Free WHOIS Node.js Client

freewhois is a Node.js client designed for retrieving WHOIS information by querying the IANA RDAP DNS database. It provides a free and programmatic way to perform domain lookups. The current stable version is 1.3.8. While a specific release cadence isn't detailed, the TLD list is noted as being updated regularly (last on 11/2/2025), suggesting ongoing maintenance. Its key differentiator is leveraging the IANA RDAP database directly, offering a straightforward, free API for WHOIS queries without relying on external, potentially rate-limited, third-party services. It supports both programmatic use in JavaScript/TypeScript projects and includes a command-line interface for quick lookups, making it versatile for both developers and system administrators.
