If you've ever gotten an email threatening a lawsuit over your website's accessibility, or you just want people using screen readers to actually be able to use your product, you need an accessibility audit. The legal term for the standard is WCAG (Web Content Accessibility Guidelines), and most countries now have some version of a law that requires public-facing websites to meet it — the EU's Accessibility Act, the US's ADA and Section 508, Canada's AODA, the UK's Equality Act. The problem is that checking WCAG compliance by hand, page by page, doesn't scale. That's what the tools below automate: they crawl your site, flag the exact elements that fail (missing labels, low-contrast text, buttons a screen reader can't reach), and in several cases suggest or generate the code fix. None of them fully replace a human audit for legal certainty on complex cases, but they catch the bulk of real-world violations in minutes instead of weeks. Here are 7 real tools, all live in production, ranked from full-service enterprise platforms to free browser extensions.
1. Eye-Able
Eye-Able is the most complete option here: it combines automated scanning, an AI assistant that explains errors and suggests fixes, and actual human audits performed by people with disabilities. It's used by 20,000+ websites including Red Bull and UEFA, and it's BSI-certified.
Pricing: No public pricing — 14-day free trial, then a custom quote after a sales call.
The short version: if you're a large European company that needs to prove compliance with real human review behind it, not just an automated scan, Eye-Able is built for that. If you want self-serve pricing you can see before talking to sales, look elsewhere on this list.
2. GetWCAG
GetWCAG scans a site page by page, including pages behind a login, and offers an accessible entry price compared to enterprise compliance platforms. It also sells a manual audit with an ACR (Accessibility Conformance Report) as a separate paid add-on for teams that need a legally defensible document.
Pricing: Free (10 page scans, no card). Then Basic $19/mo (250 pages), Starter $99/mo (2,000 pages), Growth $399/mo (6,000 pages), Business $999/mo (12,000 pages), Enterprise on request.
The short version: good middle ground — a real browser-based scan engine, scheduled monitoring, and a $19/mo entry point that undercuts most compliance-focused competitors. The jump to Business/Enterprise gets expensive fast for high-page-count sites.
3. DevAlly
DevAlly plugs directly into your GitHub workflow and blocks accessibility regressions before they reach production, instead of catching them after the fact. It also generates VAT/ACR-style reports for legal review.
Pricing: Free (5 audits/week, 1 product, 3 seats). Growth and Compliance tiers on request, the latter including a manual expert audit.
The short version: the best fit if your priority is stopping accessibility bugs at the CI/CD stage rather than auditing an already-live site. Pricing beyond the free tier isn't public, so budget-conscious teams will need to talk to sales first.
4. A11yFlow
A11yFlow renders your pages in a real Chromium browser, which means it also catches issues introduced by client-side JavaScript, not just static HTML. It ships a CLI and an MCP server, so AI coding agents can run scans directly.
Pricing: Free (25 scans/month) up to £149/mo (25,000 scans), Enterprise on request.
The short version: a solid developer-first pick if your app is JS-heavy (React/Vue SPAs) since a lot of scanners miss what only renders after the JS runs. Multi-page crawling and scheduled scans are locked to the paid tiers.
5. A11y Pulse
A11y Pulse runs a daily automated scan of your whole site instead of a one-off audit, and alerts your team the moment a new violation appears — useful because sites drift out of compliance quietly as content and code change.
Pricing: Starter $19/mo (50 pages, 1 site), Growth $49/mo (200 pages, 3 sites), Comprehensive $159/mo (1,000 pages), Scale $499/mo (10,000 pages). 1-month free trial, no card required.
The short version: the tool is upfront that it only catches roughly 30-50% of real WCAG issues automatically — which is honest, and a useful reminder that every tool on this list has that same ceiling. Good for agencies managing several client sites thanks to white-label PDF reports.
6. A11yInspect
A free browser extension (plus a VS Code extension and an ESLint plugin) that runs 600+ checks covering WCAG, Section 508 and regional standards like the EU's EN 301 549, with a claimed false-positive rate under 1%.
Pricing: Free extension with unlimited page testing. Pro $120/year adds a dashboard, screenshots and downloadable audit reports (30-day trial).
The short version: the best option if you want a genuinely free, unlimited scanner for day-to-day development, with the option to pay later once you need shareable reports.
7. A11yEngine
A completely free Chrome extension built on axe-core plus 43 additional heuristics, with fix suggestions tailored to React, Vue, Next.js and Tailwind. All processing happens locally in your browser.
Pricing: Free, no paid tier at all.
The short version: if you just want a no-strings-attached scanner to run while you're coding a React or Vue app, this is it. There's no paid tier, which is great for your wallet but worth noting when you think about how the project sustains itself long-term.

None of these tools will get you 100% legal certainty on their own — automated scanning typically catches somewhere between a third and half of real WCAG issues, and the rest (things like whether alt text actually makes sense in context) still need a human reviewer. But wiring one of these into your workflow, even the free ones, is the difference between finding out about an accessibility problem from a scan report or from a legal complaint.
