Accessible Color Contrast Checker

Position color contrast as an accessibility fix chain: scan a page first, then repair low contrast UI states.

Safe public URL scan. Results include technology evidence, SEO checks, security headers, accessibility basics, and a developer fix list.

How it works

The scanner fetches the public page, follows a limited redirect chain, collects headers/resources/HTML, applies self-owned detection rules, checks SEO/security/accessibility/performance signals, and returns evidence-backed fixes.

Private IPs, localhost, file URLs, and internal hostnames are blocked to reduce SSRF and abuse risk.
