Conveyor makes distributing desktop and command line apps as easy as shipping a web app. It's a tool not a service, it generates and signs self-upgrading packages for Windows, macOS and Linux using each platform's native package formats without requiring you to have those operating systems, and it looks like this:


  • Create packages for every OS on any OS. Conveyor implements everything itself so doesn't rely on platform native tooling.
    • Build applications that use the built-in Windows MSIX package manager.
      • Windows keeps them up to date in the background.
      • Installs and updates reuse data blocks and hard link files, even between apps from different vendors.
      • Has everything IT departments need to easily deploy to managed networks.
    • Build Mac applications that automatically use the popular Sparkle 2 update framework, without code changes.
    • Build apt repositories for Debian/Ubuntu, tarballs for other distros. Integrates with systemd for servers and cron jobs.
  • Support for Electron apps. (beta!)
    • Benefit from well maintained platform native software updates without relying on Squirrel or any centralized update servers.
  • Deep JVM support.
    • Bundles a JVM from a vendor of your choice, and then uses jlink/jdeps to minimize the size.
    • Uses a native launcher that adds useful features.
    • Import configuration from Maven and Gradle.
  • Automatic icon conversion.
    • Supply a set of PNGs and Conveyor turns them into the platform specific formats for you.
  • Generates download sites.
  • Brainless code signing.
    • Sign your Windows/Mac downloads for a better UX, or ignore it and get self-signed packages with a curl | bash style install.
    • You can sign and notarize on any OS.
    • You can back up your single root key by writing it down as words on paper.
  • Pre-made template projects for native C++, Electron, JavaFX (JVM) and Jetpack Compose Desktop (JVM).
  • Pierce the abstraction! Cross-platform tooling doesn't mean giving up platform-specific features. Over 120 different settings let you precisely configure your packages, including your:
    • Mac Info.plist files.
    • Windows manifests.
    • Linux .desktop files and package install/uninstall scripts.
