📘 About WebCheck
This tool performs live checks using public APIs (DNS-over-HTTPS, RDAP, CertSpotter, ip-api, etc.). Some features (open ports, traceroute) are not possible from a browser – external links provided. All data is processed client‑side.
Responsible use only: Do not overload target servers.
WebCheck – All‑in‑One Website Information Tool
WebCheck provides comprehensive technical insights: IP address, DNS records (A, AAAA, MX, TXT, NS), SSL certificate issuer & expiry, HTTP security headers, cookies, WHOIS (registrar, creation/expiry dates), server location, robots.txt, security.txt, internal/external link count, technology hints, social meta tags, email configuration (SPF/DMARC), and DNSSEC detection.
Use Cases
- Security audits – check missing HSTS, CSP, X-Frame-Options
- SEO – verify meta tags, link structure, social cards
- Network troubleshooting – DNS, IP, redirection chain
- Domain ownership – WHOIS and RDAP info
Limitations
Due to browser security, features like port scanning, traceroute, and real load time from multiple locations cannot be performed. External services are recommended for those.
