Xeneon Edge widgets: what iCUE gives you, what Xenon adds

The Edge is a good screen with a small widget catalog. Xenon is a free dashboard designed around its exact shape: pages you arrange by hand, controls that act on the PC, touch that never steals a game’s focus, and it runs with or without iCUE.

01What the Edge does out of the box

The CORSAIR Xeneon Edge is a 14.5-inch, 2560×720 touch strip that mounts on a desk stand or in a case where three 120 mm fans would go. Out of the box it is a normal secondary monitor, and iCUE turns it into a widget wall: sensor readouts, a clock, media controls, web pages, and the widgets other people export and share. CORSAIR also publishes a WidgetBuilder kit for people who want to write their own.

That is a good baseline, and for many owners it is enough. The requests that keep coming up in owner forums are the ones iCUE does not answer: a layout you can rearrange by hand, controls that do something on the PC rather than only show a number, touch that does not steal focus from a game, and a way to use the strip without iCUE running at all.

02What Xenon adds

Xenon is a free dashboard that was designed around the Edge's exact shape, short and very wide, before it grew to run on any screen. It runs as a small local service on your PC and shows up on the Edge in one of two ways: as its own full-screen native app, which needs no iCUE at all, or inside iCUE as an iFrame panel if you would rather keep everything in one place.

• Drag-and-drop pages. A grid of resizable tiles, up to eight pages, layouts you can save and share as a code.
• Controls, not only readouts. Mute the mic, switch the audio output, skip a track, mix per-app volume, run a Stream Deck style key grid for apps, OBS, hotkeys and macros.
• Game-safe touch. In the native app a tap on the Edge never moves your mouse away from the game or takes its focus. Only a real native window can ask Windows for that.
• An AI you can talk to. Say what you want on a page and it builds the page. Runs on Google Gemini or on a free local model through Ollama.
• Sensors that go deeper. CPU, GPU, RAM, disks, network, real in-game FPS, plus 24-hour to 30-day history. The temperature readers are the signed ones (PawnIO), never WinRing0.
• Lighting from data. Drive iCUE LEDs from CPU temperature, timers or album art, alongside Govee, LIFX, WLED, Hue and Nanoleaf lights on the network.
• A community catalog. Themes, widget packs and whole page layouts other owners share, installed with one code.

Everything runs locally. There is no account, no cloud and no telemetry; the app checks for updates at launch and reaches the network only for features you switch on.

03Putting it on the Edge

1. Download Xenon-Setup-x64.exe and run it. It installs the native app.
2. The app opens, finds no dashboard engine yet and offers Complete setup. Press it once. This installs Node.js, the sensor readers and the login task, in a window you can read.
3. Xenon asks which screen it should live on the first time it opens. Pick the Edge. It stays pinned there through display changes and sleep.
4. If you prefer iCUE: add a web widget in iCUE pointing at http://127.0.0.1:3030/ and Xenon fills the panel.

04What to know before you try

Two honest caveats. First, the installer is not code-signed yet, so SmartScreen or Defender may warn you the first time; a certificate is being bought and the FAQ explains how to verify the file yourself in the meantime. Second, Xenon is Windows-first. macOS and Linux builds exist and are in beta, and the Edge-specific parts (the reserved touch gesture, the virtual second screen, iCUE lighting) are Windows-only.

It is free and there is no paid version. If you end up using it every day, there is a supporter tier that unlocks a few extra themes and widgets, and that is the whole business model.

05Questions

Does Xenon replace iCUE?

No. iCUE still drives your CORSAIR hardware and its lighting. Xenon runs beside it, either as its own window or inside an iCUE panel, and can send lighting effects to iCUE through its own bridge. You can run Xenon on the Edge without iCUE open, but iCUE is still the thing that configures your devices.

Do I need the Edge to use Xenon?

No. The Edge was the first screen it was built for, but any spare monitor, an old tablet, a phone on the same Wi-Fi or a touchscreen works the same way. See using an old tablet or phone as a PC dashboard.

Can I use iCUE widgets and Xenon at the same time?

Yes. In iCUE the Edge is split into panels; Xenon takes one panel as a web widget and the rest stay as they were. Most people end up giving it the whole strip, but nothing forces that.

Is it really free?

Yes. Free for personal use, source public on GitHub under a non-commercial licence, no trial and no feature locked behind a tier. Supporters get a few extra themes as a thank-you.
