Count a domain

Type a domain you own or look after. The count covers it and every subdomain in the public Certificate Transparency logs.

You have 40 counts left today (40 a day with the Shop Pass, free during preview). A domain counted in the last 6 hours opens at once and uses nothing.

What a count does

  1. Asks crt.sh (Sectigo's public log search) for every certificate logged for the domain. Busy? It tries three times, then Cert Spotter.
  2. Merges each pre-certificate with its final certificate, so each certificate counts once.
  3. Looks up the domain's CAA record and compares it with the issuers it found.
  4. Shows the stock sheet. It stays at its private address for 7 days.
