Finding accessibility issues shouldn't require context switching. You shouldn't need to navigate to a separate platform, paste a URL, wait for a scan, then manually correlate the results back to what you were building.

That friction kills momentum. It makes accessibility testing feel like a chore instead of a natural part of development.

The Blyxo Chrome Extension eliminates that friction. One click, instant results, right where you're already working.

What it does

The Blyxo Chrome Extension runs comprehensive WCAG 2.2 accessibility tests on any webpage you're viewing—whether it's your local development server, a staging environment, or a live production site.

Core features:

  • One-click scanning: Click the extension icon, get results in seconds
  • Full WCAG 2.2 coverage: Tests against all 86 success criteria across Levels A, AA, and AAA
  • Detailed issue reporting: See exactly what failed, why it matters, and how to fix it
  • Visual highlighting: Failed elements are highlighted directly on the page
  • Priority-based grouping: Critical issues surface first
  • Export options: Save reports as PDF or share via link
  • No account required for basic scans: Test any public page instantly

It's like having an accessibility expert looking over your shoulder as you build.

Why we built it

Most accessibility testing tools fall into two categories:

Category 1: Browser DevTools extensions

These are great for quick checks but limited in scope. They catch obvious issues (missing alt text, color contrast) but miss complex patterns. They're built for spot checks, not comprehensive audits.

Category 2: Enterprise platforms

These are powerful but isolated. You scan a URL, wait for results, read a report, then switch back to your code. The feedback loop is too long for active development.

The Blyxo Chrome Extension bridges this gap. It has the comprehensiveness of an enterprise platform with the immediacy of a DevTools extension.

How it works

Install and authenticate

  1. Install the extension from the Chrome Web Store
  2. Sign in with your Blyxo account (or create one—it's free for basic use)
  3. The extension is now active and ready to scan

Run a scan

Navigate to any webpage and click the Blyxo icon in your browser toolbar.

The extension immediately:

  • Analyzes the page structure
  • Runs automated WCAG tests
  • Checks keyboard navigation
  • Validates ARIA attributes
  • Measures color contrast
  • Inspects semantic HTML
  • Tests form accessibility
  • Validates heading hierarchy

Results appear in seconds.

Review results

The results panel shows:

Overview metrics:

  • Total issues found
  • Breakdown by severity (critical, serious, moderate, minor)
  • Overall accessibility score
  • WCAG conformance level achieved

Issue list:

  • Grouped by WCAG success criterion
  • Sorted by impact (critical issues first)
  • Expandable details for each violation
  • Direct links to WCAG documentation

Visual highlighting:

  • Click any issue to highlight affected elements on the page
  • See exactly which button is missing a label or which heading is out of order
  • Hover over highlighted elements to see the specific violation

Fix and re-test

Make a fix, refresh the page, click scan again. The feedback loop is instant.

This is where the extension shines for active development. You can iterate rapidly:

  1. Identify issue
  2. Make fix
  3. Verify fix
  4. Move to next issue

No waiting. No context switching. No copy-pasting URLs into external tools.

Use cases

Development

Scenario: You're building a new checkout flow. You want to ensure it's accessible before committing.

  • Open your local development server
  • Run a scan
  • Fix issues inline
  • Rescan until clean
  • Commit with confidence

The extension catches problems while the code is fresh in your mind and cheap to fix.

Code review

Scenario: You're reviewing a pull request that adds a new dashboard component.

  • Check out the branch locally
  • Navigate to the new component
  • Run a scan
  • Comment on the PR with specific accessibility issues

Reviewers can now verify accessibility as easily as they verify functionality.

Competitive analysis

Scenario: You're redesigning your product page and want to see how competitors handle accessibility.

  • Visit competitor sites
  • Run scans on each
  • Compare results
  • Identify patterns (what works, what doesn't)

Learn from others' successes and failures.

Content auditing

Scenario: Your marketing team publishes new landing pages weekly. You want to ensure they meet accessibility standards.

  • Visit each new page
  • Run a scan
  • Export report
  • Share with marketing team

No technical setup required. Anyone can run the extension.

QA testing

Scenario: You're testing a staging environment before a release.

  • Navigate through critical user flows
  • Scan each page
  • Document issues
  • Prioritize fixes before launch

Catch regressions before they reach production.

What makes it different

AI-powered recommendations

The extension doesn't just tell you what's wrong—it tells you how to fix it.

Instead of generic advice like "Add alt text to images," you get specific guidance:

Issue: Image missing alt text

Element: <img src="/product.jpg">

Fix: Add an alt attribute that describes the image's purpose:

<img src="/product.jpg" alt="Wireless headphones with noise cancellation">

Why it matters: Screen reader users won't know what this image shows. Describe what the image conveys, not just what it contains.

Context-aware, actionable, developer-friendly.

Integration with Blyxo platform

The extension isn't isolated—it's part of the broader Blyxo ecosystem.

Save scans to your dashboard:

  • Track accessibility over time
  • Compare scans across environments
  • Share results with your team

Sync with CI/CD:

  • Use the same rules as your automated tests
  • Ensure local scans match pipeline scans
  • Avoid surprises when pushing code

Unified reporting:

  • Extension scans appear alongside automated scans
  • View historical trends
  • Export comprehensive audit reports

Keyboard navigation testing

Most extensions test markup. The Blyxo extension also tests interaction.

It simulates keyboard navigation:

  • Can all interactive elements be reached via Tab?
  • Is focus visible at all times?
  • Can modals and menus be closed via Escape?
  • Does tab order match visual order?

This catches issues that markup analysis misses.

Customizable rules

Different teams have different requirements.

The extension lets you:

  • Filter by WCAG level (A, AA, AAA)
  • Focus on specific success criteria
  • Ignore known false positives
  • Apply custom rule sets

Scan for what matters to your project, not just everything.

Limitations (and how we handle them)

No tool is perfect. Here's what the extension can't do—and how we recommend supplementing it:

Limited to visible content

The extension scans what's rendered at the moment you click scan. It doesn't:

  • Trigger hover states or interactions
  • Open modals or dropdowns
  • Navigate through multi-step flows

Solution: Manually trigger interactions before scanning. Open the modal, then scan. Navigate to step 2 of the form, then scan.

Can't test authentication-protected pages

The extension runs in your browser context, so it can access pages you're logged into. But it can't scan pages that require specific user permissions or session states it doesn't have.

Solution: Use the Blyxo platform for authenticated scans. The platform can log in and crawl authenticated flows.

Automated testing has limits

The extension catches 30–50% of accessibility issues—the same limit as all automated testing.

It's excellent at:

  • Missing alt text
  • Color contrast failures
  • Invalid ARIA
  • Missing form labels

It can't judge:

  • Whether alt text is meaningful
  • Whether focus order makes sense
  • Whether the experience is coherent for screen reader users

Solution: Combine automated scans with manual testing. Use the extension for quick checks, use human judgment for nuance.

The bigger picture

The Chrome extension is one piece of a complete accessibility workflow:

  1. Extension: Test locally during development
  2. CI/CD integration: Catch issues in automated tests
  3. Platform scans: Monitor production continuously
  4. Training modules: Learn accessibility best practices

Each layer catches different issues at different stages. The extension makes the first layer—local testing—frictionless.

Because the easier you make testing, the more testing happens. And the more testing happens, the fewer issues reach production.
