web-check

web-check is an all-in-one OSINT dashboard for analyzing any website's infrastructure, security posture, and technology stack from a single URL. It pulls DNS records, WHOIS data, SSL certificate details, HTTP headers, server location, open ports, linked pages, social tags, and performance metrics into a clean visual interface. Security-specific checks include HTTP security headers, cookie flags, content security policy analysis, and technology fingerprinting via Wappalyzer signatures. With over 32,000 GitHub stars, it is one of the most popular web reconnaissance tools on GitHub. Deployable as a Docker container for private use or accessible through the hosted instance. Built with TypeScript and designed to give you a complete picture of a target website in seconds rather than running five separate tools.
