been updated since 2015
• your pages have many dynamic states not present in the markup you provide
