Every Terraform change becomes a pull request with Atlantis, which runs the plan on your server, posts the output for review, and applies only the exact change reviewers approved. Open a pull request that touches Terraform code and Atlantis automatically runs terraform plan, posting the full output as a comment and a commit status your reviewers can inspect line by line. When the change looks right, a teammate comments atlantis apply and Atlantis executes the exact plan that was reviewed, then reports the result back on the same pull request. Each directory and workspace is locked while a pull request is open, preventing two changes from applying out of order, and locks can be inspected or discarded from the web interface. Apply requirements let you demand an approved review or a mergeable branch before anything runs, and optional policy checks evaluate plans against your rules before they can proceed. Repositories describe their projects, workspaces, and custom workflows in an atlantis.yaml file, including pinned Terraform versions, execution order groups, and parallel planning or applying across projects. Because Atlantis runs inside your infrastructure, cloud credentials never leave your network, and every plan, approval, and apply is preserved on the pull request as an audit trail.
