OpenTofu, an open-source project serving as a fork of legacy MPL-licensed Terraform, has released its first stable version. It was developed in response to HashiCorp's change in Terraform's licensing from Mozilla Public License (MPL) to Business Source License (BSL), which imposed limitations on the use of Terraform for commercial purposes. OpenTofu ensures that one of the core and most popular IaC tools remains open-source, offering a reliable, community-driven solution under the Linux Foundation. It supports infrastructure as code (IaC) and is backward compatible with Terraform's infrastructure up to version 1.6.
