Switch from HCL to real languages
Pulumi Infrastructure as Code Engine
Stop writing HCL. Author infrastructure as code using programming languages you already know, including Python, TypeScript, Go, C#, Java, and YAML. Use the free tf2pulumi converter to migrate your existing Terraform files. Deploy to 170+ providers.
Code faster
Write infrastructure code in TypeScript, JavaScript, Python, Go, .NET, Java, and YAML using your IDE and any language ecosystem tools.
Build on any cloud
Access the full breadth of services in AWS, Azure, GCP, and 170+ providers through a complete and consistent SDK interface.
AI-powered infrastructure
Generate Pulumi code from natural language or convert existing Terraform with Pulumi AI and Neo.
Migrate from Terraform in minutes
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.
Build infrastructure faster with reusable components
Pulumi Packages
Build and reuse higher-level abstractions for cloud architectures with multi-language Pulumi Packages. Distribute the packages through repositories or package managers so your team members can reuse them.
