## Description

Atlantis is a GitOps deployment tool and infrastructure as code orchestrator that synchronizes cloud resources with a git repository using pull request comments. It serves as a policy-based infrastructure gate and automation system for Terraform, executing plans and applies directly from version control to coordinate deployments across multiple projects and environments.

The system differentiates itself through a lock-based concurrency model that prevents simultaneous modifications to the same project or workspace. It features server-side policy validation to intercept plan outputs for compliance checks and dynamic binary provisioning to manage specific tool versions based on project requirements.

The platform covers a broad range of capabilities including automated infrastructure planning, project dependency management, and custom workflow execution via user-defined scripts. It also provides security controls for repository access, command execution restrictions, and real-time execution log streaming.

Integration is handled through version control system webhooks and supports status notifications via Slack.
