OpenTofu

Launched in late 2023 following HashiCorp's controversial transition from an open-source license to a restrictive Business Source License (BSL), OpenTofu was formed as an urgent industry coalition to keep infrastructure-as-code democratic. Supported by major tech organizations, including the CNCF and Linux Foundation, OpenTofu ensures that full backward-compatibility with existing Terraform configurations is preserved while continuing to introduce native architectural improvements. The framework acts as a highly reliable compiler tool that translates descriptive configuration code maps directly into structural actions across major clouds like AWS, Azure, and Google Cloud, providing developers an uncompromised, truly open-source runtime engine to manage cloud configurations at an immense scale safely.
