What is it?

UpSnap is a web dashboard for waking up computers and other devices on a local network with Wake-on-LAN. Each device gets a one-click power button, and you can add devices manually or discover them through a network scan using nmap.

Beyond waking devices, UpSnap can check whether a chosen port is open to see if a service is up, track device IP addresses through periodic ARP scans, and shut devices down with a custom command. Cron-based timed events automate these actions. Access is controlled per user and per device, so admins can limit who can view, edit, or power each machine.

UpSnap ships as a single binary, a Docker image for amd64, arm64 and arm variants, and an AUR package. It includes a superuser logs page, support for many interface languages, and a set of light and dark themes.

Key features

  • 01Wake devices from a one-click dashboard using Wake-on-LAN.
  • 02Schedule wake and shutdown actions with cron-based timed events.
  • 03Discover devices through a network scan (requires nmap).
  • 04Track device IP addresses with periodic ARP scans.
  • 05Check whether a specific port is reachable to confirm a service is running.
  • 06Assign per-user, per-device permissions for viewing and power control.

Use cases

  • Waking a home server or NAS remotely over a local network.
  • Powering on lab or office machines on a schedule.
  • Giving family members or colleagues limited power control over selected devices.
  • Running a lightweight self-hosted power panel on a Raspberry Pi.

Quick start

  1. 1

    Download the latest binary from the release page

  2. 2

    Run the server (sudo is needed for Wake-on-LAN)

    sudo ./upsnap serve --http=0.0.0.0:8090
  3. 3

    Or pull and run the Docker image

    docker run --network=host seriousm4x/upsnap:latest

Things to know

  • Wake-on-LAN and network scanning need sudo or host networking, which raises the privilege footprint.
  • The shutdown feature runs commands possibly as root, so the README advises against exposing it to the open web.
