We needed an autoupdater for our project and decided to emulate Sparkle as closely as possible but to keep it cross-platform.
Here are the bullet points:
  • Licensed under the MIT license
  • Designed for and tested with Qt 4.8
  • Requires updates to be digitally signed
  • Periodically checks for updates
  • Downloads updates to a temporary directory and executes installers (or on mac opens .dmg files), deleting them after install.


Here are some of the things we haven't worked on yet but will once they become more of an issue:
  • Doesn't have a fancy automated install process. Instead relies on installers and direct user intervention (drag-drop .app bundle on mac).
  • Doesn't consider updates delivered over TLS to be safe unless they are also signed (unnecessary redundancy)
