OpenTofu

Open-source Terraform fork maintained by the Linux Foundation

Code & DevelopmentFree

OpenTofu is the open-source community fork of Terraform, maintained by the Linux Foundation after HashiCorp changed Terraform's license from MPL 2.0 to BUSL in 2023. It provides a fully compatible replacement for Terraform with the same CLI, providers, and state management, while remaining genuinely open-source. OpenTofu has added features beyond Terraform including provider-defined functions, state encryption, and enhanced testing capabilities, and has become the IaC tool of choice for organizations requiring OSS licensing.
