www.linuxfoundation.org
Backed by industry leaders and hundreds of developers, OpenTofu is set to become the go-to infrastructure as code solution.

It looks like the ‘TF’ part of OpenTF was too similar to Terraform and they have come up with a new name for the project. In addition, the project is now a part of the Linux Foundation and they have a new website.
