Best Free Chrome Developer & Design Tools

Inspect fonts, extract colors, reverse-engineer Shopify stores, pull Etsy keywords, and access web archives instantly. All free, all local.

Developers and designers spend significant time inspecting websites — identifying fonts, extracting color palettes, researching competitor stores, and analyzing keywords. The browser's built-in DevTools can answer some of these questions, but the workflow is slow and manual. Each inspection requires navigating DOM trees, computed styles, and network requests.

These extensions eliminate that friction. Font Detector shows typography details on hover. Color Palette Extractor pulls every color from a page in one click. Shopify Theme Detector reveals which theme and apps a store uses. Etsy Keyword Extractor surfaces all tags from any listing. Wayback Quick Access gives instant access to archived versions of any page. Zillow Price/SqFt adds calculated price-per-square-foot data directly to listing cards.

Each tool does one thing well, runs entirely in the browser, and collects no data. They are built with Manifest V3 and designed to be lightweight enough to keep installed permanently without impacting browser performance.
