A11yProof vs WAVE: Free Scanner vs Full Compliance Platform
TLDR
WAVE (from WebAIM) is a well-regarded, free accessibility checker that lets you inspect one page at a time through a browser extension or web interface. A11yProof automates scanning across your entire site, tracks issues over time, and generates code-level fixes for what it finds. If you need a quick way to spot-check a page at no cost, WAVE is excellent. If you need full-site coverage, remediation guidance, and a compliance record, A11yProof is the better fit.

What WAVE Is
WAVE is a web accessibility evaluation tool developed and maintained by WebAIM (Web Accessibility In Mind), a nonprofit at Utah State University with a long track record in accessibility research and education. The browser extension is free, widely used, and respected in the accessibility community.
You install the extension, open a page, click the WAVE icon, and it annotates the page with icons showing errors, alerts, and structural elements. It is an excellent tool for developers learning WCAG and for auditors doing manual page reviews.
Where WAVE Falls Short for Business Use
The limitation is that WAVE is a manual, one-page-at-a-time tool. For a site with 50 pages, you run it 50 times, review 50 annotated pages, and manually document what you find. For a site with 500 pages, multiply that. WAVE does not track what changed between scans. It does not generate compliance reports. It does not suggest code fixes.
For a developer spot-checking during a sprint, this is fine. For a business owner trying to get their site compliant and stay that way, the manual overhead becomes the bottleneck.
What A11yProof Adds
A11yProof crawls your entire site and checks every page against WCAG 2.1 AA criteria automatically. When it finds a missing alt attribute, an unlabeled form input, or a color contrast failure, it does two things WAVE does not: it tracks that issue in a persistent record, and it generates a specific code fix you can apply to resolve it.
Over time, you can see whether your site’s violation count is going down, whether fixes you applied are holding, and whether new issues were introduced in your latest deployment.
The WAVE API
WebAIM offers a WAVE API for teams that want automated scanning rather than manual browser extension use. API pricing starts around $100/month for limited credits. At that price point, you’re paying for automated issue detection without fix suggestions or compliance reporting — the same tradeoffs as the free extension, but at scale.
Who Should Choose What
Use WAVE if: you’re a developer who needs a free, manual tool for spot-checking pages during development, or you’re doing a one-time accessibility audit on a small site.
Use A11yProof if: you need automated coverage across your entire site, want fix suggestions rather than just issue identification, and need a compliance record that documents what was found and remediated.
Neither option feel right?
Most small businesses pay for accessibility features they don't need. A11yProof starts at from $29/month.
Verdict
WAVE is the right tool for developers doing spot-checks and learning WCAG. A11yProof is the right tool for a business that needs continuous site coverage, fix guidance, and a compliance record. They serve different jobs — many teams use both.

Q&A
What is WAVE used for in accessibility compliance?
WAVE is used for manual accessibility checking of individual pages. Developers and auditors load a page, run WAVE, and review the annotated results. It identifies WCAG violations and best-practice issues but does not generate code fixes or produce formal compliance reports. It is most useful during development for spot-checking and learning WCAG requirements.
Q&A
Does A11yProof replace WAVE?
A11yProof replaces the automated scanning workflow that teams build around WAVE. For manual spot-checking during development, WAVE remains a useful free tool. A11yProof adds full-site automated coverage, issue tracking, fix guidance, and compliance reporting that WAVE does not provide — making them complementary rather than strictly competing.
Q&A
Which tool is better for tracking accessibility improvements over time?
A11yProof tracks issues across scans, so you can see whether violations are being resolved and whether new issues are being introduced. WAVE provides point-in-time snapshots with no historical tracking. For businesses managing ongoing compliance rather than one-time audits, A11yProof's tracking is a meaningful advantage.
