Paste a URL and get a WCAG 2.2 audit in seconds, free and with no signup. Every failure comes with the offending HTML, the success criterion it breaks and the fix, so developers, QA and content teams can act on it straight away.
Checks aligned with global accessibility standards
Most accessibility claims start with barriers a scan can find in seconds: missing alt text, unlabeled form fields and buttons with no name. AccessBell surfaces them first, ranked by impact.
AccessBell is a thorough web accessibility evaluation tool, not a quick surface check. Every page loads in a real Chrome browser and is tested with the open-source axe-core rules after your JavaScript has run, so the results reflect what visitors actually get. Each failure is mapped to the exact WCAG 2.2 success criterion it breaks, with the failing HTML and a fix.
Where automation cannot decide, such as whether alt text is meaningful, AccessBell flags the item for manual review instead of guessing. That follows the W3C's guidance in Evaluating Web Accessibility: tools find many issues fast, and people confirm the rest. See exactly how we test.
WCAG is the technical foundation of accessibility law around the world. AccessBell checks against it once and reports in the language each regulation uses.
ADA Titles II and III, United States Section 508 U.S. federal ICT 
EN 301 549 European Union harmonized standard 
AODA Ontario, Canada EAA European Accessibility Act WCAG 2.2 organizes its success criteria under four principles: Perceivable, Operable, Understandable and Robust (POUR). A real WCAG check reports against each one, and is clear about what a person still needs to test. A generic accessibility score is not.

Every issue in an AccessBell report links to the exact success criterion it fails, its conformance level (A, AA or AAA) and a severity rank. Items only a person can judge are listed separately for manual review.
Accessibility is a team sport. AccessBell gives each person the detail they need, in the language they work in.
Failing markup, not vague warnings. Pages render in headless Chromium and run through axe-core, so what you see is the real DOM after your JavaScript runs.
Repeatable accessibility tests you can sign off. Pin each domain to a WCAG version and level, and every run is tested the same way.
Publish without breaking accessibility. Rescan a page after every update and catch the problems content edits introduce most.
Most US accessibility lawsuits and settlements cite WCAG 2.1 AA today. The UK public sector already monitors against WCAG 2.2, and it is the version the next rules are expected to adopt. AccessBell checks WCAG 2.2 AA by default and lets you switch to 2.1 or 2.0 for legacy reports.

|---|---|---|---|
| Published | December 2008 | June 2018 | October 2023 |
| Success criteria | 61 | 78 (17 new) | 86 (9 new, 4.1.1 Parsing removed) |
| Level A and AA criteria | 38 | 50 | 55 |
| What it added | The foundation: four principles (perceivable, operable, understandable, robust) and three conformance levels | Mobile, low vision and cognitive needs: reflow, orientation, text spacing, non-text contrast and status messages | Focus not obscured, dragging alternatives, 24px minimum targets, consistent help, redundant entry and accessible sign-in |
| United States | Section 508 standard for federal agencies and vendors | DOJ Title II rule for state and local government; the usual benchmark in ADA Title III cases | Not required yet; the safest target because it also covers 2.1 and 2.0 |
| European Union (EAA) | Not enough on its own | Required through EN 301 549 | Expected in the next EN 301 549 revision |
 United Kingdom public sector | Not enough on its own | Previous benchmark | Monitored against since October 2024 |
| Ontario, Canada (AODA) | Required for public websites | Exceeds the requirement | Exceeds the requirement |
| In AccessBell | Available | Available, plus ADA and EN 301 549 presets | Default (Level AA) |
Each version includes everything in the one before it, except 4.1.1 Parsing, which WCAG 2.2 retired. Content that meets WCAG 2.2 AA also meets 2.1 AA and 2.0 AA. Test a page with our free WCAG 2.2 AA checker or WCAG 2.1 AA checker, or work through the WCAG 2 AA checklist.
Key requirements and dates for the regions where most of our customers operate.
The Department of Justice final rule under ADA Title II sets WCAG 2.1 Level AA as the technical standard for state and local government websites and mobile apps.
For private businesses under Title III, courts and settlements consistently reference WCAG 2.1 AA, and increasingly WCAG 2.2 AA. Federal agencies and their vendors follow Section 508, which incorporates WCAG 2.0 AA.
Read the ADA compliance guideThe European Accessibility Act applies to many consumer-facing products and services, including e-commerce, banking, transport and e-books. Conformance is measured against the harmonized standard EN 301 549, which incorporates WCAG 2.1 AA for web content.
The Web Accessibility Directive already requires public sector websites and apps in member states to meet the same standard.
Work through the WCAG 2.2 checklistThe Equality Act 2010 requires service providers to make reasonable adjustments for disabled people, which includes digital services.
Public sector bodies must meet WCAG 2.2 AA under the Public Sector Bodies Accessibility Regulations 2018 and publish an accessibility statement.
See what changed in WCAG 2.2In Ontario, the Accessibility for Ontarians with Disabilities Act requires designated public sector organizations and businesses with 50 or more employees to meet WCAG 2.0 Level AA for public websites.
Federally regulated organizations are subject to the Accessible Canada Act, with standards developed by Accessibility Standards Canada.

Each issue includes the failing element, the WCAG criterion and a clear explanation of the fix.
Track your score over time and export reports that show auditors and leadership what has changed.
Start with a free scan of a single page. When you are ready, monitor every domain you manage from one dashboard, with continuous monitoring, alerts and team permissions.

A website accessibility checker is a tool that scans the code of a web page and flags barriers for people with disabilities, such as missing alt text, unlabeled form fields and missing page language. AccessBell maps every finding to the relevant WCAG success criterion and explains how to fix it.
Yes. You can scan any public page for free with no account. The Pro plan, $29 per domain per month, adds domain crawling, continuous monitoring, AI-assisted fixes, reports and team features.
Scans are based on WCAG 2.2 success criteria at Levels A and AA. Because WCAG is the technical benchmark behind the ADA, Section 508, EN 301 549, AODA and the European Accessibility Act, results are relevant to each of them.
No automated tool can guarantee compliance. Automated rules reliably catch objective, code-level failures, but some requirements, such as whether alt text is meaningful or focus order is logical, need human review. Read our guide to automated vs manual accessibility testing.
No. AccessBell does not inject a widget into your site. It finds issues in your source code and helps your team fix them properly, so the improvements are permanent.
Use the free scanner to check any public page on demand. With AccessBell Pro, scan staging before release, using custom HTTP headers to get past authentication, and production after each deploy. Each issue includes the failing HTML and the WCAG criterion, so it can go straight into a ticket, and the CSV export drops into your test tracker. Monitored pages are rescanned daily, and owners and admins are emailed when a new critical or serious issue appears.
Scan at least weekly and after every major release. Websites change constantly, and new content is the most common source of regressions. The Pro plan monitors your pages continuously and includes unlimited rescans.
