A11yInspect vs A11yScope

A11yInspect is a browser extension that works with the Inspect tool in DevTools to assess web-page accessibility against WCAG 2.2. Automated checks cover more than 600 issues across 30 Success Criteria, with a stated false-positive rate below 1%. Results classify findings as Fails, Validates, or Suggestions and map them to criteria and severity. Supported standards include WCAG, Section 508, EN 301 549, GIGW 3.0, and IS 17802. Manual review tools include bookmarklets for headings, tab order, grayscale, target size, text spacing, and forms, as well as a color contrast checker. The extension is available for Chrome, Edge, and Firefox and can examine a page or a specific element. Pages can be tested in any language, although the interface is English-only; the extension is for desktop browsers and cannot be used on mobile. The Free plan allows unlimited webpage testing without login or a credit card. Pro costs $120.00 per year and includes a 30-day trial without a card; users move to Free if they do not subscribe when it ends.

A11yScope scans public web pages for accessibility issues and gives practical next steps. It renders pages in a headless browser, including JavaScript, then runs axe-core checks for WCAG 2.1 AA. It also offers guidance on WCAG 2.2 criteria that may require manual review. Findings include fix guidance and copyable code snippets for common failures. Every plan, including Free, includes PDF and emailed reports. Free allows five page scans per hour without an account; a free account allows 50 scan attempts per 30 days and keeps the last three scans in history. Paid plans add weekly rescans and changes with links to page results. Starter costs $10 a month for one monitored site; Pro costs $49 a month for up to 10 sites; Agency costs $149 a month for up to 30 sites. A 7-day trial is available. A11yScope runs on the web and has no browser extension. Automated scans do not certify WCAG conformance, so keyboard and assistive-technology review is still needed.
