Using OpenTofu with Hashicorp Terraform Cloud

OpenTofu is the open-source fork of Terraform.

It advertises itself as a drop-in replacement for Hashicorp Terraform.

If you’re wondering whether you can use Hashicorp’s Terraform Cloud backend with OpenTofu, you can.

All you need to do is set the hostname explicitly in your cloud backend definition to app.terraform.io.

terraform {
  cloud {
    organization = "example_corp"
    ## Required for Terraform Enterprise; Defaults to app.terraform.io for Terraform Cloud
    hostname = "app.terraform.io"
  }
}
