Community-governed, fully open-source fork of Terraform under the Linux Foundation.

Pricing
Free (open source).
OpenTofu forked from Terraform at the last version before the BSL license change, and is now governed by the Linux Foundation with contributions from HashiCorp’s original ecosystem partners. Syntax and workflow are near drop-in compatible.
Key features
- Drop-in Terraform CLI/HCL compatibility
- True OSI-approved open-source license
- Built-in state encryption
- Fast-moving community releases
Self-hosted vs. cloud
Fully self-hosted by design — there’s no vendor-managed cloud offering (yet), which is part of the point for teams choosing it specifically for license independence.

Alternatives
Terraform remains the safer default for the widest provider support. Pulumi is worth a look if HCL itself is the friction point.
