Our verdict on Unused CSS Finder

Unused CSS Finder is a browser-based tool for web developers who want to identify removable CSS from web pages. It can scan a URL or accept pasted HTML, CSS, and optional JavaScript, then compare stylesheet selectors with a browser DOM. The product is best suited to solo developers and small teams focused on reducing page CSS rather than analyzing application code more broadly.

Its strongest feature is focused CSS analysis. The tool fetches same-domain CSS and JavaScript files, uses querySelectorAll to match selectors, and recognizes dynamic class patterns in Vanilla JS, jQuery, React, Vue, Alpine.js, Angular, and Svelte. It also handles media, supports, layer, and container rules, while preserving keyframes, font-face, imports, and vendor pseudo-elements. Reports include cleaned size, savings, and unused rule sets, giving developers concrete areas to review.

The Free plan includes URL scanning, pasted HTML, CSS, and JavaScript, and review of unused CSS rules. There are no paid tiers described, so the product keeps its scope simple but offers fewer workflow options than a broader static analysis platform. It runs on the web and does not include IDE support, CI/CD support, custom rules, or security analysis. Static analysis may miss runtime-generated or framework-generated styles, and the resulting CSS needs manual review before production use. Choose it for targeted CSS cleanup; choose another tool if you need repository integration, automated pipeline checks, or general code analysis.
