Terramate CLI is an open-source Infrastructure as Code (IaC) code generation and orchestration tool for Terraform, OpenTofu and Terragrunt. With Terramate, you can:

(a) Simplify complex codebases to make your work more productive and reliable. Break down large state files with stacks to reduce run-time and blast radius and keep them DRY with native code generation.

(b) Automate and orchestrate Terraform, OpenTofu and Terragrunt in any CI/CD using Pull Request automation, GitOps blueprints, and workflow tooling with zero-config orchestration and change detection.

(c) Provide the foundation to later leverage Terramate Cloud, a management layer that gives you visibility, control, and actionable insights into your infra.

With brew:

brew install terramate

With Go:

go install github.com/terramate-io/terramate/cmd/...@latest

For other installation methods, please see the documentation.

The fastest way to get started with Terramate is our getting started guide.

As Terraform and OpenTofu offer no standard pattern on how to organize code efficiently, projects quickly sprawl out of control. The consequences are code complexity, long-running pipelines, large blast radius, drift, and poor governance.

Terramate CLI enables a new approach to eliminating the root cause of these consequences: using a modular and efficient approach called Terramate Stacks. A stack is a combination of infrastructure code, state and configuration, which can be nested to split state further.

Organizationally, a stack is a way to establish an ownership model. By consistently sizing stacks into isolated units that your team members can quickly understand, assuming ownership of your infra becomes a lot simpler. Terramate CLI supports Terraform, OpenTofu and Terragrunt, and can be run locally as well as in your existing VCS (Github, Gitlab) CI/CD.

Terramate CLI is designed to work especially well with Terramate Cloud, which provides an IaC management layer and offers a generous free tier.

• Orchestration: Run any command and configurable workflows in stacks with unlimited concurrency.
• Change Detection: Only execute stacks that contain changes. Allows to detect changes in referenced Terraform and OpenTofu modules as well as Terragrunt dependencies.
• Code Generation: Generate code such HCL, JSON and YAML to keep your stacks DRY (Don't repeat yourself). Comes with support for global variables and functions.
• Automation Blueprints: Pre-configured GitOps workflows for GitHub, GitLab, BitBucket and Atlantis to enable Pull Automation with plan previews in your existing CI/CD.
• Drift Management: Detect and reconcile drift with scheduled workflows.
• Observability, Visibility and Insights: Provides actionable insights and observability into your stacks, deployments, and resources.

Terramate Cloud provides you with the best IaC management experience possible. It helps you orchestrate your stacks in your existing CI/CD platform, such as GitHub Actions, GitLab and Bitbucket Pipelines, so you don't need to buy yet another CI/CD vendor.

It also provides a powerful dashboard that adds observability and insights, deployment metrics (e.g., DORA), notifications, drift management, asset management, and more for your stacks to provide the developer experience and infrastructure to build, scale and observe all your infrastructure managed with IaC.
