Our verdict on Terragrunt Scale
Terragrunt Scale is Gruntwork’s infrastructure automation package, combining Pipelines, Patcher, and Drift Detection. It is aimed at teams managing Terragrunt infrastructure who want drift checks within their existing CI workflows. The free tier supports up to 25 infrastructure units, while drift detection is a paid feature, making the product most relevant to teams willing to pay for drift management rather than only looking for free CI/CD tooling.
The workflow focuses on turning detected discrepancies into a reviewable change. Terragrunt plans run against infrastructure units on a schedule or manually through CI workflows. When drift is found, the system opens a pull request or merge request; after the request is merged, it applies the committed infrastructure code to bring resources back in line. Terragrunt Stacks are supported by generating their IaC before planning. This guided remediation path suits teams that want changes reviewed through their normal approval process instead of applying corrections without a request.
Fit depends on the team's infrastructure and CI environment. The software runs within GitHub Actions or GitLab CI runners and lists OpenTofu and Terraform alongside Terragrunt integrations, but the drift workflow itself is centered on Terragrunt. Published plans include a Free tier, Team, and Enterprise: the free tier is described as a way to try Pipelines, drift detection is an upgrade for Team and listed among Pipelines features for Enterprise. According to the vendor's pricing page, Team and Enterprise are Contact Us plans; Team contracts are monthly or annual, while Enterprise contracts are annual. Terragrunt teams already using either CI platform should consider it; teams seeking a general-purpose drift tool or a free drift-detection plan should look elsewhere.
