Description
Checking whether a webpage is accessible to people using screen readers or keyboard navigation used to mean either learning WCAG's dense rulebook by heart or paying a consultancy to audit every page. A11yInspect is a free browser extension that does a big chunk of that checking automatically, right in the browser tab you're already looking at, and highlights exactly which piece of code is causing which problem.
It runs 600+ automated checks across 30 WCAG success criteria (plus Section 508, EN 301 549, and India's GIGW 3.0/IS 17802 standards), with a claimed sub-1% false positive rate, and ships bookmarklets for quick checks like tab order, color contrast, and text spacing. The free tier covers unlimited page testing; the $120/year Pro tier adds a dashboard, screenshot capture, and downloadable audit reports, and Enterprise adds Jira/GitHub integration and custom standards. It's made by BarrierBreak, a 20+ year accessibility firm, and is also available as a VS Code extension and ESLint plugin for catching issues before code ships.
💬 Our review
The short version: for a developer or QA tester who wants to catch obvious accessibility problems before a page ships, A11yInspect's free tier is a genuinely useful daily-driver browser extension, backed by a company that does nothing but accessibility.
Against the two most common free alternatives — axe DevTools and Google Lighthouse's accessibility audit, both also free and widely used — A11yInspect's pitch is breadth (600+ checks across more standards, including region-specific ones like India's GIGW) and a lower false-positive rate, though none of the three replace a human accessibility review for judgment calls like whether alt text is actually meaningful. The VS Code extension and ESLint plugin are a real differentiator if you want issues flagged while writing code rather than after deploying, but pricing and feature details for those aren't published clearly, so budget time to test them yourself. For most developers, running it alongside axe DevTools costs nothing and only adds coverage; teams needing WCAG certification or Jira-integrated workflows should look at the paid tiers or a dedicated audit service.
