How do I generate a Terraform JSON plan file?

Run 'terraform plan -out=tfplan' followed by 'terraform show -json tfplan > plan.json'. You can then upload or paste the resulting plan.json into this tool.

Is my cloud infrastructure configuration uploaded to any remote server?

No. The entire plan parser runs locally in your browser sandbox using client-side JavaScript. Your cloud resource names, IPs, and architecture never leave your machine.

Understanding Terraform Plan Blast Radius

Before applying infrastructure changes with terraform apply, inspecting the exact changes protects against inadvertent database destructions, network disruption, or security group misconfigurations.

Action Types Explained

Create (+): A new cloud resource will be provisioned.
Update In-Place (~): Existing resource attributes will be modified without downtime.
Destroy (-): The cloud resource will be permanently deleted.
Replace (-/+): Changing an immutable attribute forces Terraform to delete the existing resource and create a new one, which can cause severe data loss or downtime.
