WCAG Accessibility Quick Scan
Paste HTML to run axe-core accessibility rules locally—ideal for component QA and pre-launch checks.
Accessibility is a launch requirement—not a retrofit
WCAG-aligned experiences expand your audience, reduce legal risk, and often improve SEO and conversion for everyone. Yet accessibility is still treated as a final QA step on many B2B sites. Automated checks will not catch every issue, but they surface high-impact problems early: images without alt text, buttons without accessible names, form fields missing labels, and structural mistakes that confuse assistive technology.
This quick scan uses axe-core—the same engine many engineering teams wire into CI—to evaluate HTML you paste into the browser. Nothing is uploaded to Cavecrack servers. Use it on navigation partials, hero modules, tables, and modals before they merge to main.
Who should use this tool?
Front-end developers validating PRs. Designers prototyping in HTML. Content marketers checking rich text exports from a CMS. Engineering managers who want a lightweight gate before external audits. Pair this with inclusive design practices on your web development engagements.
How to use it
- Copy HTML for the component or page section you want to test.
- Paste into the textarea and run the accessibility scan.
- Review violations by impact level and follow documentation links.
- Fix markup or components, then re-scan until critical issues are resolved.
Limitations
Scans run on isolated snippets without site-wide context, stylesheets, or routing. Color contrast checks may differ once global CSS loads. Keyboard traps, focus order, and screen reader announcements require manual testing. For regulated industries or public-sector clients, budget for a formal audit and remediation roadmap.
What to fix first
Prioritize critical and serious violations that block task completion: missing form labels, images without alt text on informative graphics, and interactive elements with no accessible name. Moderate issues such as color contrast often trace back to design tokens—fix them in the system, not page by page. Document patterns your team repeats so fixes compound across the site instead of reappearing every sprint.
Accessibility improvements frequently overlap with performance and SEO wins—semantic HTML and descriptive labels help everyone. If you need embedded practices across design, engineering, and QA, Cavecrack delivers accessible component libraries as part of web development programs.
Frequently asked questions
- Is this a full WCAG audit?
- No. Automated scans catch a fraction of accessibility issues. Manual keyboard testing, screen reader review, and user testing are still essential for WCAG conformance.
- Why scan a snippet instead of a full URL?
- Pasting HTML keeps the tool fast, private, and CORS-free. Test components, email templates, or CMS blocks in isolation before they ship site-wide.
- Which rules does axe-core check?
- We run WCAG 2.0 Level A and AA rules plus selected best practices—covering common issues like missing labels, invalid roles, and color contrast in supported cases.
- Can Cavecrack help remediate findings?
- Yes. Our web development practice embeds accessibility into design systems, component libraries, and CI. Contact us for a scoped audit and remediation plan.
- Does this meet ADA or Section 508 compliance requirements?
- Automated scans are one input among many. Legal compliance requires documented processes, manual testing, and often third-party audits—especially in healthcare and financial services.
