OpenTofu Review

Worth it

Should I use OpenTofu?

OpenTofu - Modern Infrastructure as Code - opentofu.org

· 1 month ago

Adopt it if your team manages cloud infrastructure and wants Terraform compatibility with no license fees or lock-in risk. Skip it if you don't write infrastructure code or need paid vendor support contracts.

Confidence

Best for

  • Teams burned by HashiCorp's license change
  • Existing Terraform users wanting a drop-in swap
  • Cost-sensitive teams at scale
  • Platform teams needing state encryption

Not for

  • Non-engineers — CLI tool, no friendly dashboard
  • Teams needing vendor SLAs or support contracts
  • Solo devs with one small server — IaC is overkill
  • Shops standardized on paid Terraform Enterprise workflows

Gotchas - check before you buy

high

State files contain secrets; you must configure encryption and a secure backend yourself

medium

Tool is free, but management platforms (Scalr, env0, Spacelift) charge per-run for team features

medium

DoS and path-handling CVEs in 1.9–1.11; keep patched to at least 1.11.7

medium

No vendor to call when a release breaks your pipeline; support is community forums
