Free Migration Tools

Use tf2pulumi to convert your existing Terraform HCL to Python, TypeScript, Go, or C#. Import existing state with pulumi import. Keep your current infrastructure running while you migrate at your own pace. No forced deadlines. No resource caps.

Convert HCL to real code

The tf2pulumi tool converts your .tf files to Pulumi programs in your language of choice. Try it at pulumi.com/tf2pulumi.

Import existing state

Already have infrastructure managed by Terraform? Import your state directly into Pulumi without re-provisioning. Zero downtime migration.

No 500 resource limit

Pulumi Cloud’s free tier has no managed resource caps. Manage as many resources as you need. Scale when you’re ready.
