Free accessibility testing: the four tests to run

No single free tool covers WCAG. Automated checks cover 40 of the 55 WCAG 2.2 A and AA criteria, fully or partly; the rest needs a person. These four tests together give a sound first audit, at no cost.

TestWhat it findsWhat it missesFree tool
Automated scan of the rendered pageMissing alt text and labels, contrast, ARIA errors, focus and keyboard problems — on the page as it renders, scripts and third-party widgets includedAnything that needs judgment: whether alt text is accurate, whether the page makes senseThe free scan above, one page in 10–30 seconds
Color contrast checkWhether a text and background pair, or an icon or border, meets WCAG 1.4.3 and 1.4.11Text over images and states you don’t think to testColor contrast checker
Keyboard testWhether every link, button and form works with Tab, Enter, Space and Escape, focus is visible and nothing traps itHow a screen reader announces thingsUnplug the mouse and use the page — no tool needed
Screen reader testWhether names, headings, announcements and reading order make sense when heardVisual problems such as contrastFree: VoiceOver (Mac, iPhone), Narrator (Windows), NVDA (Windows), TalkBack (Android)

Questions

How do I test my website for accessibility?

Paste a page’s URL above for an automated check against WCAG 2.2 Level A and AA. Automated checks cover 40 of the 55 criteria, fully or partly, so finish with a manual pass: use the page with only a keyboard, try a screen reader, and review the criteria a tool can’t judge, such as whether alt text describes the image.

Is a free accessibility checker the same as an accessibility audit?

Not quite. An automated check is the first part of an audit: it finds the issues code can detect, on every page you scan. A full audit adds the manual review above, done by a person.

Is ADAGuard’s accessibility scanner really free?

Yes. The free plan gives you unlimited single-page scans (no crawling) of one website, with no credit card required. You get the same 100+ accessibility rules as the paid plans, including fix guidance and WCAG criterion mapping — fix an issue and rescan the same page as many times as you want.

What does the free accessibility scanner check?

Missing alt text, low color contrast, unlabeled form fields, missing keyboard focus, poor heading hierarchy, invalid ARIA attributes, missing page language, empty link text, missing skip navigation, auto-playing media and more — all mapped to WCAG 2.2 criteria.

Do I need to create an account?

No. You can scan any public URL straight away. Your score, issue counts and the top issues are shown right away. To save the full report, track progress over time and rescan that page, create a free account (no credit card required).

What free tools can I use to test my e-commerce site for WCAG violations?

Start with a free scan of a product page, a collection page and the cart: e-commerce failures usually come from apps — pop-ups, review widgets, cart drawers — that only appear once the page has rendered, so the scan has to run in a real browser. Then check colors with the free contrast checker, and walk through a purchase with only a keyboard and with a free screen reader.

Which accessibility tools support keyboard navigation and screen reader testing?

The scan checks keyboard access automatically — focus that is visible, not trapped and not hidden behind sticky headers, controls that can be reached and named — and checks what a screen reader is given: names, roles and states from the browser’s accessibility tree. Hearing the page still needs a screen reader; VoiceOver, Narrator and NVDA are free.

How does ADAGuard avoid false positives?

It judges what users actually get. Names and visibility come from the browser’s accessibility tree, the same source a screen reader uses, and visual findings such as contrast and focus are confirmed on the rendered pixels, so text that renders fine isn’t reported. The checks are tested against the W3C’s ACT rules test cases. No automated tool is perfect, which is why every finding shows its element to review.

Do I need a Chrome extension to check accessibility?

No. ADAGuard runs in the cloud: paste a URL and it loads the page in a real browser on our side, so there is nothing to install. Paid plans can also crawl many pages, scan on a schedule and check each GitHub pull request — things an extension running on one tab can’t do.

How much does an automated accessibility scanner cost?

ADAGuard’s single-page scan is free. Paid plans add crawling and monitoring: Starter is $49 a month (50 pages per scan), Professional $129 (500 pages, pages behind a login, API, VPAT) and Business $249 (1,000 pages, 10 websites, white-label reports).

Can I scan password-protected pages for free?

Scanning pages behind a login is on the Professional plan ($129/mo) and above. The free plan scans public pages only.
