Pro and API (coming soon)

Last updated 2026-10-13

Every tool on Domain Check Desk is free and stays free. We are considering a paid option for people who look after many domains — agencies, IT teams and email senders. It does not exist yet. If it sounds useful, leave your email below and we will write to you once, when it opens.

What stays free

  • Every lookup, checker, decoder and generator on the site, one domain at a time, with the full result.
  • Sharing a result through its page address.

What Pro or the API would add

  • Monitoring: scheduled checks of DNS records, SPF/DMARC, certificate expiry and security headers, with an email when something changes or is about to expire.
  • Bulk checks: a list of domains checked in one go, with one report.
  • An API for the same lookups, for your own dashboards and scripts.

We will only build these if enough people ask for them, and we will not take payment until they work.
