Enter a URL and A11y Check samples representative pages, audits them against WCAG 2.2 and KWCAG 2.2, and produces a report that shows what to fix and how. Automation is only the start: an evaluator adds manual verdicts on top, so the result is fit for real conformance reviews. It is free, and all of the code is public.
알리첵 (Allycheck)
A11y Check
"a11y" is the standard numeronym for accessibility, counting the 11 letters between the a and the y. Read aloud in Korean it becomes "alli" (알리), which happens to sound exactly like the Korean verb for "to make known". Add "chek" (check) and you get our Korean name, 알리첵.
알리첵 — we make accessibility issues known, and check them off.
There are plenty of accessibility checkers. Most cover only the international standard or only the Korean one, and even the good ones leave you writing the actual report from scratch. We wanted a tool that evaluates both standards at once, produces a submission-ready report, and lets anyone inspect the judgment logic in code. So we built it.
This service is built and run by the web manager at Daegu Cyber University.
Daegu Cyber University was founded on the spirit of "Love, Light, and Freedom" and has specialized in special education, rehabilitation, and welfare. When you run the web for a university whose mission is widening the door of learning for students with disabilities, accessibility stops being a compliance item and becomes the obvious thing to do. Allycheck is a tool that makes that obvious thing easy for other organizations and developers too.
About Daegu Cyber University ↗See where your site stands in numbers, and hand the report to management or your vendor as a share link or PDF. Turn on scheduled scans and it watches your site daily.
Every violation comes with the page URL, CSS selector, offending code, and a fix example. Export an AI fix request file and paste it into Claude or ChatGPT to get corrected code.
Automation lays the groundwork; anything it can't judge is left as a manual check with testing instructions. Record verdicts and notes to complete a combined automated + manual report.
We didn't invent our own criteria. We follow what W3C and the Korean national standard define.
W3C's official website evaluation methodology. Scoping, exploration, representative sampling, auditing, and reporting follow this procedure, with export compatible with the W3C Report Tool.
The international guidelines. Each of the 55 A/AA success criteria is shown as passed, violated, or needs manual review.
The Korean guidelines (KS X OT0003), presented as the same 33-item matrix used in domestic certification audits.
Samples pages from your sitemap and internal links, then runs ~90 axe-core rules: alt text, color contrast, keyboard access — the things a machine can judge with confidence. Pages are re-checked at mobile width, and same-origin iframes are audited too.
Evaluators record per-criterion verdicts and observations on top of the automated results. Add site details and an executive summary and it becomes the print/PDF report.
Admin screens behind login and bot-blocked sites are out of a server's reach, so the extension audits them right in your browser and merges results into your site report. It also ships on-page tools: color-blindness simulation, focus-order overlay, a contrast eyedropper.
Verified domains get an SVG badge showing the latest compliance rate, ready to embed.
Turn it on and your site is scanned daily. If compliance drops or new violations appear, you get an email; the dashboard shows the trend over time.
Automated tools can only find a portion of accessibility issues. We state that limit in the report itself, not in fine print, and mark everything requiring human judgment as a manual check with testing instructions. Our automated results alone cannot support a conformance claim — and you should be skeptical of any tool that says otherwise.
The scan engine, the WCAG/KWCAG mapping, and the Korean remediation guides are all Apache-2.0 licensed. If a verdict looks wrong, open the code and check the reasoning — or fix it and send a pull request.
