LAUNCHING AUTUMN 2026
# aws_db_instance.postgres will be destroyed
The plan diff you can
actually read.
Stratum turns Terraform plan output into a visual diff that makes every change impossible to miss — colour-coded by action, attribute-level detail, and destructive operations front and centre.
✓ You're on the list — we'll let you know when Stratum launches.
Early access in autumn 2026. No spam, ever.

Cost estimation — available from day one
Stratum integrates with Infracost to show monthly cost impact inline with every plan diff. HCP Terraform removed cost estimation in March 2026 — Stratum brings it back, free, without a platform subscription.
