Website

What it is

Web-Check takes a URL and runs a batch of lookups against it, covering DNS records, SSL certificates, HTTP headers, server location, open ports, detected technologies, and security settings. Results are shown together on one page, with optional API keys unlocking extra checks such as PageSpeed and Safe Browsing. Sysadmins, security researchers, and site owners use it to spot weak configurations and learn how a website is built. It can be used on the hosted site or deployed yourself with Docker or a one-click host.
