Open Source

Sparkle is open source software available under the permissive MIT license, and is developed on GitHub by the Sparkle Project with the help of dozens of valued contributors.


Sparkle is kept up to date with the latest Apple technologies such as WebKit 2, Touch Bar, Dark Mode, and XPC. Sparkle 2 supports macOS 10.13 and later.


Supports Sparkle's own EdDSA signatures as well as Apple Code Signing for ultra-secure updates. Sparkle also supports sandboxed applications and authentication for installing in secure locations.


Requires no code in your app, but also provides deep delegate support and plugging in alternative user interfaces for maximum customization. Developers can make Sparkle work exactly as they need, and users can make Sparkle work as they prefer.


Your own branding, icons and app name are used - there's no mention of Sparkle. Works with any macOS app, whether it uses Cocoa, SwiftUI, Qt, Xamarin, or otherwise.


True self-updating - no work required from the user. Users can choose to automatically download and install all updates silently in the background. Developers can use an included tool to automatically generate smaller and faster delta updates between releases.

With Sparkle, you're in good company. Here are just a few of the thousands of apps which use Sparkle
