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.

Is the Website Change Alerts free?
Yes. The first workflow is free and URL-first: enter a public website URL, run the scan, and review the report before any paid monitoring or API layer.
How is this different from a generic website change alerts page?
Themerella shows evidence, confidence, issue severity, and developer-ready fixes instead of only listing detected logos or generic advice.
