Project history

The project appeared as a public GitHub repository in March 2020, positioned around a specific gap between Atlantis pull-request automation and Terragrunt's dependency-aware HCL configuration. Its README describes Atlantis as a Terraform pull request automation tool whose YAML config can express module dependencies, then explains that Terragrunt already models those dependencies in configuration.

Rather than asking teams to hand-maintain large Atlantis config files, the tool scans for terragrunt.hcl files, evaluates dependency, terraform, locals, and related source blocks, builds a directed acyclic graph, and emits Atlantis config that reflects the graph.

Adoption history

The README frames the tool around Transcend's own monorepo use case, where Terragrunt configuration can reach thousands of lines. GitHub repository metadata showed hundreds of stars and forks by July 2026, indicating adoption beyond a private internal helper but still within the Terraform/Terragrunt/Atlantis niche.

How it is used

The recommended production pattern is to install the binary on an Atlantis server and run it from a pre-workflow hook after each clone, commonly generating atlantis.yaml with flags such as --autoplan, --parallel, and --create-workspace.

Users can tune generated Atlantis behavior with CLI flags and Terragrunt locals such as atlantis_workflow, atlantis_apply_requirements, atlantis_skip, and extra_atlantis_dependencies.

Why package nerds care

For package-manager users, the package matters because it turns a Go CLI into an installable piece of CI infrastructure: Homebrew supplies the local formula, while the README also documents go install and release tarball installation for Atlantis server images.

Timeline

• 2020: Public GitHub repository created for Transcend's Terragrunt-to-Atlantis config generator.
• 2020s: README-documented workflow centers on Atlantis pre-workflow hooks and generated atlantis.yaml files for Terragrunt monorepos.
• 2026: Homebrew metadata lists the tool as the brew formula terragrunt-atlantis-config.
