WCAG 2.1 audit · ADA compliance · fix code included
Paste a URL and we crawl your whole site against 45+ WCAG 2.1 checks across 11 areas: images, links, forms, headings, contrast, ARIA, and more. Every issue comes mapped to its success criterion (A / AA / AAA) with severity, the offending HTML, and ready-to-paste corrected code. Export the full report as PDF, XLSX, or CSV. Free, no signup, no email gate.
Scans up to 30 pages per run · static analysis catches most machine-detectable issues · built for the ADA Title II 2026 deadline and the European Accessibility Act
How the accessibility scan works
No black box. Here is exactly what happens when you click Scan my site. The engine runs the same deterministic checks an accessibility consultant would run by hand, maps every failure to its WCAG 2.1 success criterion, and writes the fix code for you.
Top of this page. Any domain or full URL works: example.com, https://example.com/, blog.example.com/post/. The URL you enter becomes the seed this website accessibility audit tool starts from.
Before crawling we read /sitemap.xml and follow one level of sitemap index files, then merge those URLs with the crawl so this full site accessibility checker reaches pages that internal links alone might miss.
Starting from the seed we follow internal links breadth-first, up to 30 pages per run. The whole wcag 2.1 audit online runs on a plain fetch + parser engine (no headless browser), fast and shared-hosting friendly, with SSRF-safe fetching.
For every page we inspect each image, link, button, form field, heading, table, landmark, and ARIA attribute against the full rule set, and record the exact offending HTML for each hit.
We fetch your stylesheets and compute the true contrast ratio of text against its background, checking every pair against both AA (4.5:1) and AAA (7:1) thresholds, not a guess from inline styles.
Each issue is mapped to its WCAG success criterion and level, assigned a severity, and paired with a corrected, ready-to-paste HTML snippet: generated labels, suggested alt text, compliant color values.
An overall compliance score and verdict, per-area scores across 12 areas, and every check grouped as fail / pass / neutral with example occurrences and the pages they appear on. Exactly what you need from an ada compliance scanner.
One click for a branded PDF summary, a multi-sheet XLSX with every recorded occurrence, or a flat CSV for your issue tracker. No email gate on any of them.
How it runs
Sensible defaults handle 95% of sites with zero configuration — just paste a URL and scan. The crawler is intentionally lightweight so it runs anywhere and never hammers your server.
Built with strict SSRF protection, a small concurrency window, a hard page cap, and a fixed time budget so a single run always finishes cleanly.
Pages per run
30 by default · hard cap 100
Enough for a full small-to-mid site in one pass. Scan a specific section by seeding the run from a deeper URL.
Sitemap seeding
Auto from /sitemap.xml
Reads your sitemap and follows one level of sitemap index files, then merges those URLs into the crawl.
Concurrency
4 parallel fetches
A small, polite request window that stays friendly to shared hosting while keeping the scan quick.
Time budget
~4 minutes
A hard time ceiling so a single run never hangs. Large sites are truncated cleanly at the page or time cap.
Engine
Plain fetch + HTML parser
No headless browser. Static analysis catches the large majority of machine-detectable WCAG 2.1 issues.
Safety
SSRF-protected
Private-IP fetches (127.0.0.1, 10.x, 192.168.x, link-local) are blocked at the server level. Public URLs only.
What you get
Not just a list of problems. A prioritised, criterion-mapped report with the corrected code for each issue and clean exports for developers, clients, and auditors — free, no sign up, no daily limits.
Images, links, forms, headings, contrast, tables, landmarks, ARIA and more across 12 areas — every issue mapped to its success criterion and level (A / AA / AAA) with severity.
Each issue shows your actual HTML and a corrected, ready-to-paste version: generated labels, suggested alt text, compliant color values.
Branded PDF summary for stakeholders, multi-sheet XLSX with every occurrence, flat CSV for your issue tracker. No email gate.
An overall compliance score and verdict plus per-area scores across 12 report areas, so you know exactly where to start.
Seeded from your sitemap plus a breadth-first internal-link crawl, up to 30 pages per run. See which pages carry the most issues at a glance.
ADA Title II requires WCAG 2.1 AA for US public entities by April 2026; the European Accessibility Act is already in force. Find your gaps now.
While the scan runs
The loading screen is a real-time window into the audit — a stage tracker that lights up as the engine moves from fetching pages to scoring the report, plus live accessibility tips while you wait.
Fetching pages → Checking images → Checking links & buttons → Checking forms → Measuring contrast → Validating ARIA → Scoring report. Each step lights up as the engine reaches it, so you always know what is happening.
Rotating tips explain the issues we look for — missing alt text, low contrast, skip links — so the wait doubles as a quick WCAG refresher.
When the crawl ends, the report opens on an overall score ring and per-area breakdown, with every issue ready to expand and export.
What we check
The same areas an accessibility consultant would walk through, automated. Each area gets its own score in the report so you can triage the biggest wins first.
Alt text on images, SVGs, image buttons and image maps.
Captions, autoplay, refresh, zoom blocking.
Justified text, tiny fonts, very long paragraphs.
Accessible names, vague link text, fake buttons.
Labels, placeholder misuse, grouped controls.
Skip links, iframe titles, tab order, named menus.
Page titles, heading hierarchy, landmarks, valid markup.
Main, navigation, banner, footer and search landmarks.
Header cells, captions and scope on data tables.
Text color vs background, AA and AAA thresholds.
Page language declaration and document links.
Valid roles, working references, states, tabs, hidden content.

Built for makers
Every scan runs once per request. The crawl and report live in your browser for the session and disappear when you close the tab. We never persist your scanned URL or its results on our servers, and exports are generated client-side.
