OpenTofu

We use OpenTofu for most new projects. It proofed to be a reliable and well-maintained Open-Source alternative to Terraform.

OpenTofu is a tool for building, changing, and versioning infrastructure using the infrastructure-as-code pattern. OpenTofu supports popular service providers like AWS, Google Cloud Platform, Azure, and many more.

Infrastructure is described in configuration files, which offers and built-in functions, including conditionals and loops. OpenTofu validates configuration files before attempting to run updates, checking not only that all files use the correct syntax, but also that all parameters are accessible and the configuration as a whole is valid. In OpenTofu, you can (and should) run a plan step before applying any changes. This step precisely outlines what is going to change and why.

OpenTofu is an open-source, community-driven fork of Terraform in response to HashiCorp's license changes. It's Terraform 1.6 compatible and can act as a drop-in replacement. We watch development and ecosystem growth closely and evaluate a move from Terraform to OpenTofu in some projects.
