Pulumi

Pulumi is an infrastructure-as-code platform that lets engineering and platform teams define, deploy and manage cloud infrastructure using real general-purpose programming languages instead of a domain-specific language.

It supports TypeScript, JavaScript, Python, Go, C#, Java and YAML, so developers get familiar IDE features like type checking, code navigation and reusable components, and it works across 170+ cloud and SaaS providers.

In the AI era Pulumi introduced Neo, described as the first AI agent built for infrastructure: an agentic platform engineering assistant inside Pulumi Cloud that understands code and organizational context, respects policies, generates previews and histories, and can execute complex provisioning tasks end to end with optional human approval, including migrating existing Terraform code and state.

Beyond IaC, Pulumi offers centralized secrets and configuration management through Pulumi ESC, policy-as-code governance with natural-language querying, and internal developer platform features for self-service infrastructure. Use cases include managing multi-cloud infrastructure, building reusable infrastructure components, and automating provisioning with AI assistance and guardrails.

Pros include the power and reuse of real programming languages, broad provider coverage, and a capable AI agent with enterprise governance.

Cons are that a code-first approach has a steeper learning curve than pure declarative tools for some operators, and advanced cloud and AI features sit in paid tiers. Pulumi is freemium with a free individual tier plus paid team and enterprise plans.

Pricing changes often, so check the official site for current plans. Pulumi's core capabilities include IaC in TypeScript, Python, Go, C

and more, Neo AI agent for infrastructure tasks, Support for 170+ providers, Pulumi ESC secrets and config management, Policy-as-code governance and Terraform code and state migration.

IaC in TypeScript, Python, Go, C

and more is built in, Neo AI agent for infrastructure tasks is built in, Support for 170+ providers is built in, Pulumi ESC secrets and config management is built in, so you get a rounded toolkit rather than a single trick.

Each feature is designed to take the manual effort out of the task and help you reach a usable result faster, which is what makes Pulumi worth a place on your shortlist.

On the plus side, users consistently highlight Real programming languages enable reuse, Broad cloud and SaaS provider coverage and Capable AI agent with enterprise governance as the reasons they keep using Pulumi.

It isn't perfect, though — Code-first approach has a learning curve and Advanced features require paid plans are the trade-offs people most often mention, so weigh those against your own priorities before you commit.

As with any AI tool, the output still benefits from a quick human review, but Pulumi gets you most of the way there with far less effort.

Pulumi runs on a freemium pricing model, so you can start for free and only pay once you outgrow the free tier — handy for testing it on a real task before spending anything.

AI-tool pricing changes often, so always check the current plans, seats and add-ons on the official site for the latest details before you buy. Who is Pulumi for? It's best suited for infrastructure as code in real programming languages.

Whether you're a beginner trying this kind of AI tool for the first time or a professional who'll use it every day, it's a credible option to consider.
