Infrastructure as Code
10 providers in this category.
Infrastructure-as-Code tools define and provision cloud resources from version-controlled code instead of manual console clicks, making environments reproducible. Some are the provisioning engines themselves; others orchestrate Terraform, OpenTofu, or Pulumi runs with policy and collaboration. Compare the language and approach, multi-cloud support, open-source versus commercial licensing, and self-hosting.
