Best ADA Website Accessibility Scanners in 2026: A Comparison for Public Entities

With ADA Title II compliance deadlines approaching — April 2026 for larger entities, April 2027 for smaller ones — school districts, cities, and counties need to choose a website accessibility scanner. There are dozens of options ranging from free browser extensions to enterprise platforms costing tens of thousands of dollars. Here is how the most common tools compare for public entities.

What to look for in a scanner

Before comparing specific tools, here is what matters most for schools and governments:

• WCAG 2.1 AA coverage — The DOJ requires conformance with this specific standard. Your scanner needs to test against it.
• Plain-English reporting — Technical axe-core output is useful for developers but not for the administrator or superintendent who needs to understand the results.
• Ongoing monitoring — A one-time scan is not enough. Websites change constantly, and new content introduces new issues.
• Affordable pricing — Public entities have limited budgets. A tool that costs more than the remediation itself is not practical.

AccessEval

Best for: K-12 districts, small cities, counties, and special districts with limited budgets.

AccessEval is purpose-built for schools and local governments. It scans with Playwright and axe-core, translates every issue into plain English, and provides CMS-specific fix instructions for platforms like WordPress, Finalsite, and Squarespace. Pricing is simple and public: $99/year for monthly scans of up to 100 pages, $299/year for weekly scans of 500 pages with compliance documentation, and $599/year for 2,000 pages with CMS-specific guidance and vendor-shareable reports.

Strengths: Purpose-built for public entities, plain-English reports, affordable pricing, accessibility statement generator, free scan with no signup.

Limitations: No JavaScript overlay remediation, no managed services.

WAVE (WebAIM)

Best for: Quick, one-off manual checks of individual pages.

WAVE is a free browser extension from WebAIM that overlays accessibility errors directly on the page. It is excellent for developers who want to visually inspect a single page. However, it does not crawl your site, does not provide ongoing monitoring, and does not generate reports suitable for stakeholders. For a district with hundreds of pages, manually checking each one with WAVE is impractical.

Strengths: Free, visual feedback, well-established, great for developers.

Limitations: Manual one-page-at-a-time use, no site-wide scanning, no monitoring, no exportable reports.

axe DevTools (Deque)

Best for: Development teams building accessible websites from scratch.

Deque’s axe is the industry-standard accessibility testing engine — it powers many other tools, including AccessEval. The free axe DevTools browser extension is excellent for developers who can interpret technical output. Deque also offers axe Monitor for site-wide scanning, but enterprise pricing typically starts at several thousand dollars per year.

Strengths: Industry-standard engine, highly accurate, developer-friendly.

Limitations: Technical output not suitable for non-developers, enterprise pricing for monitoring features.

Siteimprove

Best for: Large organizations with comprehensive digital governance needs.

Siteimprove is a full digital governance platform that includes accessibility, SEO, content quality, and analytics. It is widely used by universities and state governments. However, it is priced for enterprise use — annual contracts typically start at $10,000 or more. For a small district or municipality, the platform offers far more than needed at a price point that is difficult to justify.

Strengths: Comprehensive platform, strong enterprise reporting, well-known in higher education.

Limitations: Enterprise pricing, complex setup, overkill for small entities.

AudioEye

Best for: Organizations that want a vendor to manage remediation.

AudioEye combines automated scanning with a JavaScript overlay that attempts to fix certain issues client-side. This approach is convenient but controversial — accessibility advocates have raised concerns about overlay tools interfering with assistive technology. Pricing is not public but typically starts at several thousand dollars per year.

Strengths: Managed remediation, overlay fixes some issues immediately.

Limitations: Overlay approach is controversial, pricing not transparent, does not fix underlying code.

Summary comparison

For K-12 school districts and small municipalities with limited budgets, the practical choice comes down to: use free tools like WAVE for spot checks, and pair them with an affordable monitoring tool like AccessEval for site-wide, ongoing compliance. Enterprise tools like Siteimprove and AudioEye make sense for large organizations with dedicated accessibility teams and corresponding budgets.

The most important step is to start. Run a free scan with AccessEval to see exactly where your website stands — it takes under two minutes, and no signup is required.
