Terraform vs Pulumi

Terraform by HashiCorp is the dominant infrastructure-as-code tool with HCL configuration language and the largest provider ecosystem. Pulumi lets engineers use TypeScript, Python, Go, or C# for infrastructure definition, appealing to developers who prefer general-purpose languages over domain-specific syntax.

Common questions

Is Pulumi better than Terraform for developers?

Many developers prefer Pulumi because infrastructure code lives in the same language as application code, enabling code sharing, better IDE support, and familiar testing frameworks.

What is OpenTofu and does it replace Terraform?

OpenTofu is an open-source Terraform fork created after HashiCorp changed Terraform's license from MPL to BSL in 2023. It is a drop-in replacement and is governed by the Linux Foundation.

Can Pulumi read existing Terraform state?

Yes, Pulumi can convert Terraform state files and HCL configurations to Pulumi programs, enabling incremental migration. The pulumi convert command handles most standard Terraform configurations.
