About Atlantis

Atlantis is an open-source automation tool designed to streamline Terraform workflows by integrating infrastructure management directly into pull requests. It enables DevOps teams to execute terraform plan and apply commands through comments on GitHub or GitLab, fostering a collaborative GitOps environment. By centralizing infrastructure changes within version control, Atlantis ensures that all modifications are peer-reviewed, auditable, and consistent. This tool is specifically built for engineering teams seeking to reduce manual overhead while maintaining strict governance over their cloud infrastructure deployments through automated, transparent, and reproducible processes.
