What is Web-Check?
Web-Check is an open-source OSINT tool that technically examines any website in a single pass. Enter a URL and you get structured information on IP address, SSL certificate, DNS records, open ports, server location, security headers, performance metrics and the technologies in use. Everything appears in a single dashboard, with no need to consult multiple specialist services in parallel.
The project is developed on GitHub and can be self-hosted. Docker, Netlify and Vercel are officially supported.
Core features
- SSL and DNS analysis: Validate certificates, check expiry dates, and inspect DNS records for misconfigurations
- Server infrastructure: IP information, server geolocation and open ports at a glance
- Security configuration: Systematic evaluation of HTTP security headers and related settings
- Technology detection: Identify frameworks, CMS platforms or analytics services in use
- Performance metrics and trackers: Measure load times and detect embedded tracking scripts
- Self-hosting: Deploy via Docker, Netlify or Vercel without depending on a central service
Who is Web-Check for?
The tool is aimed at security professionals, penetration testers and IT administrators who need a quick overview of a domain's attack surface. Web developers also use it to check their own domains for overlooked misconfigurations.
Users with little networking background may struggle to interpret the results. A flag on the security headers does not indicate whether a gap is actually exploitable. The tool provides raw data and findings, not recommendations for action.
Context & alternatives
Web-Check belongs to the category of website reconnaissance tools. Comparable services such as Shodan, SecurityHeaders.com and MXToolbox each cover specific areas. Web-Check combines these perspectives in one interface, but loses the depth of specialised tools in the process.
Anyone who needs regular, automated security scans with reporting functionality will hit limits here. For manual first-pass analysis and ad-hoc audits, no other freely available tool delivers this breadth of information in a single view.
