The UltraBar X is a modular desktop command center/smart-hub built around an ultra-wide “CoreBar” touch display with a system of magnetically attachable input modules. Designed as an intelligent hub for Windows, macOS, and Linux environments, it also works as a smart home controller. With a 45-degree ergonomic tilt, wireless PC wake, smart-home integration, and modular touch/mechanical inputs, it gives creators, gamers, and power users quick access to all key functions.
The whole system is built around the CoreBar hub and modular add-ons like VivoCube, DotKey, SenseCube, and KnobKey, all of which use the QuantumLink magnetic protocol for instant attachment and auto-detection. The CoreBar hub features a 5:1 touch display, LineOS firmware, Bluetooth Mesh, USB/HID connectivity, and an AI-driven SceneShift engine that adapts UI layouts and macros to different workflows.
The four optional modules add AMOLED touch controls, Cherry MX keys, rotary knobs, and multi-sensor environmental sensing (mmWave radar, light, temperature, humidity, vibration). Other features include support for Smart Home systems like Philips Hue, SONOS, and Home Assistant, and offer an app store with 90+ platforms and 300+ templates. UltraBar X can connect up to 15 modules, enables wireless PC wake and one-tap power-on (via an optional boot module), and provides a developer SDK for custom plugins and extensions.

UltraBar X runs on LineOS, a modular operating system with a fully customizable UI, dynamic themes, and real-time system data visualization. The built-in SceneShift AI engine enables context-aware automation, adapting layouts, controls, and interactions based on active applications and user workflows. LineOS supports advanced control features, including macros, shortcuts, multi-step actions, and workflow automation, all configurable through cross-platform management apps for Windows, iOS, and Android, with macOS support currently in development.
The ecosystem includes a built-in Nexus Store offering 90+ platform integrations and over 300 templates for instant, drag-and-drop customization. Users can sync profiles across devices, edit configurations remotely, and deploy changes instantly. UltraBar also advertises an open SDK for developing custom plugins, scenes, and integrations. But, at this time, the company has not provided any public documentation, developer portal, GitHub repository, or SDK for the device.
UltraBar X also adds several small but useful features as it reconfigures in 0.3 seconds with cable-free magnetic modules, supports endless UI themes, and uses a 45° tilt designed to reduce neck strain. VivoCube can work as a standalone mini display, and the system supports up to 15 mixed modules with color choices collected after the campaign. It has been showcased at IFA Berlin and the Eletrolar Show, uses eco-friendly manufacturing processes, and its Nexus Store continues to receive new plugins, scenes, and themes for ongoing expansion.
Another feature of the product is Remote Power-On Control, for which the company provides both Home Assistant integration and an optional PCIe-based wireless boot module. This allows users to trigger PC startup through their smart-home system or via the dedicated PCBooT card that simulates the physical power button using Bluetooth Mesh. Mac systems are supported through Wake-on-LAN for Ethernet models or instant wake from sleep via USB key-press simulation for Wi-Fi-only Macs.
Previously, we have written about various macro keyboards like the DuckyPad Pro and the Waveshare MK20 macro keyboard, among others, but feature-wise, the UltraBar X is in a league of its own. It’s also pricier.
The UltraBar X is available on Kickstarter, with prices starting at HK$2,246 (~$289) for the Early Bird Core Set and going up to HK$3,647(~$469) for the All-in-One Pack. Shipping will be charged later through a post-campaign survey, and orders are planned to ship in April 2026. The campaign is fairly successful so far, with over $150,000 US raised for more than 340 backers.
