Terraform uses HCL. Both deploy AWS resources — but the approach, ecosystem, and tradeoffs are very different.

This matters more than most comparisons admit.

Workspaces isolate state for the same configuration. Stacks orchestrate multiple configurations as a single deployment. Here’s when to use each. Core Difference in 30 Seconds Workspaces: One Terraform configuration → multiple isolated state files (dev, staging, prod). Stacks: Multiple Terraform configurations → one coordinated deployment (networking + database + compute). Workspaces: main.tf ──→ dev.tfstate ──→ staging.https://www.terraformpilot.com/articles/cloudformation-vs-terraform-2026/Sun, 12 Apr 2026 10:00:00 +0000https://www.terraformpilot.com/articles/cloudformation-vs-terraform-2026/This is the most common IaC decision for AWS teams. Both are mature, production-ready tools — but they solve the problem differently. Here’s an honest 2026 comparison.

The community forked Terraform as OpenTofu under the Linux Foundation. In 2026 — with IBM’s acquisition of HashiCorp complete and OpenTofu at version 1.9 — the two projects have diverged enough that the choice matters. Here’s an honest comparison.
