Accessibility Tracker Scanner

About

Accessibility Tracker Scanner finds WCAG accessibility issues on any web page — instantly, privately, and for free. It runs the industry-standard axe-core engine entirely inside your browser, so nothing is ever uploaded and no account is required.

Whether you're a developer, QA engineer, designer, or accessibility specialist, you can scan a single page in one click or crawl a whole site, see every issue highlighted right on the page, and export a shareable report in seconds.

WHAT YOU CAN DO
• Scan any page for WCAG 2.1 A, AA, and AAA issues using axe-core
• Scan pages behind a login — it runs in your real browser session
• Check multiple pages in one run: record your navigation, paste a URL list, load a sitemap, or auto-crawl
• See issues highlighted directly on the page, with click-through details and the exact failing element
• Export a clean HTML report, or JSON / CSV for your bug tracker or spreadsheet
• Re-open and re-export past scans from your local history
• Group issues by rule or by page, and filter by severity (critical / serious / moderate / minor)

TWO WAYS TO SCAN
• Quick scan — click the toolbar icon and press "Scan This Page" (or Ctrl+Shift+A / Cmd+Shift+A) to check the current page.
• Full scanner — open the side panel (Ctrl+Shift+S / Cmd+Shift+S) to discover and scan multiple pages, review grouped results, highlight issues on the page, and export reports.

PRIVATE BY DESIGN
• 100% local. The axe-core engine is bundled in the extension and runs on your device.
• No account, no sign-in, no tracking, no analytics.
• Nothing you scan is ever uploaded — the only network requests are to the pages you choose to scan, exactly like your browser loading them.
• Your scan history and settings live only in your browser's local storage. Clear them anytime from the options page.

POWERED BY AXE-CORE
Accessibility checks are performed by axe-core, the widely used open-source accessibility testing engine, covering WCAG 2.0, 2.1, and 2.2 success criteria across levels A, AA, and AAA.
