▸ Domain Intelligence Engine
A searchable database of every domain name on the internet. Free for humans, free for agents.
* as wildcard · advanced searchDomain search
↗Find registered names by keyword or wildcard across every extension we track, then carry the full result set away as CSV.
Subdomain finder
↗Pull every hostname we have seen behind a domain out of Certificate Transparency, or match a fragment across the whole hostname index.
Brand monitoring
↗Leave a keyword with us and we email you the day something matching it turns up. The first watch costs nothing.
Newly registered domains
↗See what got registered today. Zone files and certificate logs merged into one feed that never stops moving.
Bulk datasets
↗Ready-made files: a whole TLD, one issuer's estate, or a curated slice. Rebuilt on a schedule and zipped for size.
Typosquatting checkernew
↗Type a brand, get back the lookalike domains somebody has already bought, each one flagged if it is carrying a live certificate.
DNS record historynew
↗Not just what a domain resolves to now, but what it resolved to last March. Every value carries the month it appeared and the month it went away.
It's free.
Public access is free for everyone - humans, scripts, scrapers, students, pen-testers, the lot. The whole index is fed from public sources (Certificate Transparency, ICANN CZDS); the only cost is compute, and until that starts hurting we're not metering it.
- unlimited domain searches via the website
- public read-only API at /api/v1 (no key)
