Best Infrastructure as Code Tools in 2026
Managing infrastructure through configuration involves choices about languages, clouds, and how changes are tracked. Compare state management and drift detection with importing existing resources, policy-as-code support, and self-hosted execution. The supported clouds, free-plan availability, and paid-from pricing offer additional dimensions for assessing fit. Terraform, AWS CloudFormation, and Cloudify are among the tools shown, along with Kusion and Pulumi. Use these listed criteria to consider how each option aligns with the infrastructure you manage and the workflows you need to support.
