xsbl is an AI-powered web accessibility scanner that checks your website against WCAG 2.2 AA and AAA criteria. It scans your rendered pages in a real browser, identifies violations like missing alt text, contrast failures, broken ARIA, and keyboard traps, and generates specific code fix suggestions for your actual markup.

How is xsbl different from accessibility overlays?

Unlike overlays that inject JavaScript and only detect about 30% of WCAG issues, xsbl scans your actual rendered DOM in a real Chromium browser. It provides real code fixes instead of cosmetic patches, works with screen readers rather than against them, and produces exportable compliance evidence accepted by courts and auditors.

Does xsbl support WCAG 2.2?

Yes. xsbl covers 90+ rules across WCAG 2.2 AA and AAA criteria, including contrast, alt text, ARIA, keyboard navigation, forms, headings, landmarks, and more. Each issue is mapped to the specific WCAG success criterion it violates.

Can xsbl create GitHub pull requests with accessibility fixes?

Yes. Connect your GitHub repository and xsbl can generate pull requests with AI-suggested code fixes for accessibility issues. You can fix individual issues or use bulk fix to address multiple issues in a single PR.

How much does xsbl cost?

xsbl offers a free tier with 1 site and 3 scans per month. Paid plans start at $19/month for Starter, $69/month for Pro with unlimited sites and 100 scans, and $249/month for Agency with white-label reports, VPAT generation, and dedicated support.

2.4.4: Link Purpose (In Context)

The purpose of each link can be determined from the link text alone or from the link text together with its programmatically determined link context.

Why this matters

Screen reader users often navigate by listing all links on a page. Multiple 'click here' or 'read more' links are meaningless without context. Link text should describe where the link goes.

Common failures

These are the most frequent ways this criterion is violated in real-world websites:

'Click here' or 'Read more' as link text
Links that say 'here' or 'this'
Image links with no alt text
Links with identical text going to different destinations

How to fix

Use descriptive link text: 'View pricing plans' instead of 'Click here'
For image links, add alt text that describes the destination
If short text is needed visually, use aria-label for a longer accessible name
Use visually hidden text to add context: 'Read more <span class="sr-only">about accessibility testing</span>'
