Digger has rebranded to OpenTaco. You may still see legacy “digger” naming in some commands, variables, and pages while documentation is being updated.

​
What is OpenTaco?

OpenTaco helps you run Terraform and OpenTofu safely across your team. It has four major capabilities:
  • State management with access controls and version history, with an HCP Terraform-compatible interface for drop-in workflows
  • Remote runs (Beta) that execute Terraform remotely and stream logs back, similar to HCP Terraform remote execution
  • PR automation for plan/apply workflows in CI (historically Digger’s core focus)
  • Drift detection + remediation to detect infrastructure drift and close the loop through notifications and apply workflows
You can adopt all four capabilities as a full platform, or start with just the subset that fits your workflow today.
OpenTaco is open source and self-hostable. You can run it in your own environment and keep full control over your infrastructure workflows. See the self-hosting docs for setup options.

Choose your onboarding path

Start with the path that matches your immediate goal.

State Management

Store OpenTofu and Terraform state centrally with cloud blocks, tofu login, secure access controls, and rollback support. The interface is compatible with HCP Terraform for drop-in migration paths.

Remote Runs (Beta)

Run OpenTofu commands in remote execution environments similar to HCP Terraform while keeping a CLI-driven workflow (requires using OpenTaco State Management).

PR Automation

Recommended for most teams and historically Digger’s core focus. Run plans on pull requests and apply safely in CI across OpenTofu, Terraform, and Terragrunt repositories.

Drift Detection + Remediation

Detect drift on a schedule, notify via Slack or GitHub Issues, and remediate with the same command workflow your team already uses.

​
How these paths fit together

These paths are not mutually exclusive. Many teams start with PR Automation, add Drift Detection + Remediation next, and combine with State Management as they mature.

​
Common capability combinations

CombinationOutcome
All capabilitiesFull platform workflow with centralized state, CI automation, drift operations, and remote execution.
PR Automation onlySafer plan/apply collaboration in pull requests without changing your existing state backend.
State Management onlyCentralized state with access controls and version history while keeping your current CI process.
State Management + Remote Runs (Beta)Terraform Cloud-like remote execution with a CLI-first workflow.
