WebCheck: inspect the public signals a website exposes

web-check.xyzPermalink

WebCheck banner with the project name in green, the text “On-demand OSINT tool for exploring website data,” and a globe icon protected by a shield.

WebCheck brings publicly exposed domain information into one interface: DNS, TLS certificates, HTTP headers, subdomains, detected technologies, and potential threat-list matches. It offers 44 checks and can also examine redirects, trackers, and email configuration.

The results provide a useful starting point for surface-level checks, not a substitute for a thorough audit: some data, such as vulnerabilities linked by Shodan, depends on external sources. The project is open source, can be self-hosted, and provides an API.
