Web-Check - 🌐 All-in-one website OSINT tool for analysing any website

Get an insight into the inner-workings of a given website: uncover potential attack vectors, analyse server architecture, view security configurations, and learn what technologies a site is using.

Currently the dashboard will show: IP info, SSL chain, DNS records, cookies, headers, domain info, search crawl rules, page map, server location, redirect ledger, open ports, traceroute, DNS security extensions, site performance, trackers, associated hostnames, carbon footprint. Stay tuned, as I'll add more soon!

The aim is to help you easily understand, optimize and secure your website.

Often when I'm looking into a website, there's several things I always check first. None of this is hard, and can usually be done with a series of curl commands, or using a combination of online tools. But it's so much easier to have everything presented clearly and visible in one place.
