FROM PLAN TO UNDERSTANDING

Three views. One plan.

AWS infrastructure is easier to review when the changes and their relationships are visible together. Move from the map to every resource, then follow its dependencies.

Resource Map

Compact subnet previews, a grouped VPC inventory, and visible route and attachment changes. Pin a path and expand the canvas.

Plan

One entry per resource and workspace. Review destructive changes first, search addresses, and filter by resource type or action.

Graph

Inspect direct dependencies or the full graph. Follow routed arrows and open configuration without losing context.

Terradune Plan with resource-type navigation, action counts, and workspace filters — **Plan review**Every planned resource, with filters for type and action.

Resource Map after double-clicking a subnet, with its VPC, route table, gateways, and dependency lines visible — **Focused dependencies**A double-click isolates the connected resources within their VPC and subnet sections.

A TOOL FOR YOUR WORKSPACE

Local by design.

Terradune runs beside your Terraform configuration. There is no hosted Terradune account and no plan-upload service.

Terraform still contacts configured providers, backends, and data sources. Terradune never runs terraform apply.

Go: Install with Go and use the Terraform or OpenTofu CLI already on your machine.
Clear changes: Create, update, replace, destroy, and unchanged states. Unknown values stay distinct from empty ones.
Honest coverage: Generic managed-resource support, with specialized AWS layouts. Complete Terraform lifecycle parity is not claimed.

START WITH YOUR NEXT PLAN

Keep the CLI. Add the picture.

Bring an initialized workspace and the credentials Terraform already needs.
