Pulumi Expands IaC Platform to Support Terraform, OpenTofu, and Native HCL

TL;DR

Pulumi added support for managing Terraform and OpenTofu state in Pulumi Cloud and introduced native HCL support in its infrastructure as code engine. These changes allow teams to use Terraform, OpenTofu, Pulumi languages, and HCL side by side, with shared state visibility, governance features, and AI-assisted operations available across tools.

Key Points

Highlight key points with color coding based on sentiment (positive, neutral, negative).

Pulumi has extended its platform to manage Terraform and OpenTofu state in Pulumi Cloud and to execute HCL natively in the Pulumi IaC engine. This enables Terraform- and HCL-based infrastructure to coexist with Pulumi-managed resources under a shared state, visibility, and governance layer.

Pulumi Cloud applies its AI features to Terraform and OpenTofu plans, state, and execution metadata. These features operate on dependency graphs, diffs, and historical changes to automate analysis and reduce manual review during infrastructure operations.

By supporting multiple IaC engines and languages within a single control plane, Pulumi aims to function as a tool-agnostic infrastructure management layer rather than a Terraform-only or Pulumi-only workflow.

Organizations such as Lemonade, BMW, and Snowflake have reported using Pulumi in large-scale, multi-team environments to standardize infrastructure definitions, improve component reuse, and centralize visibility across cloud accounts.

Pulumi provides technical workshops focused on IaC coexistence, migration patterns, and governance models observed in production-scale deployments.

Pulumi has expanded its support for Terraform and HCL, making it easier to run mixed infrastructure-as-code setups without forcing teams to change their existing workflows. Pulumi Cloud can now manage Terraform and OpenTofu state directly, adding centralized visibility and AI-assisted analysis on top of the usual plan and apply cycle. Teams can keep using their current CLI and language while plugging into Pulumi’s control plane. At the same time, Pulumi’s IaC engine now runs HCL natively, alongside Python, TypeScript, Go, C#, Java, and YAML. The result is a single platform that can sit on top of existing Terraform investments rather than replacing them outright.

This move comes as the infrastructure-as-code ecosystem continues to diversify, with multiple vendors proposing alternatives to traditional Terraform-centric workflows.

On the operational side, Pulumi Cloud exposes Terraform state files and workspaces with the same level of detail as Pulumi-managed stacks. Changes can be traced over time, diffs inspected, and logs reviewed, all from a single place. This setup supports gradual adoption: organizations can mix tools, migrate selectively, and still keep automation, security controls, and infrastructure visibility intact.

Pulumi also pairs these technical changes with transition-oriented programs such as usage credits during existing contract periods, modernization workshops focused on IaC practices, and cost analysis exercises. These are intended to reduce friction during adoption rather than mandate immediate migration.
