zsign is a fast, cross-platform open-source alternative to Apple's codesign tool for re-signing iOS .ipa packages, Mach-O binaries, and .app bundles with custom certificates and provisioning profiles. It runs on macOS, Linux, Windows, Android, and FreeBSD without requiring Xcode, and supports dylib injection and bundle metadata editing.

Use cases

• re-sign an ipa with a new certificate without a mac
• inject a dylib into an ios app
• sign ios apps in a linux ci pipeline
• change bundle id and display name of an ipa
• inspect certificates in a p12 or mobileprovision file
• ad-hoc sign an ios app for distribution
• remove app extensions from an ipa bundle

When to choose

• you need to re-sign iOS apps on Linux or Windows servers without Xcode
• you want fast repeated signing with caching of unchanged Mach-O binaries
• you need dylib injection or bundle metadata editing alongside signing
• you are automating iOS app re-signing in CI/CD pipelines

When to avoid

• you need full Apple codesign compatibility or notarization for App Store submission
• you only sign on macOS and are happy with Apple's official codesign tool
• you need a GUI workflow rather than a command-line tool
