Open-source alternative
Replace Terraform Cloud with OpenTofu + Atlantis
The best open-source alternative to Terraform Cloud is OpenTofu or Atlantis, self-hosted on Railway. Infrastructure as code you run. OpenTofu is MPL-2.0; Atlantis is Apache-2.0 PR automation. Terraform is BSL — not the OSS path.
Estimated save $2,400 a year.

FAQ
- Is it free?
- The OpenTofu + Atlantis licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Terraform Cloud seat or task bill on this path.
- Can I migrate from Terraform Cloud?
- Yes. Start with the workflows or data you actually use, then cut over. The OpenTofu + Atlantis stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Terraform Cloud links until they expire.
- How do I deploy it?
- Open the OpenTofu + Atlantis stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: Atlantis + a volume for its data, talking to OpenTofu. Runners that need cloud credentials are often a VPS. No one-click template in this repo yet — Start on Railway. Git hosting can sit on /stacks/forgejo-git.
- What does this replace?
- Terraform Cloud. The published small-team estimate on this stack is $2,400 a year.
