Why Use Our Free Domain Tools?
Our domain tools are powered by RDAP (Registration Data Access Protocol), the modern replacement for traditional WHOIS. This means you get accurate, real-time data directly from domain registries—not cached or outdated information.
Whether you're a domain investor researching potential acquisitions, an SEO professional analyzing competitor domains, or a business owner verifying domain ownership, our tools provide the data you need instantly and for free.
What is RDAP?
RDAP (Registration Data Access Protocol) is the successor to WHOIS, providing standardized access to domain registration data. Unlike traditional WHOIS, RDAP returns structured data in JSON format, making it more reliable and easier to parse.
Our tools support major TLDs including .com, .net, .org, .io, .dev, .app, and .co. All queries are made directly to authoritative registry servers, ensuring the most accurate and up-to-date information available.
