Why the models rank Terraform — on best infrastructure-as-code tool
“Still the default for a reason — the broadest provider ecosystem by far (thousands of providers, every major cloud and SaaS), a decade of battle-tested state management, the deepest module registry, the largest hiring pool, and mature surrounding tooling (Terraform Cloud/HCP, Sentinel policy, drift detection); near-tie with OpenTofu at #2, ranked first only on ecosystem inertia and vendor/provider support still landing here first”
