SimpleACME helps administrators automate ACME DNS-01 validation for certificates without sharing their normal DNS-provider API credentials or opening a public HTTP challenge endpoint. Add a permanent CNAME per challenge owner and configure Traefik, win-acme or Certbot to update the delegated TXT record. Your own client requests, renews and installs certificates and keeps the private keys.
It is a paid service: single-domain access is USD 34.99 per year and wildcard access is USD 89.99 per year. A free account can prepare one single-domain demo, with updates blocked until paid access is active.
SimpleACME was built to simplify certificate validation when a DNS provider has no suitable API or a service should not expose an HTTP challenge endpoint. The aim is to configure a focused CNAME delegation once and reuse it with familiar ACME clients for future renewals.
