Every domain has a history. What it pointed to, who owned it, what it ran. Most of that history disappears the moment it changes. We've been keeping it. DNS, WHOIS and tech stack changes, archived every day, forever.
Request access →The web's memory is unreliable missing. Domains change hands. DNS records flip. Hosting moves. Tech stacks turn over. The internet rewrites itself every night, and almost no one is keeping the receipts. We are.
Four streams of evidence, captured continuously, indexed both forward and reverse. Query any domain across time, or any IP, nameserver or technology across all domains.
Every A, AAAA, NS, MX, CNAME and TXT record, scanned daily. First-seen and last-seen dates on every value. Reverse-indexed: ask which domains pointed to any IP, on any date.
Registrant, registrar, dates, contacts. The chain of custody for every domain. Diffed weekly. We keep what registrars deliberately let expire.
What's running underneath. Frameworks, CMSes, analytics, payment processors, CDN, server software, fingerprinted from response headers, HTML and JavaScript.
Every SSL certificate ever issued for a domain, sourced from Certificate Transparency logs. Subject alternative names link the public web to its private subdomains.
We don't store snapshots. We store transitions. One row per change, with the exact dates the world looked that way. Storage stays sane. History stays exact.
Beyond parsed fields, every raw response is stored compressed and addressable. When you need the exact WHOIS text from a Tuesday in 2027, it's there.
We're scanning now. The API ships when we've got enough history to be worth querying. Get a heads-up, and a founder rate that won't return, when it does.
