ADA Compliance Checker

2025

A free web accessibility scanner at freeadachecker.com. Launches headless Chromium via Playwright, injects axe-core, and scans pages for WCAG 2.2 AA violations. Stealth mode with UA rotation and consent wall auto-clicking handles sites that block bots. Falls back to an httpx HTML snapshot when navigation fails. Results are enriched with plain-language explanations for 50+ rules, then rendered into a professional PDF via WeasyPrint. Rate limited to 10 scans per IP per hour with a 1-hour scan cache. Monetized through Google AdSense. Three files, about 1,000 lines total.
