Fader - Per-app volume & audio routing for Mac, simple key controls.

by•
Windows has had a per-app volume mixer for 15 years. macOS still doesn't. Fader fixes that: set any running app's volume straight from your keyboard — one letter per app — route each app to its own output device, and save mixer setups you can recall instantly. It lives in your menu bar, handles up to 10 apps at once, and is fully App Store sandboxed — no cloud, no account, no audio drivers to install.

Hi I'm Jay, the creator of Fader - System Audio Mixer. I kept hitting the same wall on my Mac: turn the volume down and everything drops — the call, the music, the alert, all at once. Windows has had a per-app mixer forever; macOS just... doesn't. Every workaround was a clunky utility or a hardware controller. So I built Fader — hold a key, type the app's first letter, set its level. Route Zoom to your headphones and Spotify to your speakers. Save a setup for "calls" and one for "focus." It's a sandboxed App Store app, no drivers, nothing phones home. 3 Days free trial, then $19.99 once. Would love to hear which apps you'd map first.
