AccessibilityChecker.org vs ADA Scanner

If you're searching for a way to check your website's accessibility, you've probably come across AccessibilityChecker.org. It's one of the more visible tools in this space, and for good reason — they've built a solid platform with recurring scans, team dashboards, and a Chrome extension.

We built ADA Scanner for a different reason. Not everyone needs ongoing monitoring. Some people just need to know: does my website pass, and if not, what do I fix?

Here's an honest comparison of the two tools and who each one is for.

The core difference

AccessibilityChecker.org is a subscription monitoring platform. You pay monthly or annually for a domain license. It crawls your site every 7 days, tracks issues over time, and gives your team a dashboard. If you have developers actively working on accessibility improvements across a large site, that ongoing visibility is useful.

ADA Scanner is a one-time compliance check. You paste a URL, get a score in 30 seconds, and can buy a detailed report with AI-generated fix instructions for $19 (single page) or $49 (full site, up to 10 pages). No account. No subscription. No commitment.

Side-by-side

When AccessibilityChecker.org makes more sense

If you're a development team actively remediating a large website over months, a subscription tool that tracks your progress makes sense. You want to see issues go down over time. You want alerts when new pages break accessibility. You want multiple team members looking at the same dashboard.

That's a real use case, and AccessibilityChecker.org handles it well.

When ADA Scanner makes more sense

You don't have a development team. Or you do, but they're busy and you just need a clear answer: what's broken and how do I fix it?

Maybe you're a government IT manager with 31days until the ADA Title II deadline and you need to hand your web vendor a list of specific fixes. Maybe you run an e-commerce store and got a demand letter. Maybe you're a freelancer who wants to show a client their accessibility gaps before pitching remediation work.

In all of these cases, you don't want a dashboard you have to log into every week. You want a report you can act on today.

That's what we built. Paste a URL, get your score, buy the report if you need the details. The report includes every failing element with its exact location in your code, an AI-generated explanation of what's wrong and why it matters, specific fix instructions with code examples, and a compliance checklist showing what you pass and fail.

The AI difference

This is where the two tools diverge most. AccessibilityChecker.org gives you the issue, the failing element, and a generic fix description. That's useful if you already know WCAG well.

ADA Scanner runs your results through AI analysis that writes fix instructions specific to your site. If you have 13 images missing alt text, it doesn't just say "add alt attributes." It shows you the exact images, explains what each one should say based on context, and gives you the corrected HTML. If you have 57 color contrast failures, it identifies the CSS values causing them and tells you what to change them to.

The goal is a report that a non-technical person can hand to any developer and say "fix these things" — and the developer knows exactly what to do without having to interpret WCAG documentation.

What about free tools?

WAVE, Lighthouse, and axe DevTools are all free and genuinely good. If you're a developer who knows WCAG, these tools give you the raw data you need.

The gap is interpretation. Free tools tell you what failed. They don't tell you why it matters,how to prioritize, or exactly how to fix itin plain English. That's the gap both AccessibilityChecker.org and ADA Scanner fill — we just do it differently (ongoing monitoring vs one-time actionable report).

Bottom line

Use AccessibilityChecker.org if you need continuous monitoring and have a team working on accessibility long-term.

Use ADA Scanner if you need a clear, actionable compliance report right now — especially if a deadline is approaching or you just want to know where you stand without signing up for anything.
