OpenTofu at a glance

OpenTofu is an open-source infrastructure-as-code tool — a community-driven, Linux Foundation fork of Terraform created after its license change, and a drop-in alternative for many workflows. OpenTofu ships regular releases plus security fixes.

For admins OpenTofu behaves like Terraform: pin the CLI and provider versions for reproducible runs across the team and CI, and read the upgrade notes for state-format and provider changes before moving versions. The state file often contains secrets — keep it in a secured remote backend with locking. Compatibility with Terraform configurations is broad but diverges over time as each project adds features — check specifics when migrating or maintaining both. After upgrading, run a plan and review the diff before applying. Track your version and the project's support window; patchletter flags new OpenTofu releases.
