WinSparkle is an app update framework for Windows desktop applications, inspired by Sparkle for macOS. It ships as a single dependency-free DLL with a C API, checks appcast (RSS) feeds for new versions, and presents a native update UI with EdDSA-signed update verification.

Use cases

add automatic updates to a Windows desktop app
check for new versions via an appcast feed
sign and verify software updates with EdDSA
ship an updater DLL with no runtime dependencies
integrate update checking from C#, Python, Go, or Pascal
show a native update prompt without tying into a UI toolkit

When to choose

you distribute a Windows desktop application and need Sparkle-style auto-updates
you want a small, MIT-licensed, toolkit-independent updater with a C API
you already publish Sparkle appcasts and want Windows compatibility

When to avoid

your application is not on Windows
you need a full deployment/patching system rather than simple update checks
you cannot host an appcast feed or sign updates
