About DomainIntel.app
DomainIntel.app is a comprehensive domain intelligence platform that provides detailed information about domains, including WHOIS data, DNS records, SSL certificates, security headers, and reputation analysis.
Our goal is to help website owners, security professionals, and IT administrators assess the security posture of domains and identify potential issues that could affect their security or reputation.
Who builds DomainIntel
DomainIntel is built and maintained by Chris Morris, a senior developer who ships small web products and developer tools. The guides and blog posts here are written from hands-on experience running domains, DNS, and TLS in production.
More of his work is at fullcycle.io, and he writes on dev.to.
Features

How It Works
DomainIntel.app uses a combination of public APIs, direct lookups, and proprietary algorithms to gather and analyze information about domains. When you submit a domain for analysis, our system performs multiple checks in parallel, compiles the results, and presents them in an easy-to-understand format.
