Deep Whois is an enhanced Whois lookup tool for iOS, macOS, Linux, FreeBSD, Windows, and other platforms. Compared with the built-in system whois, it focuses on more comprehensive domain, IP, ASN, RDAP, and ENS queries. Using its own redundant Whois infrastructure, it automatically follows Whois server chains and returns the final consolidated record, reducing manual lookups and information noise.
Feature-wise, it covers more than 1,500 top-level domains and over 9,000 second-level domains, and supports IPv4, IPv6, ASN, internationalized domain names (IDN), RDAP, as well as .eth ENS domains and Ethereum address lookups. Advanced features include Whois History, which lets you view changes in domain ownership and registration data; Notifications for tracking domain expirations and Whois data changes; Privacy Shield for hiding the source IP of queries; and Color Whois, which provides colored themes on iOS and in the terminal for better readability.
The product is available as iOS, Terminal, and Web versions. The terminal version supports macOS, Linux, and FreeBSD, while Windows also has documentation for Command Prompt and PowerShell usage. Its ecosystem integrations mainly revolve around Whois, RDAP, TLD registries, ENS, and IP/ASN data sources; there is no visible API, SDK, plugin, or self-hosting capability. In terms of documentation, the website provides installation guides, feature docs, and multi-platform setup tutorials covering Ubuntu/Debian/Kali, macOS, Windows, and other scenarios, making it beginner-friendly.
Pricing is not very transparent. The site only states that some features are included with the app download or a one-time purchase, while Whois History, notifications, Privacy Shield, ENS, and other capabilities are part of a recurring subscription. Specific prices and plans are not disclosed. Its open-source or closed-source status is also unclear, and information about APIs/SDKs and enterprise-level support is missing. Based on the feature table, the Web version also appears weaker than the iOS and terminal versions.
Deep Whois is suitable for domain investors, security researchers, developers, operations teams, and teams that need to manage domain expirations. If you only perform occasional Whois lookups, the system whois tool or ICANN Lookup is sufficient; if you need historical records, monitoring, and a multi-platform terminal experience, Deep Whois offers more value. Access and payment availability from mainland China are not mentioned, so they are considered unknown. Alternatives include DomainTools, WhoisXML API, SecurityTrails, official RDAP services, and similar tools.
