## What the models said for it

- "Terraform is often the safest choice for mid-market companies because it offers flexibility, a mature ecosystem, strong community support, and cloud-agnostic capabilities" (Claude Haiku 4.5, IaC)
- "For most mid-sized B2B companies, Terraform is the safest and most flexible choice due to its maturity, multi-cloud support, and extensive ecosystem." (Mistral Small, IaC)
- "For a typical mid-market B2B company, I'd usually start with Terraform — or OpenTofu if you want an open-source, community-governed alternative." (GPT-5.4 mini, IaC)
- "It is considered the industry benchmark for IaC tools and offers declarative provisioning across all major clouds and on-prem environments." (Llama 4 Maverick, IaC)

## And against it

- "Avoid starting new projects with: 1. Terraform under BSL (use OpenTofu instead)" (Kimi K2, IaC)
- "HashiCorp changed Terraform’s license from the open-source MPL 2.0 to the restrictive Business Source License (BSL)... raises long-term concerns about price hikes" (Qwen 3.7 Flash, IaC)
- "Terraform's 2023 licensing change to BUSL-1.1 (no longer open source) and inherent limitations with domain-specific languages create challenges" (Claude Haiku 4.5, IaC)
- "To avoid paying for expensive SaaS management platforms (like Terraform Cloud or Spacelift), self-manage your state files" (Gemini 3.5 Flash, IaC)
