Pulumi

Infrastructure as Code using real programming languages — TypeScript, Python, Go, C#, Java.

Pulumi is a modern Infrastructure as Code platform that lets teams define cloud infrastructure using familiar programming languages instead of DSLs. Supports TypeScript, Python, Go, C#, Java, and YAML across major clouds, Kubernetes, and a broad Pulumi Registry with Terraform-derived provider coverage. Offers testing, IDE autocomplete, reusable components, and Pulumi Cloud state/governance features.

About Pulumi

Pulumi takes a fundamentally different approach to Infrastructure as Code by letting developers use general-purpose programming languages they already know. Instead of learning HCL (Terraform) or YAML, teams can use TypeScript, Python, Go, C#, or Java with full IDE support, type checking, testing, and all the software engineering practices they're accustomed to.

The platform supports major clouds, Kubernetes, and a broad Pulumi Registry that includes native packages plus Terraform-derived providers. Pulumi AI can generate infrastructure code from natural language prompts, while Pulumi Cloud adds state management, secrets and configuration, environments, collaboration controls, RBAC, drift detection, governance, and policy-as-code.

Pulumi is open source (Apache 2.0) for the CLI and SDKs. Pulumi Cloud offers a free individual tier; current public Team pricing starts at $40/month with included resources, and Enterprise options are handled separately.

Crossplane

Kubernetes-native cloud infrastructure control plane

Crossplane is a CNCF Graduated open-source project that extends Kubernetes to manage cloud infrastructure through declarative APIs. Platform teams compose custom infrastructure abstractions as Compositions and publish them as self-service APIs. It provisions resources across AWS, Azure, GCP, and 200+ providers directly from kubectl. Used by 450+ organizations with 11,000+ GitHub stars.

Twill AI

Autonomous coding agents that ship while you sleep

Twill is an autonomous coding agent platform that implements features, fixes bugs, and ships pull requests without manual intervention. Uses structured workflow of research, planning, human review, implementation in isolated sandbox, AI code review, then merge. Supports custom agent configurations with multiple LLM providers, isolated dev environments for verification, and integrations with GitHub, Linear, Sentry, Notion, and cloud platforms for end-to-end engineering automation.

Terraform vs Pulumi — Declarative HCL vs Programmatic IaC with Real Languages

Terraform and Pulumi are the two most prominent Infrastructure as Code tools in 2026, representing fundamentally different approaches to cloud provisioning. Terraform uses HCL, a purpose-built declarative language with the largest provider ecosystem of 4,800+ integrations. Pulumi lets you define infrastructure in general-purpose programming languages like TypeScript, Python, and Go, bringing full language features to infrastructure management.
