Runs offline

Everything lives on your own network. If the internet drops, your screens keep playing.

Run it from your phone

One controller manages every screen. Change what's showing from any browser.

Free and open

No accounts, no subscription, no cloud. GPL-3.0, and yours to keep.

Uses hardware you have

A Raspberry Pi 4 or 5, or an old 64-bit PC. Plus a screen to plug it into.

One controller. As many screens as you want.

One device is the controller — open its panel from your phone and manage everything. The others are displays that show what you send. Every device runs the same software; you pick the role when you install.

  • ▸A device — a Raspberry Pi 4 or 5, or a 64-bit PC. No desktop needed.An old office computer works well.
  • ▸An operating system — Raspberry Pi OS Lite (64-bit), or Debian 13 on a PC.Free. The guide links to the official installers.
  • ▸A screen — any TV or monitor with an HDMI port.Plus the cable to connect it.
  • ▸Your phone — to open the control panel.Any browser, on the same network.

Three steps to a running screen

1Get an OS on the device. The guide walks you through it with pictures.
2Run the installer. A few lines in a terminal — this is all of it: sudo apt update sudo apt install -y git git clone https://github.com/eximaro/eximaro.git cd eximaro sudo ./install.sh --role display

Rather we set it up for you?

We can supply the devices, configure the controller and every screen, and get you running — a done-for-you service. Prices vary with the devices you choose and how far we travel to you, so the number below is only a rough estimate.

$—estimate

Estimate only — not a quote. Covers a complete Raspberry Pi kit and setup labor for each screen. Travel is billed separately by distance, and your final price depends on the exact devices you choose. We confirm real numbers after you reach out.

  • ▸Devices supplied — we source and prep the Pi or PC hardware.
  • ▸Fully configured — controller and displays paired and ready.
  • ▸On-site setup — connected and tested where you are.
  • ▸A walkthrough — so your team can run it from a phone.

This is a request, not a booking. We'll reply with a real quote. Prices vary with device prices and travel distance for setup.

Thanks — your request is in, and we'll be in touch with a quote. As a reminder, the final price depends on the devices you choose and the travel distance for setup.
