What is it?

Feather is an iOS and iPadOS application manager that signs and installs IPA files directly on the device, using certificates from the Apple Developer Program. It is meant for sideloading apps outside the App Store and is written in Swift.

Besides signing and installing apps, Feather lets users view details about installed apps and their certificates, and it can add AltStore-compatible source repositories. Signing options cover modifying an app's appearance, enabling Files app support, and patching apps for compatibility, including Liquid Glass. Advanced users can inject .deb and .dylib tweaks through Ellekit.

The project states it does not include tracking or analytics and is distributed under the GPL-3.0 license.
