About Digger
Digger is an open source infrastructure as code orchestration tool written in Go and released under the MIT license. It runs Terraform natively inside an existing CI pipeline rather than on a separate hosted service, and it lives in the Terraform and OpenTofu ecosystem alongside the category of tools the project calls TACOS, or Terraform Automation and Collaboration Software. The project has been rebranded to OpenTaco as of 7 November 2025, while the company behind it remains Digger and the engine is unchanged.
