Terratag is a CLI tool that automatically applies tags or labels across an entire set of Terraform/OpenTofu (and Terragrunt) files, targeting AWS, Azure, and GCP resources. It rewrites HCL files so tags stay consistent across infrastructure codebases.
Use cases
- automatically tag all terraform resources across a codebase
- retroactively add tags to existing terraform iac files
- enforce consistent tagging for cloud cost management
- apply labels to GCP resources in terraform
- add tags to AWS and Azure terraform modules at scale
When to choose
- you manage large Terraform/OpenTofu codebases on AWS, Azure, or GCP and need consistent tags
- you want to retroactively tag existing infrastructure code without manual edits
- tagging is required for cost allocation, reporting, or governance
When to avoid
- you don't use Terraform/OpenTofu or Terragrunt for infrastructure
- your cloud provider or resources are outside AWS, Azure, and GCP
- you need runtime tagging enforcement rather than code rewriting
