Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
Terraform lets you define all of it in code files instead of clicking through AWS/GCP/Azure consoles. Write what you want, run `terraform apply`, and it creates everything.
Infrastructure as Code in any programming language
Pulumi lets you define infrastructure using real programming languages: TypeScript, Python, Go, C#, Java. Same concept as Terraform, but instead of learning a DSL, you use the language you already know with loops, conditionals, functions, and your IDE's autocomplete.
Open Terraform fork for declarative cloud infra
OpenTofu is the community fork of Terraform that stays truly open source. It's a drop-in replacement for Terraform, maintained by the Linux Foundation.
Terraform Cloud is a platform — it bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
Including when one of these alternatives ships a major update. Free.
