How Cobalt works

From order to TestFlight.

Four steps take you from ordering a Mac to a build in the hands of your testers — no Mac of your own and no local build farm required.

Choose a session

Daily, weekly or monthly

Pick how long you need the Mac for and pay for that window once, in credits. Nothing renews when it ends.

Launch your Mac

When it is handed over

A dedicated Mac mini M4 is set aside for you with Xcode installed. Its AnyDesk ID and password appear under Macs in your account; connect, clone your repo over Git and open the workspace in Xcode.

Build & test

On your Mac

Run your app in the iOS Simulator, profile with Instruments and iterate with live SwiftUI previews.

Ship to TestFlight

From Xcode

Archive in Xcode and upload to App Store Connect with your own account — or install Fastlane and run your lane. Your testers get the build once App Store Connect has processed it.

Device Farm · opens at launch

Test on the real thing

The Device Farm will let you book time on real iPhones and iPads to check gestures, camera, notifications and performance. It is not live yet: nothing can be booked or charged until the device pool opens at launch.

Real iPhone & iPad sessions

Open at launch; until then, test in the Simulator

TestFlight uploads today

Archive in Xcode and upload with your own Apple Developer account

Your signing, your account

Certificates stay in your Apple developer account

Fixed-length sessions, paid in credits

Pick a session length when you launch a workstation, spend the credits for it up front, and the Mac is yours for the whole window — Daily, Weekly, or Monthly, whichever suits the build.
