## What it is
CDK for Terraform (CDKTF) is a framework for defining infrastructure as code using general-purpose programming languages (TypeScript, Python, Java, C#, Go) and synthesizing it into Terraform-compatible configurations. HashiCorp announced its sunset and archived the project on December 10, 2025, so it is no longer maintained.

## Use cases
- define terraform infrastructure in typescript or python instead of hcl
- generate terraform json or hcl from programming language code
- use testing and dependency management tooling for infrastructure code
- migrate cdktf projects to standard terraform hcl
- provision cloud resources with terraform providers from code

## When to choose
- you have an existing cdktf codebase and accept unmaintained-software risk
- you want to fork the project and maintain it yourself
- you need to synthesize existing cdktf code to hcl for migration

## When to avoid
- you are starting a new infrastructure-as-code project - use standard Terraform with HCL instead
- you need long-term support, updates, or compatibility with new Terraform versions
- you want an actively maintained community or bug fixes

## Facets
- artifact type: framework
- maturity: abandoned
- function: infrastructure-as-code, deployment, developer-tools
- domain: infrastructure-as-code, cloud-computing
- platform: python, jvm, dotnet, go, cli, cross-platform
- tags: terraform, cdktf, cdk, deprecated, sunset, hcl-synthesis, multi-language-iac, devops, nodejs
