The explicit behavior of IAC version managers is quite crucial. It is especially critical in the realm of Terraform and OpenTofu because tool upgrades might destroy or corrupt all managed infrastructure. To protect users from unexpected updates, all version managers have to work clearly and without any internal wizardry that cannot be explained without a deep dive into the sources.
Tenv is a versatile version manager for OpenTofu, Terraform, Terragrunt, and Atmos, written in Go and developed by tofuutils team. This tool simplifies the complexity of handling different versions of these powerful tools, ensuring developers and DevOps professionals can focus on what matters most — building and deploying efficiently.
