acme-dns – simplified DNS server

acme-dns is a simplified DNS server with a RESTful HTTP API to provide a simple way to automate ACME DNS challenges.

It provides a simple API exclusively for TXT record updates and should be used with ACME magic “_acme-challenge” – subdomain CNAME records.

This is free and open source software.

Key Features

  • Simplified DNS server, serving your ACME DNS challenges (TXT).
  • Custom records (have your required A, AAAA, NS, etc. records served).
  • HTTP API automatically acquires and uses Let’s Encrypt TLS certificate.
  • Limit /update API endpoint access to specific CIDR mask(s), defined in the /register request.
  • Supports SQLite & PostgreSQL as database backends.
  • Rolling update of two TXT records to be able to answer to challenges for certificates that have both names: yourdomain.tld and *.yourdomain.tld, as both of the challenges point to the same subdomain.
  • Simple deployment.
