# Alternatives to OpenTofu OpenTofu is an open-source infrastructure-as-code tool stewarded by the Linux Foundation, created as a fork of Terraform after HashiCorp relicensed Terraform under the BUSL. It is licensed under the Mozilla Public License 2.0, uses the same HCL-based configuration language as Terraform, and works as a drop-in replacement with a large ecosystem of providers and modules. Unlike upstream Terraform's OSS releases, OpenTofu also ships built-in state and plan encryption at rest. OpenTofu ranks #5 of 8 in Infrastructure as Code, with an Alt Score of 74. It is licensed under Mozilla Public License, version 2.0, free from Free and available on Windows, macOS and Linux. 12 of 12 checklist rows are verified against a public source.
