OpenTofu is a software project for infrastructure as code that is managed by the Linux Foundation.
In August 2023, after HashiCorp had relicensed Terraform from MPL to BUSL, a fork of Terraform, OpenTF, was created that continued under the MPL. In September, the project was renamed to OpenTofu due to trademark concerns.
In April 2024, HashiCorp sent a cease and desist notice to the OpenTofu project, stating that it had incorporated code from a BUSL-licensed version of Terraform without permission and "incorrectly re-labeled HashiCorp's code to make it appear as if it was made available by HashiCorp originally under a different license." OpenTofu denied the allegation, stating that the code cited had originated from an MPL-licensed version of Terraform.
