I tried it. Terraform is config files; Pulumi is real code, and it can use every Terraform provider anyway.

## Use it when

- The client's team already runs Terraform.

## Instead, consider

- [Pulumi](https://cloudlesslabs.com/stack/pulumi/index.md): New work.

## Worked examples

- [Pulumi everywhere](https://cloudlesslabs.com/stack/guides/pulumi-everywhere/index.md): Can I provision every tool on this page from one codebase?
