As answered by people managing CodeClimate and WCAGCheck.app.
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.
