What is Terraform Plan Explorer?
The Terraform Plan Explorer parses the JSON output of terraform show -json plan.out entirely in your browser. It summarizes how many resources will be created, updated, deleted or replaced, filters resources by action or address, and shows before and after values for every changed attribute so plan review takes seconds instead of squinting at raw JSON.
Key Benefits
- Counts for create, update, delete and replace at a glance
- Attribute-level diffs with unchanged keys hidden
- Action filter and address search for fast triage
- Sensitive plans stay on your machine, never uploaded
- Free and instant - everything runs in the browser
Common Use Cases
- •Reviewing infrastructure changes before terraform apply
