All your domains. One interface.
happyDomain brings every DNS zone you manage across registrars, providers and self-hosted name servers into one calm space, clearly organized by service.
Online version closed, beta access only
happyDomain is evolving: soon, continuously test your domains' security and monitor every service exposed through DNS, with zero configuration. We're rolling out this new version progressively to gather feedback and deliver the best possible service. Learn more.
Deep checks on everything your domain exposes
The moment a domain joins happyDomain, our checkers start inspecting it from the outside, exactly as the rest of the world sees it. From the registration down to each live service, every layer is covered.
Your registration
Expiration date, transfer lock, registrar status: the administrative side of your domain, watched continuously.
Your DNS zone
DNSSEC validity, delegation consistency, server response: the technical foundation, verified end to end.
Your live services
Websites, certificates, mail: every service your domain points to, probed like a real visitor would.
Remember that subdomain you stopped using?
Someone on the team once spun up a landing page at a hosting provider, pointed a CNAME at it, then cancelled the subscription and moved on. The record stayed. It is still there tonight, patiently pointing at an address nobody owns any more. Anyone can claim that address and inherit your name with it: publish whatever they like, receive the mail meant for you, even get a perfectly valid certificate. Your visitors will have no reason to be suspicious. The padlock will be green.
Surely someone would notice, right? The reference study on the topic, presented at ACM CCS 2016, went looking and found 467 exploitable dangling records across 277 of the Alexa top 10,000 domains and 52 .edu zones. Nobody had noticed those either. Since then, top universities have been caught serving porn through forgotten CNAMEs in April 2026, and a typo in one of MasterCard's name servers went unnoticed for nearly five years, until January 2025. All of them had security teams. The record that gets you is never the one you remember creating, so happyDomain remembers for you: the dangling-records checker walks every pointer in your zone, resolves each target and verifies who actually owns it. You hear about the forgotten record first, not last.
