Free for Mac in beta

Your music, on top of every game.

aux is the music overlay for games. It floats over whatever you play and shows your Spotify or Apple Music song, so you can skip, sing along and show your friends what's on without ever alt-tabbing.

Works with Spotify and Apple Music. No logins.

01 · Pixel pets

It has pets. Obviously.

They walk the player, ride the mini pill and nap when you pause. Your first one hatches from an egg. Poke this one.

Seven pets are free, forever. The rest come with worlds.

02 · Worlds

No coins. No loot boxes. Just worlds.

A world is the only thing aux sells. Pay once, it's yours for good on Mac and PC, and there's nothing random about it. Try one on first.

05 · Specs

Will it tank my FPS? Nah.

aux runs next to games, so it's built to stay out of the way. Here's the sheet.

Your game
Never touched.
No injection, no hooks into DirectX, no keyboard or mouse hooks. It just floats on top.
PC
One small exe.
Native Rust, no runtime. Budgets: under 30 MB of memory and under half a percent of CPU while playing.
Mac
macOS 13 or later.
About 3% CPU for the plain overlay. Live visualizers need macOS 14.2.
Over a match
Mini mode.
No visualizer, no audio analysis, almost invisible. It turns on by itself for fullscreen games.
Music
Spotify, Apple Music.
Plus SoundCloud in a browser tab on Mac. No logins: aux talks to the app you already have.
Your audio
Stays put.
Analyzed live for the visualizers, never recorded or sent. Lyrics are looked up by song name.
Controllers
PlayStation, Xbox.
The touchpad is the album; Options and the D-pad do the rest.
Price
$0 in beta.
The whole overlay and seven pets are free. Worlds are $2.99 each, if you want them.

PC numbers are aux's own budgets, measured on every build.

06 · FAQ

Before you ask.

When can I get it?

aux is in private testing right now. Join the waitlist and we'll email you the moment the beta opens. It's free during the beta.

Is it actually free?

Yes. The whole overlay and all seven starter pets are free. Worlds are optional: $2.99 each, a fixed price with nothing random, and yours for good on Mac and PC.

Does it work in fullscreen games?

Yes. It floats over fullscreen games, lets your clicks through, and switches to mini mode on its own so it's barely there mid-match.

Is there a Windows version?

Yes, built from scratch to be lighter than a browser tab. It's in testing alongside the Mac one, and Mac and PC friends see each other.

Does it work with Apple Music?

Yes, with no sign-in. aux follows Spotify or Apple Music, whichever you last pressed play in, or stick it to one in Settings.

Is there a Spotify overlay for Mac games?

That's aux. Spotify's own overlay only exists on Windows, through Xbox Game Bar or the Steam overlay. aux runs on macOS 13 or later and floats over any Mac game, with Spotify or Apple Music. More on aux for Mac.

How is it different from the Xbox Game Bar Spotify widget?

Game Bar's widget is a small Spotify remote you open with Win+G, and it only works on Windows with Spotify. aux stays on screen by itself, shrinks to mini mode mid-match, works with Apple Music too, and adds synced lyrics, listening along with friends and visualizers. The full comparison.

Can anti-cheat ban me for it?

aux never touches your game: no injection, no DirectX hooks, nothing loaded into the game. It's a separate window drawn on top, like a chat app's notification. On PC, while the Hub is open over a game, aux briefly watches the mouse so clicks on the Hub don't reach the game; it's off whenever you play.

Why does the Mac ask for permissions?

Once to control your music app (so the buttons work) and once for audio (so the visualizers react). Audio is analyzed live and never recorded.

Your next match needs a soundtrack.
