Infrastructure work ranges from simple updates to complex multi-stack operations. For straightforward tasks, jumping straight to execution is often fine. But complex tasks benefit from deliberate upfront thinking: understanding what exists, identifying dependencies, and agreeing on an approach before anything changes. Today we’re launching Plan Mode, a dedicated experience for collaborating with Neo on a detailed plan before execution begins.
Supply chain attacks on CI/CD pipelines are accelerating. A growing pattern involves attackers compromising popular GitHub Actions through tag poisoning — rewriting trusted version tags to point to malicious code that harvests environment variables, cloud credentials, and API tokens from runner environments. The stolen credentials are then exfiltrated to attacker-controlled infrastructure, often before anyone notices.
For every engineering organization, the question is no longer if your CI pipeline will encounter a compromised dependency, but what is exposed when it does.
At Pulumi, we asked ourselves that question and decided the answer should be “nothing useful.” Here’s how we got there.
Since the launch of Pulumi IAM with custom roles and scoped access tokens, organizations have been using fine-grained permissions to secure their automation and CI/CD pipelines. As teams scale to hundreds or thousands of stacks, environments, and accounts, the next challenge is applying those permissions efficiently.
Today, we’re introducing three new capabilities to help you manage permissions more dynamically at scale: tag-based access control, team role assignments, and user role assignments.
Pulumi’s OPA (Open Policy Agent) support is now stable. The v1.1.0 release of pulumi-policy-opa makes OPA/Rego a first-class policy language for Pulumi with full feature parity alongside the native TypeScript and Python policy SDKs. Write Rego policies that validate any resource Pulumi manages, across AWS, Azure, GCP, Kubernetes, and the rest of the provider ecosystem. If you already have Kubernetes Gatekeeper constraint templates, a new compatibility mode lets you drop those .rego files directly into a Pulumi policy pack and enforce them against your Kubernetes resources without modification.
Pulumi ESC (Environments, Secrets, and Configuration) allows you to compose environments by importing configuration and secrets from other environments, but this also means a child environment can silently override a value set by a parent. When that value is a security policy or a compliance setting, an accidental override can cause real problems. With the new fn::final built-in function, you can mark values as final, preventing child environments from overriding them. If a child environment tries to override a final value, ESC raises a warning and preserves the original value.
The Pulumi Registry now supports browsing documentation for previous versions of first-party Pulumi providers. If you’ve ever needed to look up the API docs for an older provider version, you no longer have to dig through Git history or guess at changes — the docs are right there in the Registry. These docs also help Pulumi Neo and other agents more accurately assist you with your Pulumi code and operations.
Many developers and platform engineers already use Google accounts daily for email, cloud console access, and collaboration. Until now, signing in to Pulumi Cloud required a GitHub, GitLab, or Atlassian account, or an email/password combination. Today, we’re adding Google as a first-class identity provider, so you can sign in to Pulumi Cloud with the same Google account you already use for everything else.
Your version control provider shouldn’t limit your infrastructure workflows. Pulumi Cloud now works with GitHub, GitHub Enterprise Server, Azure DevOps, and GitLab. Every team gets the same deployment pipelines, PR previews, and AI-powered change summaries regardless of where their code lives.
Pulumi has a lot of engineers. It has marketers, solution architects, developer advocates. Everyone has something to contribute to docs and blog posts — domain expertise, hard-won lessons, real-world examples. What they don’t all have is familiarity with our Hugo setup, our style guide, our metadata conventions, or where a new document is supposed to live in the navigation tree. I joined Pulumi in July 2025 as a Senior Technical Content Engineer. A few weeks in, my sole teammate departed. The docs practice was now, functionally, me.
The problem was clear enough: how do you take one docs engineer’s accumulated knowledge and make it available to everyone who needs it, without that engineer becoming a bottleneck?
I started packaging it. Here’s what that looked like in practice.
In January, we introduced a major performance enhancement for Pulumi Cloud through a fundamental change to how Pulumi manages state that speeds up operations by up to 20x. After a staged rollout across many organizations, it is now enabled by default for every Pulumi Cloud operation. No opt-in required—just use Pulumi CLI v3.225.0+ with Pulumi Cloud. The improvement applies to pulumi up, pulumi destroy, and pulumi refresh; pulumi preview does not modify state, so it is unchanged.
