GitOps automation for Docker Compose on a single Docker host. Oar watches a Git branch, runs docker compose to apply updates, and records deployment results for review in the CLI or web UI.

• Single binary exposing the CLI and web dashboard.
• Tracks project configuration on disk and can encrypt stored secrets when an encryption key is provided.
• Automatically reconciles Docker Compose projects without manual intervention.

• Docker Engine with the Docker Compose plugin on a Linux host.
• Network access from the host to your Git remote.

Oar is designed as ArgoCD for Docker Compose - bringing GitOps automation to environments where Kubernetes complexity isn't needed or justified.

• Home labs and personal projects - Simple single-server deployments without operational overhead
• Demo environments - Fast setup and teardown for rapid prototyping and demonstrations
• Development and staging environments - Quick deployment cycles without production-grade complexity
• Small-scale applications - Projects that don't require multi-node orchestration or enterprise features
• Learning environments - Educational setups where Docker Compose is more approachable than Kubernetes
• Side projects and experiments - Personal or small team projects where simplicity trumps scalability

• You need GitOps but not the complexity of Kubernetes
• Downtime during deployments is acceptable (rolling updates not required)
• You prefer Docker Compose's familiar syntax over Kubernetes manifests
• You want automated deployments without managing a full cluster
• You need something that "just works" on a single host
