OpenTofu is an open-source fork of Terraform 1.5, which was created after HashiCorp changed its license from Mozilla Public License (MPL) 2.0 to Business Source License (BSL). OpenTofu aims to provide a simple but powerful configuration language for describing infrastructure needs and offers backward compatibility with Terraform 1.5.x. It is licensed under the MPL 2.0, a true FOSS license that grants users complete freedom in using the code as they wish. The project has gained significant support from companies and individuals, including being adopted by the Linux Foundation, which provides vendor-neutral governance. OpenTofu offers several advantages over Terraform, including a more predictable future due to its open-source nature, a free and open license that allows users to use the code in their preferred manner, and a community-driven approach shaping its features. While Terraform still has its own strengths, particularly with cloud services and enterprise-level support, OpenTofu is becoming an attractive alternative for companies, digital agencies, and individual users seeking a stable and open-source IaC tool.
