Infrastructure as code tools let you manage infrastructure through configuration, but they differ in how they handle state, policy, and existing resources. Compare configuration languages, drift detection, import options, and state management, as well as policy-as-code support and self-hosted execution. Supported clouds, free plans, and paid starting prices offer further points of comparison. Terraform, Pulumi, and Cloudify are among the first entries, followed by OpenTofu and Terramate. Use the ranking to weigh how each tool’s listed capabilities fit the environments and infrastructure you need to manage.
24 infrastructure as code tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
