Notarize from Windows or Linux

The last step of cross-compiling is the only one that needs macOS.

Route

Cross-compiling a macOS build from Windows or Linux is solved — electron-builder, Tauri's CI, Godot exports all produce a .app without a Mac. Then distribution stops cold: signing and notarization refuse to run anywhere but macOS.

macbuild is that missing last step. Upload the unsigned zip; Apple hardware runs the codesign → notarytool → stapler chain and returns an artifact your macOS users can open without right-click tricks.

From git push to TestFlight.

Connect your repo

Sign in with GitHub and point macbuild at your Flutter, React Native, or Xcode repository.
git push origin main
macbuild builds on real Macs

Your code builds and signs on Apple hardware with your App Store Connect key — you watch the logs live.
xcodebuild archive · sign
TestFlight, done

The signed IPA uploads to TestFlight automatically. You get an email; your testers get a build.

What you get

Auto-detects your stack

pubspec.yaml → Flutter. package.json + ios/ → React Native. A root .xcodeproj → bare Xcode. Zero config unless you want it.

Live build logs

Stream xcodebuild output in your browser while the build runs — no guessing what broke.

Cached, fast rebuilds

Per-project pub, node_modules, and DerivedData caches. Cached rebuilds target under 15 minutes.

Your keys stay yours

Sign with your own App Store Connect API key — encrypted at rest, decrypted only into an ephemeral keychain per build. macbuild never stores p12s.

Artifacts, signed & temporary

IPAs and dSYMs land as signed download links, expiring after 7 days. Nothing lives forever.

Notified, not nagged

Email or Slack when a build finishes or fails. Watch it live if you'd rather.

Questions

Which build tools does this work with?

Anything that produces a .app bundle inside a zip — Electron (electron-builder), Tauri, Godot, Unity, or a plain SwiftPM release build from CI.

Is my binary executed on your machines?

No. Uploads are untrusted input: validation uses non-executing tools only, and the build pipeline never runs your artifact's code.

What does it cost?

$7 per notarized artifact through the same credit wallet as builds — one free probe a month to try it.
