Drift Detection now supports Terragrunt Stacks. Stacks help you manage infrastructure at scale by logically grouping OpenTofu/Terraform units into versioned entities, keeping your IaC DRY and your blast radius small (learn more). With this addition, all Gruntwork products now include native Stacks support, giving you complete flexibility to describe your infrastructure however you like—with confidence that your Gruntwork automations will work as expected.

Drift Detection auto-generates IaC represented by Terragrunt stacks before running a plan. This detects any discrepancies between resources in the cloud and those defined within your stacks.

This functionality is available now with the GitHub v4 and GitLab v2 releases. You can update by following our migration guides (GitHub guide, GitLab guide).
