Browser Extractor

About

Browser Extractor helps designers, developers, and product teams inspect any public webpage and extract usable design-system evidence directly from the browser.

It scans the active page and surfaces:

brand colors and color usage
typography, font families, weights, and size patterns
visual assets such as images, icons, and logos where detectable
technology hints such as frameworks, CMS, and analytics tools
structured design tokens based on observed UI patterns
UI/UX and accessibility audit findings
interactive element inspection with live visual preview controls
The extension is built for practical review and exploration. Users can inspect page structure, analyze styling decisions, preview alternative colors and typography on the live page, export token and audit data, and open a structured PDF audit report.

Browser Extractor is designed as a local-first workflow. Scan results, extracted data, and generated reports stay in the user’s browser unless the user explicitly exports them.

Best for:

design system discovery
competitive UI analysis
brand and style extraction
accessibility and UX review
frontend research and inspiration
product design audits
Important notes:

The extension works on the currently active tab after the user explicitly starts a scan.
Results are best-effort and should support, not replace, human review.
Cross-origin and protected resources may be skipped or flagged as warnings when browser security blocks access.
