The Linux Foundation

The Linux Foundation’s OpenTofu project carries forward the spirit of infrastructure-as-code that once drove HashiCorp’s Terraform community, offering a truly open-source alternative for provisioning and managing multi-cloud environments. Written in Go and released under the Mozilla Public License, OpenTofu interprets the same HashiCorp Configuration Language (HCL) plans, state files, and provider ecosystem, so existing Terraform modules can be adopted with minimal friction while remaining free from proprietary licensing changes. Typical use cases span the full modern DevOps lifecycle: development teams spin up parallel Kubernetes clusters on AWS, Azure, or Google Cloud for feature-branch testing; site-reliability engineers enforce policy-as-code with Sentinel-style checks to keep security groups and storage buckets compliant; and platform architects version entire landing zones in Git, enabling reproducible staging and production environments that can be recreated in minutes after disaster-recovery events. Because the binary exposes the familiar CLI workflow—init, plan, apply, destroy—CI/CD pipelines written for Jenkins, GitLab CI, or GitHub Actions require only a one-line substitution to switch tooling. Modules published to the public registry cover everything from low-level networking primitives to high-level application blueprints for PostgreSQL, Kafka, or Helm-based micro-stacks, while enterprise teams can self-host private registries and remote state backends encrypted at rest. OpenTofu software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest upstream release and supporting batch installation alongside other infrastructure utilities.
