What is DomainPro.io?
DomainPro.io is a free, all-in-one platform for anyone working with domain names. Whether you invest in domains professionally, need to find the right name for a new product, or want to understand what a domain might be worth before buying or selling, everything here runs on real data and is completely free to use.
Our domain discovery engine checks thousands of names daily across six popular extensions — .com, .net, .org, .io, .ai, and .co — and verifies each one against the official RDAP registry servers in real time. If we list a domain as available, it genuinely is. No guesswork, no stale databases.
The valuation tool uses an AI model trained on hundreds of thousands of historical aftermarket transactions. You get three separate estimates — auction, marketplace, and brokerage — so you can understand the range a domain might trade for depending on the sales channel. Bulk appraisals handle up to 2,560 names in a single request.
Our whois lookup queries registry and registrar RDAP servers directly, returning registrar details, creation and expiration dates, nameservers, EPP status codes, DNSSEC signing, and abuse contact information. For domain investors evaluating acquisition targets, this context is essential.
The sales tracker scrapes publicly available transaction data from sources like NameBio, DNJournal, and Sedo, giving you a running picture of what domains are actually selling for across the aftermarket. Understanding recent comparable sales is one of the most reliable ways to gauge a domain's fair market value.
