Terragrunt is a command-line tool that simplifies managing multiple Terraform or OpenTofu configurations across different environments and AWS accounts. It reduces code duplication by letting you define infrastructure once and reuse it across projects, while handling configuration management, remote state setup, and dependency orchestration automatically. Developers use it to scale Infrastructure as Code projects without maintaining repetitive boilerplate code in each deployment.
