Frequently asked
Terraform alternatives FAQ
- Is Terraform free?
- The Terraform CLI is free to download and use, and the core language is open source. What HashiCorp charges for is the managed platform around it, such as HCP Terraform, and the vendor publishes those plans on its pricing page. If licence terms are the concern, OpenTofu is a community fork under the Linux Foundation.
- What is the best open source Terraform alternative?
- OpenTofu is the closest match. The project describes itself as a drop-in replacement for Terraform that preserves existing workflows and configurations, and it is stewarded by the Linux Foundation. It supports the same provider and module ecosystem, with the project citing over 3,900 providers and 23,600 modules.
- Can I switch from Terraform to OpenTofu without rewriting my configuration?
- In most cases yes, because OpenTofu is designed as a drop-in replacement that preserves existing workflows and configurations. You should still test state handling and provider versions in a non-production workspace before switching, since the two projects now evolve independently.
- What is the difference between Terraform and Pulumi?
- Terraform uses its own declarative configuration language, while Pulumi lets you define infrastructure in general-purpose languages such as Node.js, Python, Go, .NET, and Java. Pulumi has a free tier for individuals and open source, with the Essentials plan listed at $40 per month including 40 credits.
