Overmind is a blast radius and change risk assessment tool for Terraform. It builds a real-time dependency graph of the cloud environment by crawling the cloud account — security groups, IAM roles, VPC networking, DNS, database schemas — and maps each node's relationships to dependent services and resources.
When a Terraform plan is submitted, Overmind traverses the dependency graph to identify which downstream services are affected by the proposed change, then generates a natural-language explanation of predicted failures before the plan is applied. PR integration triggers analysis on every pull request touching Terraform files.
Currently supports AWS; GCP and Azure on the roadmap. Free tier for small environments; paid tiers for larger estates.
