On August 10, 2023, HashiCorp changed its license from MPL to BUSL for their products, including Terraform. This change raises questions about the safety and long-term use of these tools under a BUSL license. Spacelift supports previous and current versions of Terraform without any change, but users may consider migrating to OpenTofu due to its advantages in continuity, stability, and progress. OpenTofu is currently 100% backward compatible with Terraform and has a growing community of support. Spacelift is one of the founding members of the OpenTofu initiative and supports its development.
