claration/impactor

Impactor is a cross-platform iOS sideloading application that enables users to install apps on iOS, iPadOS, and tvOS devices without enrolling in Apple's developer program.

The tool solves the problem of installing unsigned applications on Apple devices by replicating Xcode's certificate and provisioning profile workflow. It uses your Apple ID to request the necessary credentials from Apple, then signs and installs applications locally. The approach works on macOS, Linux, and Windows, though each platform has specific requirements: Linux needs usbmuxd installed, and Windows requires iTunes for device drivers. The tool supports installing helper applications like SideStore and LiveContainer, which enable app refreshing and persistence beyond the standard seven-day free developer certificate limit.

Impactor suits developers and power users who want to sideload applications without purchasing an Apple developer account. It is particularly useful for those testing apps across multiple devices or working with tweaks and custom frameworks. The tool distinguishes itself by supporting advanced features like tweak injection via ElleKit, the ability to inject .deb and .dylib files, and support for .framework, .bundle, and .appex directories. It also handles entitlement registration for specialized use cases like emulators. Unlike some alternatives, it provides proper support for SideStore and LiveContainer integration, generates P12 certificates for use with other tools, and automatically manages pairing files for device trust.

The project maintains active development with regular updates addressing platform-specific issues and feature improvements. Work spans multiple operating systems with particular attention to Linux compatibility challenges around device detection and usbmuxd behavior. The codebase shows ongoing refinement of entitlement handling and device utility features, alongside continued expansion of supported injection and framework types.
