Questions & Answers

As answered by people managing WCAGCheck.app and GitHub Hovercard.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

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.
