Say hello to the Pulumi Dev Center! 👋
We just launched this yesterday — a new home at pulumi.com/dev for all tutorials, templates, examples, how-to blogs, and upcoming events, all browseable and searchable and (hopefully!) easy to get around in.
I've wanted this to exist for about as long as I can remember, so I'm stoked it's finally out there. Check it out when you can! I hope it brings you some joy. 💜

Neo Security is shockingly good.
We need more defense in this world of increasing offense, and I'm happy we can play a small role on the infrastructure side of things.
Amazing what frontier models + context + tools + domain-specific skills + owning the write path, can do.
Neo Security is our infrastructure security agent.
It uses full context about your cloud estate to build a threat model, analyze it, and discover vulnerabilities. Remediations are easy thanks to IaC.
In research preview starting today: pulumi.com/blog/pulumi-neo-s…

Joe Duffy, Founder and CEO of @PulumiCorp, closed out Day 1 of CascadiaJS 2026 with a look at what happens when AI agents move beyond writing code and start handling the messy world of infrastructure, deployment, and operations.
@funcOfJoe demoed AI agents using APIs to dynamically provision infra and explored a future where the line between code and infra just completely goes away.

Had a fun time keynoting @CascadiaJS. Talk was “the last mile is code,” about how modeling problems as coding problems helps LLMs as they are natural coders.
Amazing community, thank you for having me. Demo code, video, and slides below. Ship something epic🤘

Earlier this week when we wrote about how agents are taking on more of the work of infrastructure, the share was already at 28%. Today it's even higher. Here's how it breaks down across the most popular coding agents:

What do coding agents love more than code? Well-designed CLIs. So in this week's release, we poured some love into the Pulumi CLI — and with it, brought along all of Pulumi Cloud.

Pulumi Neo is now available in the terminal.
As of today, you can run Neo from the command line with the Pulumi CLI, with all the same context it has in Pulumi Cloud, plus give it controlled access to your code and your local development environment.

We shipped some stuff today to help agents do better with infrastructure.
20% of operations on our platform are already done by agents, and it's just going to keep growing...
Being in-distribution helps. In the coming weeks, we'll share more data from our new InfraBench.
Infrastructure is entering its agentic era.
Agents are moving from writing code to operating infrastructure directly, with previews, policy checks, audit trails, and human-review built into the workflow.

These supply chain hacks are frightening.
The number of static long-lived secrets kept in CI/CD pipelines like GitHub Actions is equally terrifying.
The combination is deadly.
We developed "zero static secrets" to fix this and there's no going back.
