In this blog post, we’ll introduce you to OpenTofu, highlighting its features, benefits, and functionality as Terraform’s new attractive alternative.

What is OpenTofu?

OpenTofu is an Infrastructure as Code (IAC) tool designed to automate the provisioning and management of cloud resources, containers, and infrastructure components.

It’s an open-source project hosted under CNCF since September 2023, which speaks volumes about its beliefs and community support.

OpenTofu is published under the Mozilla Public License (MPL). Publishing software under MPL means that it is open source, can be freely used, modified, and distributed.

Controversy of terraform in OpenSource:

It has long been time for Terraform to be a Core component in simplifying the management of infrastructure in cloud environments. DevOps teams around the world use Terraform as the go-to tool due to its ease of use and powerful capabilities.

Recently, HashiCorp, the company behind Terraform, introduced significant license changes that have raised significant concerns within the open-source community.

Terraform Licences after 1.5 Versions are moving from Mozilla Public License v2.0 (MPLv2) to Business Source License v1.1.

which means you can have a Source code of Terraform, only if your use falls outside of the additional use, especially for commercial purposes you should have to commit a special license grant based on an individual agreement with HashiCorp.

Security patches for the MPL version will be provided until the end of December 2023.
