Accessibility work, from one page to a site.
A11y Scan brings automated checks, visual inspection, assisted review, and report export into a Chrome extension. Build the JSON that drives a scan on this website. A11y Scan is free to use; no account or subscription is required.
01 / Scan
Find issues across pages and widths
The Scan tab runs configured axe-core and heuristic checks in your browser, then keeps findings tied to the page and settings that produced them.
Workflow state scans
Name and capture page states after your own interactions. Review the resulting findings together and export a local workflow report.
Read the guide →Try an interaction fixture →Single-page scan
Choose WCAG 2.0, 2.1, or 2.2 and a conformance level. Review findings, incomplete checks, and affected elements on the current tab.
Read the guide →Try a scan fixture →Site crawl
Follow configured URL seeds with bounded page waits, optional local authentication, scoped API response mocks, and opt-in screenshot or HTML capture. Review page results, failures, and cross-page navigation findings together.
Read the guide →Try the crawl fixture →Multi-viewport scan
Scan a page at selected browser widths and compare which findings appear at each width. The browser window is restored afterward.
Read the guide →Try a responsive fixture →Scan Movie
After a scan, play a visual walkthrough of focusable elements. Pause or stop it as you inspect the page; it does not create findings.

02 / Review
Inspect what automation cannot settle
Use the page and assisted tabs to understand context, keyboard behavior, and reading order before deciding what needs a fix.
On-page highlights
Locate affected elements and show visual overlays for violations, tab order, and focus gaps directly on the page.
Read the guide →Try the overlay fixture →Keyboard tab
Inspect focusable elements, tab order, and keyboard-related cues. Human testing is still needed for the full interaction.
Read the guide →Try the tab-order fixture →Screen Reader tab
Inspect the page's reading-order model and listen with browser speech where available. This is an aid to review, not a device screen-reader test.
Read the guide →Try an ARIA fixture →Manual review
Work through checks that need human judgment alongside automated results instead of treating a scan as a conformance verdict.
Read the guide →Browse WCAG criteria →Color vision preview
Apply a local simulation filter to inspect how a page may appear with different color vision conditions, then reset the view.

03 / Explain and share
Carry findings into the next step
The scan profile and report keep the review reproducible. AI can help explain selected results when the browser supports its built-in model.
On-device AI conversation
Ask about the current scan or crawl findings with Chrome's built-in model when it is available. The AI explains results; it cannot add or certify findings.
Read the guide →Read beta availability →Local run comparison
Save runs in this Chrome profile, compare matching scopes and configurations, and review new, persistent and resolved findings.
Read the guide →Try a comparison fixture →Report export
Export a scan as JSON or a readable HTML report, including the effective scan configuration for context.
Read the guide →Read the quick start →Custom JSON scan profiles
Choose target, WCAG level, rules, widths, and supported modes in the free website builder. Download JSON and import it into the extension.
