Alternatives to Terraform
Infrastructure as code tool for provisioning and managing cloud and on-prem resources
Terraform ranks #4 of 8 in Infrastructure as Code, with an Alt Score of 81. It is licensed under Business Source License 1.1 (BUSL-1.1), open source with paid hosting from $0.10/resource/mo and available on Windows, macOS, Linux and Web. 12 of 12 checklist rows are verified against a public source.
Terraform is HashiCorp's infrastructure as code tool for defining, provisioning, and versioning cloud and on-premises resources through a declarative configuration language (HCL) and a plan/apply workflow. It works through hundreds of community- and vendor-maintained providers listed on the Terraform Registry, and pairs with an optional hosted service, HCP Terraform (formerly Terraform Cloud), for shared state, remote runs, and policy enforcement. HashiCorp, Terraform's publisher, was acquired by IBM in a deal that closed February 27, 2025, and Terraform itself has been licensed under the Business Source License (BUSL-1.1) rather than its original MPL-2.0 since version 1.6 in August 2023.
Platform, DevOps, and infrastructure teams who provision and manage cloud and on-premises resources through version-controlled configuration rather than manual console changes.
A CLI and configuration language for declaring infrastructure resources across hundreds of providers, a state file that maps configuration to real-world objects, a public/private module and provider registry, and an optional hosted control plane (HCP Terraform) for remote state, runs, and team collaboration.
Users write declarative configuration files, run terraform plan to generate an execution plan previewing what will change, and run terraform apply to carry out the proposed create/update/destroy actions against provider APIs in dependency order.
