90 seconds. The whole platform.

The Problem

Every screen category is a dead end

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.

One Screen, One Purpose

Every existing solution forces you into a category. A signage player. A kiosk browser. A dashboard. No composability. No real programmability.

Platform Lock-in

Most solutions work on one platform only. Want to use iPads AND Android tablets AND Apple TVs? Good luck.

Cloud Dependent

Subscription-based cloud services mean your displays stop working if the internet goes down. Your data lives on someone else's servers.

Core Innovation

A real windowing system for every screen

KingKiosk brings true multi-window compositing to any display surface. Create complex layouts with floating or tiled windows, each independently programmable via MQTT.

Web Browser

Weather

Camera Feed

Clock

Gauge

Floating Windows

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.

Drag, resize, minimize, maximize
Z-index layering and transparency
Smooth animated transitions
All controllable via MQTT

Dashboard

Calendar

Clock

Weather

Gauge

i3-style Tiling

Automatic grid layouts where windows intelligently split available space. Add a window and the layout recalculates. No manual positioning needed.

Automatic space-filling layouts
Grid, columns, and rows
Smart window splitting
Keyboard and MQTT layout control

Screen Presets

Save entire layouts as named presets. Switch between "Morning Dashboard", "Movie Mode", and "Security View" with a single MQTT command.

Save/recall named layouts
One-command switching
Fleet replication across displays
Per-display or group-wide presets

Fleet-wide schedule deployment

Architecture

MQTT-native from the ground up

Every widget, every setting, every pixel is controllable via MQTT. This isn't a bolt-on integration. MQTT is the nervous system of KingKiosk.
