# Edge requirements

:::caution[Preview requirements]
These are the requirements for the current Edge development work, not a final support list.

## Linux host

The current packaging work expects:

- Linux kernel 5.6 or later;
- systemd 248 or later;
- a 64-bit Linux environment supported by the release;
- enough local storage for Edge, its local database, and downloaded content;
- network access to the Tilecast Server.

Debian 12 meets the documented kernel and systemd minimums. Other distributions should only be treated as supported when Tilecast release notes list their required WPE, GStreamer, graphics, and systemd versions.

## Display support

Edge uses WPE WebKit instead of Electron. Development currently covers headless, Wayland, and DRM/KMS renderer paths.

Passing automated tests is not the same as testing a real display. Hardware decoding, rotation, connectors, CEC/DDC, display ownership, restart behavior, and long-running playback still need testing on physical hardware.

## Before using a real screen

Check the release notes for the supported architecture, Linux distribution, WPE/GStreamer versions, renderer backend, codecs, and display-control hardware.

If your machine is not listed as supported, keep using the [current Linux Player](../../players/install-linux/).

## Network

Edge uses the normal Tilecast Player HTTPS and WebSocket APIs. Avahi/mDNS discovery is optional, so manual server entry still works on networks where multicast is blocked.

Use HTTPS for public hostnames. Local HTTP is only for the same trusted-LAN cases supported by the current Tilecast Player.
