Splay sends each Mac app, and each browser tab, to the output you choose. Music on the AirPlay speaker, the call in your AirPods, everything else on the Mac. Drag, drop, done.
macOS plays everything through one output. Splay gives each output a lane and lets you drag any app, or any single browser tab, into it. It keeps playing there until you move it back.
Splay does one job, routing sound, and does it with care. It skips the plug-in rack and the settings maze.
Other per-app tools treat Chrome as one app. Splay's companion extension lists every tab that's playing, so the lecture goes to your headphones while the radio tab keeps playing on the speakers.
Send one app to an AirPlay speaker while the rest of the Mac stays on the Mac. Volume keys follow the speaker.
Click a chip to mute it. Each lane's slider is that output's own volume.
Pin an app and it returns to its output every time. If the speaker drops out, Splay goes quiet instead of blasting your laptop, then picks up again when it's back.
Each lane shows the Spotify or Music track playing in it, so you always know what's going where.
Splay uses macOS's own audio capture. It installs no driver or helper, keeps audio in memory only, and has no account.
SoundSource is excellent, with EQ, effects and Audio Unit plug-ins. If you mostly want each app on the right speaker, Splay does that for £5, and handles browser tabs one by one.

SoundSource is a trademark of Rogue Amoeba Software. Splay is not affiliated with Rogue Amoeba. Their price is from rogueamoeba.com, October 2026.
No subscription and no account. Try it for a week, then keep it for the price of a coffee and a biscuit.
Free during the beta. Splay updates itself, and beta testers will be first to hear about launch.
macOS on its own plays every app through one output. Splay adds per-app output: open it from the menu bar and drag an app, such as Spotify, into the lane for the speaker or headphones you want. Every other app stays where it was. There's a step-by-step guide covering the built-in options too.
Splay does SoundSource's core job, sending each app to its own output with its own volume, for £5 once instead of $49. It also routes single browser tabs. It has no equaliser or audio effects, so if you need those SoundSource is the better choice. See the full comparison.
Yes. Splay's companion extension for Chrome and other Chromium browsers shows each tab that's playing as its own chip, which you can drag to any output. Most per-app tools, SoundSource included, can only move the whole browser.
No. Splay uses the audio capture built into macOS 26, so it installs no driver, virtual device or system extension. You don't need to set up a Multi-Output Device in Audio MIDI Setup either.
No. Sound passes through memory on its way to the output you picked and is never written to disk or sent anywhere except that output. There's no account and no analytics.
Macs with Apple Silicon running macOS 26 or later. Splay relies on the audio capture Apple added to recent macOS, which is why it needs no driver.
Splay sends standard AirPlay audio to one speaker at a time, and is tested with AirPort Express. Other speakers and receivers that accept AirPlay without a password should work; HomePod and Apple TV aren't supported yet. Tell us what you try.
Splay comes with a small extension for Chrome and other Chromium browsers. Splay walks you through installing it, then playing tabs appear as their own chips you can drag anywhere.
The beta isn't notarised by Apple yet, so macOS asks you to confirm it once. Open it, then choose Open Anyway in System Settings › Privacy & Security. The paid release will be notarised.
Quit Splay from its menu-bar icon and move it to the Bin. It installs nothing else, so there's nothing left behind but your saved preferences.
