Atlantis pros and cons
Free and open-source (Apache 2.0) with thousands of production deployments — the most battle-tested Terraform PR automation workflow available.
PR-comment-driven workflow (`atlantis plan`, `atlantis apply`) is simple, auditable, and requires no new UI to learn — all workflow happens in the existing code review process.
Workspace locking prevents concurrent applies to the same Terraform workspace — the most common cause of Terraform state corruption in team environments.
Simple YAML configuration and well-documented setup makes initial deployment straightforward compared to building equivalent CI/CD pipeline logic from scratch.
Self-hosted only — requires a server to run Atlantis and webhook configuration for each repository, with ongoing maintenance responsibility.
Does not scale as cleanly as managed platforms for very large numbers of stacks — teams with 100+ stacks often outgrow Atlantis and move to Spacelift or Terraform Cloud.
