Mach uses intelligent caching to deliver up to 5× faster builds — without ever retaining your source code on the build server. No setup required. It just works.

Why Builds Are Fast

Smart Dependency Caching

Dependencies are intelligently cached between builds. Only changed packages are updated — saving minutes on every build.

Incremental Compilation

Xcode and Gradle leverage incremental build caches per project. Only recompiles what actually changed.

Zero-Config Acceleration

No configuration needed. Caching is automatic from your very first build. Subsequent builds are up to 5× faster.

Security Commitments

Zero Source Retention

Your source code is automatically deleted after every build. No proprietary code remains on the build server — ever.

Secrets Never Touch Disk

Signing certificates, keychains, and environment secrets are cleaned after every build. Secrets exist only in memory during the build.

Sanitized Build Logs

All secret values are automatically scrubbed from build logs before they reach the Dashboard. No accidental leaks.

Private Artifact URLs

Install links use Mach public file routes such as files.getmach.dev, so users do not see raw S3 bucket or presigned URLs.

Only Public Packages Cached

The only data retained between builds is open-source packages from public registries (npm, CocoaPods). Nothing proprietary.

Trust & Transparency

Mach is built for teams that take security seriously. After every build completes, you'll see this confirmation in your build logs:

🔒 Security: No source code retained on build server. Only public dependencies cached.

This isn't just a message — it's enforced by the build system architecture. Source files, build outputs, and all signing materials are physically removed after every build.
