As answered by people managing WCAGCheck.app and CodeBeautify.
WCAGCheck.app's answer
Most accessibility tools require a live URL, a browser extension install, or a CI pipeline setup. WCAG Accessibility Checker works with a paste — you can check any HTML snippet, a template, or a component in isolation before it's even deployed. It also gives plain-English fix instructions, not just error codes that require a WCAG spec lookup.
WCAGCheck.app's answer
WAVE and Lighthouse require a live URL. axe requires a browser extension or test runner integration. WCAG Accessibility Checker requires nothing — paste HTML, click run, get results. It's the fastest way to do a spot check during development or review. Zero friction means developers actually use it.
WCAGCheck.app's answer
Frontend developers and UI/UX designers who need to verify accessibility compliance without setting up a full audit pipeline. Also useful for accessibility auditors doing manual reviews of client code, and product managers verifying components before launch.
WCAGCheck.app's answer
Accessibility audits are expensive — a professional audit can cost hundreds or thousands of dollars. A lot of that cost covers things a script can catch in milliseconds. I built this so developers can fix the obvious issues before they ever reach an auditor, making both the developer's and auditor's job easier.
WCAGCheck.app's answer
HTML5, vanilla JavaScript, CSS3. Accessibility rules are implemented as pure JavaScript functions that parse and traverse the DOM representation of the pasted HTML. No external APIs, no backend, no dependencies.
WCAGCheck.app's answer
WCAG Accessibility Checker is a free tool used by individual developers, designers, and accessibility auditors. It has no paid tiers or enterprise customers.
