uCSS is a Node.js tool that crawls websites or local HTML files to find unused and duplicate CSS selectors, with match counts per rule. It works both as a command line tool and as a library, and supports config-driven crawling with login, whitelists, and exclusions.

Use cases

• find unused CSS selectors on my website
• detect duplicate CSS rules in a stylesheet
• crawl a site to see which CSS rules are never used
• audit CSS usage across pages behind a login
• find dead links while crawling a site
• count how often each CSS rule matches

When to choose

• you want to identify unused or duplicate CSS selectors across a site or HTML codebase
• you need a CLI or Node library for CSS usage analysis
• you need to crawl authenticated pages with a config file

When to avoid

• you want to automatically remove unused CSS from a stylesheet (use UnCSS instead)
• you need detection of JavaScript-toggled rules, inline styles, or internal style sheets
• you need a actively maintained tool with recent updates
