Atlas

Atlas is a containerized tool for discovering, analyzing, and visualizing network infrastructure. It scans local subnets and Docker containers, stores findings, and presents them through a web UI backed by an API.

Key Features

• Multi-interface and multi-subnet network discovery with configurable scan ranges
• Docker host scanning via Docker socket inspection, including multi-network containers
• Fast scans (ARP/ping) plus deeper enrichment such as open ports and OS fingerprinting
• Interactive, real-time network graph visualization and host table views
• Scheduled scanning with configurable intervals and runtime interval management via API/UI
• SQLite persistence for discovered hosts, interfaces, and scan results
• REST API with interactive documentation for accessing hosts and scheduler controls

Use Cases

• Homelab visibility: map devices, services, and container connectivity at a glance
• Lightweight infrastructure monitoring: detect new hosts, IP changes, and exposed ports
• Troubleshooting networking issues: understand multi-NIC and multi-network relationships

Limitations and Considerations

• Requires elevated network capabilities (for example raw socket access) to perform discovery scans
• Docker inspection requires access to the Docker socket, which has security implications

Atlas combines a Go-based scanning engine, a FastAPI backend, and a React UI served behind Nginx to provide an approachable, continuously updated view of your network. It is suited to environments where quick discovery and clear visualization are more important than heavyweight enterprise NMS complexity.
