OpenTofu is a fork of Terraform made in response to a recent ambiguous license change by HashiCorp. It's open source and has been accepted by the Linux Foundation. It's backed by several organizations, including third-party vendors. The current version is compatible with the last open-source version of Terraform. Version 1.7 adds client-side encryption. The future of the OpenTofu project is unclear in terms of how closely it will support compatibility with future versions of Terraform. There are also questions around the long-term support by its current backers. We recommend keeping an eye on the project but remain cautious around usage, except for teams that have the capability to manage risks that may include being able to contribute to the codebase.
