Cobalt
For app agencies

More clients, no more Macs to buy.

Run every client's iOS and macOS build on its own cloud Mac. Every session is listed in your account's usage log with its date and price, so you can bill it back cleanly.

How it works

Run every engagement on its own Mac

A separate Mac per client, fixed session prices, and expert help from launch — built for client work.

One isolated Mac per client project

Order a dedicated Mac mini M4 for each client and sign in to that client's Apple account on it alone, so repositories and signing never mix.

Each client's signing on its own Mac
Named after the client, attached to its project

Mac time you can bill back

Every session has a fixed price in credits, paid when you launch it, and your usage log lists each one by date. Attach each Mac to its client project to see which Macs work for whom.

Same price per credit at any amount

Overflow with App Experts

Deadline creeping up? When the App Experts marketplace opens, you can bring in an iOS or macOS engineer to work on the same Cobalt Macs, paid in credits.

Opens at launch
SwiftUI, UIKit & submissions
No new contracts to sign

Isolated machines

Each session is its own physical Mac, reached over AnyDesk's encrypted connection.

Scale for crunch

Add workstations the week before a launch, drop them after.

Client-ready builds

Upload to TestFlight from the client's own App Store Connect account, so they try builds on their own devices.

Built for how agencies work

Top up any amount for client work — the price per credit is the same whether you add a little or a lot.
