What is Terramate CLI?
Terramate CLI is an open-source Infrastructure as Code (IaC) orchestration tool for Terraform, OpenTofu, Terragrunt, Pulumi, Cloud Formation, CDK, Azure Resource Manager (ARM), Kubernetes, and others, that unifies, simplifies and scales all your infrastructure code, tools, and workflows.
The main value proposition of Terramate CLI is to simplify the management and improve the scalability of your Infrastructure as Code projects by using a modular and efficient approach called Terramate Stacks.
Quick Install
With brew:
brew install terramate
With Go:
go install github.com/terramate-io/terramate/cmd/...@latest
Getting Started
The fastest way to get started with Terramate is our getting started guide.
What are Terramate Stacks?
Terramate Stacks are modular, standardized, and tooling-agnostic units that represent a set of infrastructure resources. They are often used to group, organize and manage various isolated components of an application or infrastructure and support technologies such as Terraform, OpenTofu, Terragrunt, CDK, Pulumi, Cloud Formation, Azure Resource Manager (ARM), Kubernetes (Helm, kubectl, Kustomize), and others.
You can think about a stack as a combination of source code, the current state of the managed infrastructure (e.g., Terraform state file), and configuration.
There are several benefits to using Terramate Stacks:
✅ Limit the blast radius and risk of infrastructure changes
✅ Significantly faster run times and lower costs
✅ Better ownership management and governance
✅ Improved productivity and developer experience while reducing complexity
✅ Better observability and security
✅ Enables multi-step and multi-IaC use cases
Terramate Stacks can be cloned, nested, compared and orchestrated. You can also generate code in stacks to keep them DRY (e.g., generate files such as the Terraform backend configuration for all stacks that manage Terraform resources).
Terramate Stacks are created using a single command.
terramate create path/to/new/stack
What is an IaC orchestrator?
An orchestrator allows you to execute commands in stacks while defining the order of execution, dependencies, and more. Terramate CLI comes with a powerful orchestration and execution engine that allows you to easily invoke commands in stacks.
terramate run <CMD>
Terramate CLI also comes with a change detection, that seamlessly integrates with git enabling you to execute commands in stacks that contain changes only.
E.g., invoke terraform apply in all stacks that contain changes:
terramate run --changed -- terraform plan
Another example is to invoke a command in all stacks that have the tags k8sandprd, and that contain changes.
terramate run --changed --tags k8s:prd -- kubectl apply
Terramate CLI is designed and implemented by long-time DevOps, Cloud and Platform Engineering practitioners based on previous experience working with large-scale platforms in some of the most sophisticated companies in the world. It focuses on significantly improving the developer experience and productivity and integrates with existing tooling in a non-intrusive way without major lock-ins and for a broader audience.

What are the most common use cases of Terramate CLI?
📈 Implement and maintain highly scalable IaC projects
Stacks unlock faster execution, better collaboration, and lower blast radius risk. With stacks, parallel deployment ensures no more pipeline run bottlenecks.
🔗 GitOps workflows that run in your existing CI/CD platform
Unlock CI/CD workflows to orchestrate your stacks in your existing CI/CD platform, such as GitHub Actions, GitLab and Bitbucket Pipelines. Can be used to preview changes and plans in Pull Requests or to detect infrastructure drift with scheduled runs.
🏎 Deploy significantly faster and more often
Change detection allows you to execute only commands in stacks that have been changed in the current branch or since the last merge, reducing CI/CD runtimes to a bare minimum, even in complex environments, saving costs and improving throughput.
👷 Better developer productivity and experience
Simplified management and improved productivity by providing developer-centric workflows like one-click cloning stacks and environments. Enable developers to use templates to deploy complex infrastructure without requiring them to learn the complexity of IaC.
⚒️ Data Sharing
Share data across stacks with globals that can be inherited, merged, or overwritten in your stack hierarchy. Use input and output data from one stack and IaC technology as input data in another.
💫 Code Generation
Keep your code DRY by automatically generating and updating repetitive code, such as the Terraform provider and backend configuration. Always generates native code that integrates seamlessly with third-party tooling.
Terramate Cloud
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.
