Not digital signage. Not a kiosk. A new category. A runtime that turns any screen into a remotely programmable display surface. Send commands and compose layouts from 25+ widgets. Control everything in real-time. Multiple platforms.
Digital signage just loops slideshows. Kiosk software locks to one app. Dashboard tools can't manage displays remotely. Smart home panels lack a real windowing system. You've been forced to choose a category. Until now.
Every existing solution forces you into a category. A signage player. A kiosk browser. A dashboard. No composability. No real programmability.
Most solutions work on one platform only. Want to use iPads AND Android tablets AND Apple TVs? Good luck.
Subscription-based cloud services mean your displays stop working if the internet goes down. Your data lives on someone else's servers.
KingKiosk brings true multi-window compositing to any display surface. Create complex layouts with floating or tiled windows, each independently programmable via MQTT.
Position windows anywhere with pixel-perfect precision. Stack with z-index control, set per-window opacity for overlay effects. Drag and resize with smooth animations.
Automatic grid layouts where windows intelligently split available space. Add a window and the layout recalculates. No manual positioning needed.
Save entire layouts as named presets. Switch between "Morning Dashboard", "Movie Mode", and "Security View" with a single MQTT command.
Automatically switch layouts based on time of day and day of week. Your display adapts to your routine without any manual intervention.
Every widget, every setting, every pixel is controllable via MQTT. This isn't a bolt-on integration. MQTT is the nervous system of KingKiosk.
