What is CDKTF?

Editorial review
CDKTF lets you define Terraform infrastructure using TypeScript, Python, Java, Go, or C# instead of HCL. Write infrastructure in languages you know, with IDE support, testing, and abstraction capabilities. Existing Terraform providers work unchanged. The CDK generates valid Terraform JSON. Constructs package reusable patterns. Teams who find HCL limiting or prefer their application languages for infrastructure code choose CDKTF for programming language benefits in Terraform workflows.

Is CDKTF worth the price?

100/100

CDKTF is entirely free, making it an incredibly generous offering compared to any paid Infrastructure as Code (IaC) solution.

It's an open-source tool that leverages existing Terraform backends without direct cost. This pricing model is best for developers and organizations looking for a code-first approach to IaC without any financial barrier.

Hidden Costs & Gotchas

How CDKTF Compares to Competitors

CDKTF, being a free open-source tool, has a significant advantage over commercial IaC platforms like Pulumi Enterprise or Terraform Cloud's paid tiers. While Pulumi offers a free tier, its advanced features and support come with a cost, unlike CDKTF which remains free for all its functionalities. Terraform Cloud's paid tiers start at $0 for the 'Standard' plan but scale up for features like concurrent runs and governance, which CDKTF doesn't directly charge for.

CDKTF FAQ

How does CDKTF enable infrastructure as code?

CDKTF allows users to define their Terraform infrastructure using familiar programming languages like TypeScript, Python, Java, Go, or C#, rather than HCL. This approach integrates infrastructure definition into standard development workflows, leveraging IDE support, testing, and abstraction capabilities.

Which teams benefit most from adopting CDKTF?

Teams that find HCL limiting or prefer to use their application development languages for infrastructure code will find CDKTF particularly useful. It is designed for developers who want to apply programming language benefits to their Terraform workflows, enhancing type safety and reusability.

How does CDKTF compare to Pulumi?

CDKTF allows users to define Terraform infrastructure using general-purpose programming languages, generating valid Terraform JSON that works with existing Terraform providers. Pulumi also uses programming languages for infrastructure, but it operates as a distinct infrastructure as code tool rather than generating Terraform configurations.

What kind of trade-offs should users consider when adopting CDKTF?

Users should be aware that CDKTF has a learning curve and can make debugging more challenging compared to direct HCL usage. While it offers programming language benefits, a foundational understanding of Terraform is still necessary, and there is some generation overhead involved.

Can CDKTF integrate with existing Terraform providers?

Yes, CDKTF is designed to work seamlessly with existing Terraform providers without requiring any changes. It generates valid Terraform JSON, ensuring compatibility with the broader Terraform ecosystem and its extensive provider network.

How is CDKTF priced?

CDKTF is free to use, meaning there is no paid plan required to utilize its features for defining infrastructure with programming languages. This makes it an accessible option for teams looking to integrate programming language benefits into their Terraform workflows.

Does CDKTF support multiple programming languages for defining infrastructure?

Yes, CDKTF supports several popular programming languages for defining infrastructure, including TypeScript, Python, Java, Go, and C#. This allows developers to choose the language they are most familiar with, leveraging existing skills for infrastructure as code.
