Elgato has introduced digital Stream Deck buttons for desktop users as part of its “Stream Deck Everywhere” initiative. The feature is now available in beta form and can be accessed by users who already own a Stream Deck or compatible Corsair peripherals. Unlike the mobile app version, this software doesn’t require an additional subscription fee. This move aims to satisfy the long-standing demand for digital Stream Deck buttons on desktops.
