OpenTofu
OpenTofu is a Terraform fork, created as an initiative of Gruntwork, Spacelift, Harness, Env0, Scalr, and others, in response to HashiCorp’s switch from an open source license to the BUSL. The initiative has many supporters. On the technical level, OpenTofu 1.6.x is very similar feature-wise to Terraform 1.6.x. In the future, the projects feature sets will diverge. The other main difference is that OpenTofu is open source, and it's goal is to be driven collaboratively with no single company being able to dictate the roadmap. Companies will encounter more difficulties with the situation. Switching to a new project carries risks, but staying with a project that changes its license without warning is far riskier. This risk is minimized by giving OpenTofu to the Linux Foundation, and OpenTofu’s aim of maintaining feature parity with Terraform for future releases reduces the technical risks.

Terraform
Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files. Write infrastructure as code using declarative configuration files. HashiCorp Configuration Language (HCL) allows for concise descriptions of resources using blocks, arguments, and expressions. Run terraform plan to check whether the execution plan for a configuration matches your expectations before provisioning or changing infrastructure. Apply changes to hundreds of cloud providers with terraform apply to reach the desired state of the configuration. Define infrastructure as code to manage the full lifecycle — create new resources, manage existing ones, and destroy those no longer needed.

Datree
Block misconfigurations, not deployments. Automated policy enforcement for Infrastructure as Code. Enforce policies to prevent misconfigurations in Infrastructure as Code such as Kubernetes, Terraform, CloudFormation, and more. Achieve application stability with automatic tests of every code change for policy violations or misconfigurations that may cause service outages or degraded performance. Adopt cloud-native infrastructure with minimal risk by applying built-in policies, or create custom policies to meet specific requirements. Focus on building better applications, not on infrastructure, by enforcing built-in policies for Kubernetes, Terraform, CloudFormation, and other infrastructure orchestrators. Eliminate manual code reviews for infrastructure-as-code changes, with checks that run automatically on every pull request. Keep the current DevOps workflow, with policy enforcement that integrates seamlessly with existing source control systems and CI/CD pipelines.

Massdriver
At Massdriver, we believe in prevention, not permission, letting ops teams enforce guardrails while developers deploy confidently. Our platform encodes your non-negotiables into self-service modules built with your preferred IaC (Terraform, Helm, OpenTofu, etc.) standardizing infrastructure across AWS, Azure, GCP, and Kubernetes out-of-the-box.
By bundling policy, security, and cost controls into functional IaC assets, Massdriver cuts overhead for ops teams and speeds developer workflows. Through a central service catalog, developers can provision what they need with integrated monitoring, secrets management, and RBAC baked in. No more brittle IaC pipelines; ephemeral CI/CD spins up automatically from each module’s tooling.
Scale faster with unlimited cloud accounts and projects, all while reducing risk and ensuring compliance. Massdriver—fast by default, safe by design.
