# OpenTofu Project

> env zero is a founding member of OpenTofu, the open-source Terraform-compatible IaC tool backed by the Linux Foundation with a large provider ecosystem.

# OpenTofu

env zero is proud to be a founding member and active contributor to [OpenTofu](https://opentofu.org/), the open-source Infrastructure-as-Code (IaC) tool that serves as a drop-in replacement for Terraform.

## Our involvement

As one of the founding companies behind OpenTofu, env zero helped establish this community-driven initiative in response to HashiCorp's license change from open-source to the Business Source License (BUSL). We believe that Infrastructure-as-Code tools should remain open-source and accessible to the entire community.

env zero continues to actively contribute to OpenTofu's development and supports its mission to provide a reliable, flexible, and community-driven alternative to Terraform.

## Key benefits

OpenTofu offers several advantages for Infrastructure-as-Code management:

* **Drop-in replacement**: Seamlessly works with existing Terraform configurations
* **Open-source**: Maintains the open-source principles that made Terraform successful
* **Community-driven**: Developed by a diverse community of contributors
* **Feature parity**: Maintains compatibility with Terraform while adding new capabilities
* **Extensive ecosystem**: Access to 3,900+ providers and 23,600+ modules
