The models' case: Industry-leading sub-second global record propagation, native anycast resilience, exceptional Terraform/OpenTofu/Pulumi provider maturity, and seamless CNAME flattening. The models' main caveat: Not for teams wanting pure unbundled DNS decoupled from proxy/CDN features, as proprietary proxy toggles can muddy purely declarative DNS intent and. The strongest alternative is Amazon Route 53 — The default reference for IaC DNS at scale — first-class, mature Terraform/CloudFormation/CDK/Pulumi support, deep IAM-scoped permissions, health. Not unanimous: Claude picks Amazon Route 53.
