Best Infrastructure as Code Tools in 2025

Infrastructure as Code (IaC) has revolutionized the way organizations build, deploy, and manage their IT infrastructure. Gone are the days of manually configuring servers or wrestling with inconsistent environments. With IaC, you can define your infrastructure using code, making it version-controlled, repeatable, and scalable. As we move into 2025, the demand for robust, flexible, and efficient IaC tools has never been higher.

The rise of cloud-native technologies, multi-cloud strategies, and Kubernetes has pushed IaC tools to evolve rapidly.

Notable Mention: Proprietary IaC Tools

While open-source tools dominate the IaC space, proprietary solutions like AWS CloudFormation, Azure Resource Manager (ARM), and Google Cloud Deployment Manager offer seamless onboarding and native cloud integrations. These tools are ideal for organizations heavily invested in a specific cloud ecosystem and looking for quick setup and vendor support.

Terraform also deserves a shoutout. While it started as open-source, HashiCorp switched it to a Business Source License (BSL) in 2023, so it’s not fully open-source anymore. That said, it’s still a go-to for managing multi-cloud infrastructure, thanks to its flexible HCL language, huge provider ecosystem, and strong state management features. It’s a top pick for teams working across different cloud platforms.
