What is Terramate used for?

Terramate is an open-source IaC orchestration platform that helps platform teams and developers manage Terraform, OpenTofu, and Terragrunt with GitOps workflows, code generation, and observability. It is a good fit for self-serve infrastructure for developers and AI agents; standardize governance, compliance, and security for platform teams; and accelerate existing Terraform, OpenTofu, and Terragrunt workflows.

Is Terramate open source?

Yes. Terramate is open source under the MPL-2.0 licence. Its source code is on GitHub at terramate-io/terramate and is written mainly in Go.

Yes. Terramate is open source, so the software itself is free to use.

Can I self-host Terramate?

Yes. Terramate can be self-hosted on your own server or infrastructure.

What is Terramate an alternative to?

Terramate is an open-source alternative to HCP Terraform, env0 and Scalr. Other open-source alternatives to HCP Terraform include Infracost, Terragrunt and Burrito.

Is Terramate actively maintained?

About Terramate

Terramate is an open-source Infrastructure as Code (IaC) orchestration platform. It provides GitOps workflows, orchestration, code generation, observability, drift detection, asset management, policies, and Slack notifications. It integrates with Terraform, OpenTofu, Terragrunt, Kubernetes, GitHub Actions, GitLab CI/CD, BitBucket Pipelines, and other CI/CD platforms.

The platform is designed for two audiences: platform teams and developers. Platform teams can productize reusable infrastructure patterns, while developers can self-serve infrastructure without requiring cloud or Terraform expertise. It includes features like Stacks, Code Generation, Orchestration, CI/CD Integration, Observability, Drift Detection, Incident Management, and Asset Inventory.

Key features

Stacks: Split Terraform, OpenTofu, and Terragrunt state files into smaller stacks that can be deployed, managed, and governed as a unit.
Code Generation: Generate infrastructure code to standardize golden paths.
Orchestration: Automate workflows across environments.
CI/CD Integration: Works with GitHub Actions, GitLab CI/CD, BitBucket Pipelines, and any other CI/CD platform.
Observability: Provides full visibility, analytics, and real-time insights across infrastructure, repositories, and teams.
Drift Detection: Detects drift and misconfiguration early.

Good fit for

Self-serve infrastructure for developers and AI agents.
Standardize governance, compliance, and security for platform teams.
Accelerate existing Terraform, OpenTofu, and Terragrunt workflows.
