7 Best Accessibility Checker Chrome Extensions in 2026
7 Best Accessibility Checker Chrome Extensions in 2026
Checking your website for accessibility issues should not require an expensive consultant or a week-long audit. Chrome extensions can scan a page in seconds and flag WCAG violations you can fix immediately.
We installed and tested the most popular accessibility checker extensions in the Chrome Web Store. Here is how they compare.
1. Accessibility Checker -- ADA & WCAG Scanner
Best for: Quick spot checks with plain-English results
Our own extension runs a full WCAG 2.2 Level AA audit using the axe-core engine. What sets it apart is the output: every issue is described in plain English with a compliance score (0-100) and color-coded severity breakdown. Click any issue to highlight the element on the page.
It also detects FTC-flagged dark patterns and alerts you to ADA Title II deadlines on government domains.
- Price: Free
- Engine: axe-core
- Permissions: activeTab, scripting, storage (minimal)
- Privacy: All scanning is local -- no data sent to servers
- Install from Chrome Web Store
2. WAVE Evaluation Tool
Best for: Visual overlay of accessibility issues directly on the page
WAVE (Web Accessibility Evaluation Tool) by WebAIM has been around for years and remains one of the most widely used options with over 700,000 users. It injects icons directly into the page to mark errors, alerts, and structural elements.
The visual approach makes it easy to spot issues in context, but the interface can feel cluttered on complex pages. Results use WCAG rule codes rather than plain-English explanations.
- Price: Free
- Users: 700,000+
- Rating: 4.1 stars
3. axe DevTools -- Web Accessibility Testing
Best for: Developers who use Chrome DevTools
axe DevTools by Deque integrates directly into Chrome DevTools as a new panel. It runs the same axe-core engine but presents results in a developer-focused format with code snippets and WCAG rule references.
The free version handles single-page scans. Enterprise plans add guided testing, intelligent guided tests, and team collaboration features.
- Price: Free (enterprise plans available)
- Users: 400,000+
- Rating: 3.9 stars
4. Silktide Accessibility Checker
Best for: Teams using the Silktide platform
Silktide provides a clean, simple interface with a compliance score and clear issue categorization. The free extension works standalone, but it is designed to pair with the Silktide enterprise platform for site-wide monitoring.
- Price: Free (enterprise SaaS upsell)
- Users: 50,000+
- Rating: 4.6 stars
5. IBM Equal Access Accessibility Checker
Best for: Enterprise compliance with IBM guidelines
IBM's free checker integrates into DevTools and tests against both WCAG and IBM's own accessibility guidelines. It provides detailed reports and is particularly thorough on ARIA usage and keyboard navigation.
- Price: Free
- Users: 30,000+
- Rating: 4.9 stars
6. Lighthouse (built into Chrome)
Best for: Performance and accessibility in one audit
Lighthouse is built into Chrome DevTools (Audits panel) and includes an accessibility score alongside performance, SEO, and best practices. It uses axe-core internally but runs fewer rules than dedicated accessibility extensions.
Lighthouse is a good starting point, but dedicated accessibility tools catch more issues.
- Price: Free (built-in)
- Engine: axe-core (partial ruleset)
7. Siteimprove Accessibility Checker
Best for: Users of the Siteimprove platform
Siteimprove ranks highly in Chrome Web Store search results and provides a clear issue breakdown with WCAG conformance levels. Like Silktide, the extension is designed to feed into the enterprise platform.
- Price: Free (enterprise upsell)
- Users: 60,000+
- Rating: 3.2 stars
Which Should You Use?
For quick checks during development or content review, use a lightweight extension that does not require DevTools. Our Accessibility Checker gives you a compliance score and plain-English results in one click.
For deep technical debugging, axe DevTools or IBM Equal Access provide code-level detail in the DevTools panel.
For enterprise teams, Silktide or Siteimprove integrate with larger compliance monitoring platforms.
For comprehensive auditing with multi-page crawling, scheduled monitoring, and PDF reports, try PageAuditors -- our full web compliance platform that handles entire sites, not just individual pages.
