The Future of Terraform CDK`

2``+` 3``+

Sunset Notice`

4``+` 5``+

Terraform CDK (CDKTF) will sunset and be archived on December 10, 2025. HashiCorp, an IBM Company, will no longer maintain or develop the project after that date. Unfortunately, Terraform CDK did not find product-market fit at scale. HashiCorp, an IBM Company, has chosen to focus its investments on Terraform core and its broader ecosystem. ```6``+ ```7``+

As of December 10, 2025, Terraform CDK will be archived on GitHub, and the documentation will reflect its deprecated status. The archived code will remain available on GitHub, but it will be read-only. No further updates, fixes, or improvements (including compatibility updates) will be made. ```8``+ ```9``+

You will be able to continue to use Terraform CDK at your own risk. Terraform CDK is licensed under the Mozilla Public License (MPL). HashiCorp, an IBM Company, does not apply any additional restrictions. We encourage community forks if there’s interest in continuing development independently. ```10``+ ```11``+

Migration to HCL`

12``+` 13``+

You can use the following command to generate Terraform-compatible .tf files directly from your Terraform CDK project: ```14``+ ```15``+

`cdktf synth –hcl` ```16``+ ```17``+

This will produce readable HCL configuration files, making it easier to migrate away from Terraform CDK. After running the command, you can use standard Terraform CLI commands (`terraform init`, `terraform plan`, `terraform apply`) to continue managing your infrastructure. Please note that while this helps bootstrap your configuration, you may still need to review and adjust the generated files for clarity, organization, or best practices. ```18``+ ```19``+

Note on AWS CDK`

20``+` 21``+

If your infrastructure is defined in Terraform CDK but also tightly integrated with AWS CDK, you may find it more consistent to migrate directly to the AWS CDK ecosystem. If you are not using AWS CDK, we highly recommend migrating to standard Terraform and HCL for long-term support and ecosystem alignment. ```22``+ ```23``+
