Couchside

Couchside turns your phone into a remote control and game controller for your gaming box. The tool allows you to watch, fix, and control systems running SteamOS, Bazzite, CachyOS, Windows, or a Steam Deck. Built as an open-source service, it operates exclusively over your local network (LAN) without requiring any user accounts. You can manage your gaming PC from your phone with a privacy-focused, subscription-free connection.
