Pulumi vs Terraform

Pulumi vs Terraform: the short answer

Pick Terraform if you want the largest ecosystem, the most documentation and an easy hiring story. Pick Pulumi if your engineers would rather write TypeScript, Python or Go than learn HCL. Both do the same job: define cloud infrastructure as code, preview changes and apply them. For a solo developer who already codes daily, Pulumi's free tier is hard to beat.

What is Pulumi?

Pulumi is an infrastructure-as-code tool that defines cloud infrastructure in real programming languages: TypeScript, Python, Go, C# and Java. Your infrastructure becomes ordinary code, with loops, functions, type checking, unit tests and normal code review.

What is Terraform?

Terraform is a declarative infrastructure-as-code tool. You describe resources in HCL files and Terraform plans the changes needed to match. It supports nearly every major cloud and SaaS provider, which is why it became the default. It's now owned by IBM after the HashiCorp acquisition.

Pulumi vs Terraform pricing

Pulumi:

• The CLI and SDK are open source.
• Pulumi Cloud Free is $0 for one user, with state management, Pulumi Deployments, unlimited projects, stacks and updates, and up to 500 workflow minutes. It doesn't limit managed resources.
• Essentials is $40/month with up to 500 managed resources and unlimited users. Pro is $400/month with up to 2,000 resources, SAML/SSO and drift detection. Enterprise is $2,000/month with up to 4,750 resources and self-hosting.
• You can also skip Pulumi Cloud and run your own state backend.

Terraform:

• The open source CLI is free.
• HCP Terraform is priced per managed resource per month: Essentials $0.10, Standard $0.47, Premium $0.99. Enterprise is custom.
• New users get a $500 trial credit. A separate permanent free tier wasn't confirmed, so check the pricing page.

Pricing checked November 2026. For a solo builder, Pulumi's free tier covers hosted state with no resource cap, so it's cheaper to start. The gap closes if you self-host state for either tool, since both CLIs are free.

Key differences

• Language. Pulumi uses your language, so shared helpers and complex logic feel normal. HCL is simpler to read but limited once logic gets involved.
• Testing. Pulumi lets you use standard unit testing frameworks. Terraform testing exists but is less natural for complex setups.
• Ecosystem and docs. Terraform has the larger community, more examples and a big public module registry. A VPC or Kubernetes cluster rarely starts from scratch.
• Hiring. Terraform is easier to hire for. Pulumi suits teams that already have strong application engineers.
• State and pricing model. Pulumi's free tier has no resource cap for one user. HCP Terraform charges per managed resource.
• Plan output. Terraform's terraform plan is the reference point for previewing changes, and its ubiquity makes it familiar to reviewers.

When to pick Pulumi

• Your team writes TypeScript, Python or Go all day and doesn't want another DSL.
• You need loops, conditionals and shared functions in your infrastructure.
• You want unit tests around infrastructure code.
• You're a solo builder who wants free hosted state.

When to pick Terraform

• You want the biggest pool of docs, modules and answers online.
• You're hiring and want people who already know the tool.
• Your infrastructure is mostly straightforward resources where HCL reads clearly.
• Your team already knows Terraform well, so switching has no payoff.

Other options

OpenTofu is the open source Terraform fork, with the same HCL and Linux Foundation governance. If you need to configure servers rather than provision cloud resources, look at Ansible.

Verdict

Terraform is the safer default for teams: more docs, more modules, easier hiring. Pulumi is the better pick when your engineers think in code and you want tests and real logic in your infrastructure. If you're building alone and already write TypeScript, try Pulumi first.
