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:
Yes true, but people that don’t know what terraform is are probably not the target audience of the beta to initial GA release announcement. The website should make clear what it does for anybody stumbling into the project, and if it doesn’t that should be improved.
The primary audience here will be people already using or about to use terraform that prefer an open source license and have been waiting for this replacement.
