Terraform Plan Visualisation & Governance

About Stratum

Stratum turns raw Terraform plan output into a visual, colour‑coded diff that highlights every change—including attribute‑level details and destructive actions—while providing OPA policy enforcement, approval gates, CI integration, immutable audit trails, break‑glass procedures, cost estimation via Infracost, and version management. The service is offered as an early‑access product launching in autumn 2026.

Capabilities

Visual Terraform plan diff

Approval gates & CI integration

Supports peer‑review approvals and can be incorporated into CI pipelines to enforce governance before apply.

Immutable audit trail & break‑glass procedures

Records a tamper‑proof history of plan reviews and provides emergency override mechanisms.

Cost estimation (Infracost)

Shows projected monthly cost impact inline with each plan diff, restoring cost visibility without HCP Terraform fees.
