@ How is this any different from using terraform cloud?
env0 supports Terragrunt and not just Terraform. You can actually execute “terragrunt apply” remotely using env0. with Terraform cloud, you can only execute “terraform apply” remotely.
also, besides Terragrunt support, there are some other differences between env0 and Terraform cloud. I am attaching a document. You can read more here - https://www.env0.com/why-env0
