Today is a big day for OpenTofu! After four months of work, we're releasing the first stable release of OpenTofu, a community-driven open source fork of Terraform. OpenTofu, a Linux Foundation project, is now production-ready. It’s a drop-in replacement for Terraform, and you can easily migrate to it by following our migration guide.
In their opening paragraph they compare themselves to Terraform twice with explaining themselves once.
At least their docs do better:
Most people know of Terraform but not so much what it is. In my experience this includes a surprising number of people whose job it is to maintain templates.
