Digger review
An open-source drift workflow for teams running Terraform or OpenTofu through GitHub Actions.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Digger, now rebranded as OpenTaco, is an open-source infrastructure workflow platform for teams managing Terraform, OpenTofu, or Terragrunt. Its drift feature compares live infrastructure with infrastructure-as-code definitions on a schedule, then reports status in the app and can send alerts to Slack. Teams looking for an open-source way to add drift checks to GitHub Actions workflows are the clearest fit; it also offers cloud and self-hosted deployment options.
Drift detection is scheduled, with intervals including hourly, daily, or a custom crontab. This is useful for teams that want recurring checks without treating the feature as continuous monitoring or an on-demand scan. When drift appears, Digger supports remediation through the team's existing pull-request workflow. Its broader workflows automate Terraform and OpenTofu plan and apply steps, while centralized state management adds access controls and version history. These capabilities make it more than a drift-status dashboard, but the workflow remains oriented around IaC changes and PR review.
The listed integrations are GitHub Actions and Slack, so teams that depend on a wider set of CI or notification integrations may need a different fit. The product is open source, has a free plan, and can be self-hosted; support is through the community. Choose Digger/OpenTaco if scheduled drift checks, Slack alerts, and PR-based Terraform or OpenTofu remediation fit your process. Look elsewhere if you require continuous detection, broader listed integrations, or dedicated support.
