A build server for iOS
that just works.

There's no way around it — iOS builds need macOS.

Apple requires that iOS, iPadOS, watchOS, and macOS apps are built using Xcode on a Mac. There's no Linux cross-compiler, no Windows workaround. Your CI/CD pipeline needs a real Mac at the end of it.

For many teams, that means one of these compromises:

• A Mac under someone's desk. It works until it doesn't — power cuts, macOS updates, disk full, and nobody notices until the build fails at 2am.
• A Mac mini at home. Better, but you're still responsible for uptime, monitoring, and connectivity.
• GitHub Actions macOS runners. Expensive at scale (£0.08/min for Apple silicon), and you're sharing resources with other builds.
• AWS EC2 Mac. Powerful but complex — 24-hour minimum billing, Dedicated Host management, significant DevOps overhead.

SSH in, set up your pipeline, forget about the hardware.

Every Halfpenny Mac comes with full root access on a dedicated Apple silicon Mac mini. Install Xcode, set up fastlane, configure your CI runner — exactly as you would on any Mac, because it is a real Mac.

Common setups our customers run:

• GitHub Actions self-hosted runner — point your workflows at your Halfpenny Mac and run builds on dedicated hardware instead of shared runners
• GitLab CI runner — register your Mac as a GitLab runner for macOS builds
• Fastlane + match — code signing, screenshots, App Store submissions, all automated
• Xcode Cloud alternative — more control, no Apple lock-in, and you can install whatever you need
• React Native and Flutter builds — the iOS side of your cross-platform app

Tailscale gives you secure SSH access from anywhere. No port forwarding, no VPN setup, no public IP.
