Accessibility Audit
WCAG 2.1 AA compliance audit using axe-core.
Accessibility audits check your site against WCAG 2.1 Level AA guidelines using axe-core — the industry-standard accessibility testing engine. Each violation includes the impact level, affected elements, and an AI fix prompt.
#Speed
Takes 5-15 seconds. Uses Playwright to render your page and inject axe-core for analysis.
#Impact Levels
| Impact | Description | WCAG Level |
|---|---|---|
| Critical | Blocks users completely — keyboard traps, missing form labels | A |
| Serious | Significant barrier — missing alt text, low contrast text | A |
| Moderate | Annoying but not blocking — redundant links, missing landmarks | AA |
| Minor | Best practice issues — duplicate IDs, unnecessary ARIA | AAA |
#What It Checks
axe-core tests for 100+ rules including:
Images — Alt text on all meaningful images
Forms — Labels, field descriptions, error messages
Color — Contrast ratios between text and background
Keyboard — All interactive elements reachable via keyboard
ARIA — Correct use of ARIA roles, states, and properties
Structure — Proper heading hierarchy, landmarks, lists
Tables — Table headers, captions, scope attributes

}#Chrome Detection
Vergate auto-detects system Chrome (/usr/bin/google-chrome) before falling back to Playwright's bundled Chromium. If you're self-hosting, installing Chrome gives faster startup.
