Pulumi is an infrastructure as code platform for building, deploying, and managing cloud infrastructure using general-purpose programming languages. It includes AI-assisted capabilities for generating and working with cloud infrastructure code.
Pulumi is an Infrastructure as Code (IaC) platform that lets engineering teams provision, secure, and manage cloud infrastructure using real programming languages like TypeScript, Python, Go, C#, Java, and YAML, with a generous free tier and paid plans for teams. It is built for platform engineers, DevOps practitioners, and developers who want to ship infrastructure at the speed of AI.
Founded in 2017 and trusted by over 4,000 companies including Snowflake, Mercedes-Benz, Supabase, and Lemonade, Pulumi differentiates itself from declarative tools like Terraform and CloudFormation by allowing engineers to use loops, classes, functions, package managers (npm, PyPI, NuGet), and IDE features such as type checking, code navigation, inline docs, and unit testing directly in their infrastructure code. The platform supports 170+ cloud providers and packages through its Registry, covering AWS, Azure, Google Cloud, Kubernetes, and dozens of SaaS providers, making it possible to manage truly multi-cloud, multi-region environments from a single codebase.
Beyond core IaC, Pulumi offers a complete platform for infrastructure teams: Pulumi ESC for centralized environments, secrets, and configuration (with integrations into Vault, AWS Secrets Manager, Azure Key Vault, and OIDC for short-lived credentials); Insights & Governance for natural-language asset discovery, compliance tracking, and policy enforcement across clouds; an Internal Developer Platform with golden-path templates and self-service components; and Pulumi Neo, an AI-powered infrastructure engineering agent that understands organizational context, respects policies, and can execute complex provisioning tasks end-to-end with or without human approval. The platform is SOC 2 Type II certified and offers full audit trails, encrypted secrets, and dynamic credentials by default.
Based on our analysis of 870+ AI tools, Pulumi stands out in the Infrastructure as Code category for combining genuine general-purpose-language IaC with a first-party AI agent (Neo) and a unified secrets/governance layer. Compared to alternatives like Terraform, AWS CDK, and Crossplane, Pulumi is most compelling for teams that already write production software in TypeScript, Python, Go, or .NET and want their infrastructure to live in the same toolchain rather than a domain-specific language like HCL.

Pulumi supports TypeScript, Python, Go, C#, Java, and YAML, allowing engineers to use loops, classes, inheritance, and package managers like npm, PyPI, and NuGet to build reusable infrastructure components. This unlocks IDE features like type checking, autocomplete, code navigation, inline docs, and unit testing — capabilities that DSL-based tools like Terraform's HCL cannot match. Customers report this dramatically reduces lines of code for equivalent deployments compared to declarative alternatives.
Neo is described as the first AI agent purpose-built for infrastructure engineering. It understands your existing Pulumi code, organizational context, and governance policies, then executes complex tasks like provisioning, refactoring, and debugging end-to-end. Neo can operate with a human in the loop for approvals or autonomously for routine changes, going well beyond what generic coding copilots can offer for cloud infrastructure work.
ESC provides a single interface across all of your secrets and configuration, pulling in HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, and other backends. It supports short-lived credentials via OIDC for AWS, Azure, and GCP, eliminating long-lived access keys. This centralizes secret management across teams and clouds while maintaining encrypted storage, audit logs, and RBAC.
Insights lets platform teams use natural-language queries to find managed and unmanaged resources across multiple clouds, track compliance in real time, and discover vulnerabilities before they cause incidents. Policy as code is enforceable across the entire stack, and asset management gives a unified view of cloud spend, security posture, and resource ownership. This is particularly useful for enterprises managing thousands of resources across multiple AWS accounts and clouds.
The Pulumi Registry includes 170+ cloud providers and packages covering AWS, Azure, GCP, Kubernetes, Snowflake, Datadog, Cloudflare, and many other SaaS tools. Engineers can publish reusable components to npm, PyPI, or NuGet so internal teams or the community can install them like any other software dependency. Templates are also available to deploy common architectures on any cloud with a single command.

Pulumi Neo, described as the first AI agent purpose-built for infrastructure engineering, is featured prominently as the company's flagship AI capability. Neo understands organizational context, respects governance policies, and executes complex provisioning, refactoring, and debugging tasks end-to-end with or without human-in-the-loop approval. Pulumi continues to expand its Registry beyond 170+ providers and emphasizes 'infrastructure as code for humans and agents' as its current positioning.
