Terragrunt

The Open Source IaC Orchestrator Platform Teams Trust

Overview

What Terragrunt does

Terragrunt is an open-source orchestration tool developed by Gruntwork that enhances Terraform and OpenTofu for managing infrastructure at scale. It enables teams to break infrastructure into independent, manageable units with separate state management, control deployment order through a Run Queue, and implement least-privilege access across environments. Terragrunt follows DRY principles by letting developers define configurations once and reuse them across organizations through includes and unified stacks. The tool automates pre and post-update tasks, handles expected cloud provider errors, and provides an infrastructure catalog with scaffolding templates so engineers can provision infrastructure without manual coding. Terragrunt is trusted by major organizations including Vodafone, Toyota, Fanatics, and OpenText.

What people use it for

Organizing Terraform code across multiple environments
Automating infrastructure deployment workflows
Implementing infrastructure as code templates for developer self-service

Softwr does not host reviews and shows no star rating for Terragrunt, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
