Pricing & limits

What each plan includes and where the hard limits are.

Every plan gets the full feature set — wildcard TLS, the API, the MCP connector and dyndns. Plans differ only in volume and support.

Other limits

  • API rate limit: 300 requests/minute per IP. Exceeding it returns 429 with a rate_limited error code.
  • TTL: 60–86400 seconds.
  • Names: 1–63 chars, lowercase letters, digits and hyphens; reserved names can't be registered.
  • Fair use: we run anti-abuse rate limiting (RRL) on the nameservers; normal workloads never hit it.
