IaC has consolidated around Terraform (and its fork OpenTofu) for general cloud provisioning, with Pulumi for code-first IaC and CDK/Bicep for cloud-native options. Most teams converge on Terraform unless they have a strong reason to choose otherwise. ## Top 3 infrastructure as code tools 1.

Filter to narrow down. ## In-depth: why these tools made the cut ### Why Terraform remains the IaC standard Terraform review Terraform built the network effect: every cloud provider ships Terraform providers, every IaC tutorial uses HCL, every devops engineer knows it. After HashiCorp's BSL license change, OpenTofu is the truly open-source fork; the language and ecosystem are compatible. For new IaC projects, Terraform or OpenTofu is the default. Pulumi is the alternative when 'IaC in a real programming language' is non-negotiable. ## How to choose infrastructure as code software 1. Default to Terraform / OpenTofuTerraform's HCL is the most-used IaC language; OpenTofu is its open-source fork (after HashiCorp's BSL license change). For most teams, Terraform or OpenTofu is the rational default. 2. Consider Pulumi for code-first teamsPulumi lets you write IaC in TypeScript, Python, Go, or .NET. For engineering teams that want IaC in their primary language (rather than HCL), Pulumi is the credible alternative. 3. Use cloud-native CDK only when cloud-lockedAWS CDK, Bicep (Azure), and Pulumi-AWS work well within their respective clouds but lock you in. For multi-cloud or potential cloud migration, Terraform/OpenTofu portability matters. ## Best Infrastructure as Code for - [Infrastructure as Code for Startups](https://toolradar.com/best/infrastructure-as-code/for/startups) - [Infrastructure as Code for Small Businesses](https://toolradar.com/best/infrastructure-as-code/for/small-businesses) - [Infrastructure as Code for Freelancers](https://toolradar.com/best/infrastructure-as-code/for/freelancers) - [Infrastructure as Code for Enterprises](https://toolradar.com/best/infrastructure-as-code/for/enterprises) - [Infrastructure as Code for Students](https://toolradar.com/best/infrastructure-as-code/for/students) - [Infrastructure as Code for Solopreneurs](https://toolradar.com/best/infrastructure-as-code/for/solopreneurs) - [Infrastructure as Code for Nonprofits](https://toolradar.com/best/infrastructure-as-code/for/nonprofits) ## How we ranked these infrastructure as code tools We rank by real-world signal: G2/Capterra review volume and rating, and media mentions (volume and recency).
