Running multiple providers with different credentials in the same Pulumi program has always been tricky. Providers expect fixed environment variable names like AWS_ACCESS_KEY_ID or ARM_CLIENT_SECRET, so if you need two AWS providers targeting different accounts, you couldn’t configure them both via environment variables.

Pulumi v3.220.0 introduces envVarMappings, a new resource option that solves this problem by letting you remap provider environment variables to custom keys.

Neo now reads AGENTS.md files, the open standard for giving AI coding tools context about your project. If you’re already using AGENTS.md, Neo will pick up those same instructions automatically.

We’re thrilled to announce that the Pulumi Cloud REST API is now described by an OpenAPI 3.0 specification, and we’re just getting started.

This is a feature that has been a long time coming. We have heard your requests for OpenAPI support loud and clear, and we’re excited to share that not only do we have a published specification for consumption, but our API code is now built from this specification as well. Moving forward, this single source of truth unlocks better tooling, tighter integration, and a more predictable API experience for everyone.

You can fetch the spec directly from the API at runtime or use it for client generation, validation, and documentation, all from one machine-readable contract.

Neo shows its work, but until now that context was only viewable by the user that initiated the conversation. When you wanted a teammate’s input on a decision Neo made, you had to describe it in Slack or screenshot fragments of the conversation. Today we’re introducing task sharing: share a read-only view of any Neo task with anyone in your organization, full context preserved.

AI coding assistants have transformed how developers write software, including infrastructure code. Tools like Claude Code, Cursor, and GitHub Copilot can generate code, explain complex systems, and automate tedious tasks. But when it comes to infrastructure, these tools often produce code that works but misses the mark on patterns that matter: proper secret handling, correct resource dependencies, idiomatic component structure, and the dozens of other details that separate working infrastructure from production-ready infrastructure.

Do you know what cloud resources are running in your environment right now? Many organizations struggle to maintain visibility across their cloud estate, especially for resources created outside of infrastructure as code. Without complete visibility, you can’t enforce compliance, optimize costs, or identify security risks.

Today, we’re excited to announce new resources in the Pulumi Service Provider that solve this problem by enabling you to discover all cloud resources and enforce governance policies programmatically using infrastructure as code.

Pulumi IaC gives us a declarative interface to updates. When we perform an update, Pulumi calculates the difference between your currently deployed infrastructure and what is being proposed, then deploys only what is required to migrate from the old state to the new state. Normally, this is exactly what we want: we minimize the amount of work required to perform the update, and don’t recreate anything unnecessarily. However, every now and then, we want to override this behavior.

We’re excited to announce that Pulumi Identity and Access Management (IAM) is now available for self-hosted instances of Pulumi Cloud. This foundational security capability brings the same enterprise-grade access management we launched for Pulumi Cloud SaaS to organizations running Pulumi on their own infrastructure.

We’re excited to announce the Stash resource, a new built-in Pulumi resource that lets you save arbitrary values directly to your stack’s state. Whether you need to capture a computed result, record who first deployed your infrastructure, or persist configuration that should remain stable across updates, Stash provides a simpler and more ergonomic solution.

The era of AI-accelerated development has arrived, creating both unprecedented opportunity and unprecedented challenge. Developers ship code faster than ever, but platform teams struggle to keep pace. The velocity gap threatens to become a bottleneck.

As 2025 comes to a close, let’s look back at how we addressed this challenge.

This year, we took a giant leap forward to close that gap with several major innovations, including purpose-built AI for platform engineers, next-generation policy management that transforms governance into an accelerator, and the foundation for building Internal Developer Platforms that enable self-service without sacrificing control.
