   To rank higher add native managed state, policy, drift, RBAC, and reporting as a cohesive platform

6. 6
   TTerramatenew1 pts

   GPT —Claude #5Gemini —Grok —

   Open-source-first approach that layers orchestration, stacks, and change detection on top of plain Terraform/OpenTofu in your own git repo and CI, with Terramate Cloud adding drift detection and observability without taking over state.

   To rank higher Ship a more complete managed state and RBAC story — teams still need to bring their own backend, which keeps it a companion tool rather than a full platform.
