Overlays for your game screen
OniX lays a transparent overlay on top of your game — soft frames, borders, and small details — without ever covering the stats you actually need.
Themes save automaticallyHow it works
Set it up once — every overlay stays exactly where you left it, per game.
Enter your width and height, or let OniX detect them for you. Every overlay scales to match your screen.
Valorant, Fortnite, Overwatch, Marvel Rivals, or Dead by Daylight — each one has its own overlay library.
Drag the overlay you like into place, save it, and it appears automatically every time you launch the game.
Themes
Every theme ships as layered, transparent PNGs, shown here with a clear background so you can see exactly what sits on top of your game.
Cat-ear frames, a paw-print border, and pink ribbon corners — built for hero portraits, health bars, and the kill feed.
The same sakura shapes in a cooler palette — pale blue florals next to blush ribbon, for a calmer look on stream.
A round paw-print frame for hero portraits or a webcam.
A lighter cut of the sky set, made for minimal HUDs.
A paw-print ring that can double as a cooldown or charge indicator.
Why OniX
Light on your machine, easy to set up, and easy to forget it's even running — until you glance at your stream.
Overlays are transparent PNG layers, so nothing you actually need to see on screen ever gets covered.
Each supported game gets its own page and its own set of overlays, kept separate from the rest.
Detect your screen size once, and every overlay scales itself to match, no manual resizing.
Arrange an overlay once — OniX remembers its position for the next time you open that game.
The library grows on a regular schedule — pink and sky today, more palettes on the way.
Already have artwork you like? Upload it as an image and use it exactly like a built-in overlay.
Inside the app
Open a game, add an overlay, and you're done — the whole flow lives on one page.
The Valorant page, showing an empty overlay slot ready for your first upload. Every other supported game follows the same layout.
