The Challenge

Code signing shouldn't require a PhD

Developers spend hours wrestling with cryptic tools, confusing documentation, and arcane command-line incantations. There's a better way.

Without KestrelSign

  • Hours spent deciphering codesign, notarytool, and signtool documentation
  • Cryptic error messages with no clear path to resolution
  • Manual inside-out signing for complex app bundles
  • Waiting for notarization with no progress visibility
  • No audit trail when something goes wrong

With KestrelSign

  • Guided setup wizard detects certificates and configures everything
  • Clear error messages with actionable remediation steps
  • Automatic inside-out signing handles complex bundle structures
  • Real-time progress tracking through notarization queue
  • Comprehensive logs and HTML reports for every operation
