Web Check-The most comprehensive website detection tool

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.

Motivation

Often when you're looking into a website, there's several things you always initially check. Think: Whois, SSL chain, DNS records, tech stack, security protocols, crawl rules, sitemap, redirects, basic performance, open ports, server info, etc. None of this is hard to find with a series of basic curl commands, or a combination of online tools. But it's just so much easier to have everything presented clearly and visible in one place :)

Note that not all checks will work for all sites. Sometimes it's not possible to determine some information, and the demo instance has some limitations imposed by Netlify for the lambda functions.
