A diagnostic toolkit for your domain

DomainCheck exists because domain problems are invisible until something breaks: a website that stops resolving, invoices that never arrive, a phishing campaign sent in your name.

We read your domain's live DNS, interpret what we find and explain it in language you can act on — whether you are a developer, run an agency, or simply own the domain your business depends on.

Every check is deterministic. If something cannot be verified, we say so rather than marking it as passing.
