UpSnap

UpSnap is a lightweight web application for waking devices on your local network using Wake-on-LAN. It provides a simple dashboard for organizing devices and triggering actions, with optional network discovery and scheduling.

Key Features

• One-click Wake-on-LAN device dashboard
• Scheduled events via cron for automation
• Configurable port ping checks
• Device discovery using network scanning (requires nmap)
• User management with per-device permissions
• Internationalization support and multiple UI themes
• Runs as a single binary or via Docker images for multiple CPU architectures

Use Cases

• Wake PCs or servers on-demand from a browser on your LAN
• Schedule automatic wake-ups for lab, office, or homelab machines
• Discover and inventory wake-capable devices on a network segment

Limitations and Considerations

• Network discovery requires nmap and typically elevated privileges (root/admin)
• Exposing the service publicly is discouraged due to the risk of command execution misuse; use a VPN for remote access

UpSnap is well-suited for homelabs and small networks that want a straightforward, low-friction way to wake and manage devices. Its simple UI, scheduling, and access controls make it practical for shared environments.
