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.
