# terramate-io/terramate

Open-source Infrastructure as Code (IaC) orchestration platform: GitOps workflows, orchestration, code generation, observability, drift detection, asset management, policies, Slack notifications, and more. Integrates with Terraform, OpenTofu, Terragrunt, Kubernetes, GitHub Actions, GitLab CI/CD, BitBucket Pipelines, and any other CI/CD platform.

## What it is
Terramate is an open-source Infrastructure as Code orchestration and code generation platform written in Go, designed to help Terraform, OpenTofu, Terragrunt, and Kubernetes projects scale. It provides stack management, dependency-aware orchestration with change detection, GitOps automation in any CI/CD, and optional cloud features for observability, drift detection, and asset management.

## Use cases
- orchestrate terraform apply across multiple stacks with change detection
- split large terraform state files into smaller stacks
- generate terraform backend and provider configurations to keep code DRY
- automate infrastructure deployments with gitops in github actions or gitlab ci
- detect and manage configuration drift in terraform infrastructure
- add pull request previews for infrastructure changes
- manage multi-environment terraform deployments

## When to choose
- you manage large or monolithic Terraform/OpenTofu codebases that need to scale
- you want dependency-aware orchestration and change detection for IaC runs
- you want to automate infrastructure delivery via GitOps in your existing CI/CD
- you need drift detection, observability, or asset inventory for IaC
- you want to reduce code duplication with programmatic code generation

## When to avoid
- you only have a single small Terraform project with simple needs
- you use Pulumi or Ansible as your primary IaC tool (support is not yet available)
- you need a fully self-hosted TACOS alternative without any cloud component for advanced features
- you want a GUI-first infrastructure management tool rather than a CLI workflow
