Impactor
Impactor is a sideloading utility for iOS and tvOS that allows developers and advanced users to install custom applications directly onto their Apple devices without going through the App Store. It was originally developed by Saurik and became widely used by the jailbreaking and iOS development community. The app is primarily used by developers testing beta builds, security researchers, and users seeking to install unsigned or modified applications on their devices.

1 suggestionGood news: A native Apple Silicon version of Impactor is now available. The app has been forked and is actively maintained by the community at khcrysalis/Impactor. Version 2.3.0 and later ship as a universal macOS build (supporting both Intel and Apple Silicon). You can download the latest native version directly from the project's GitHub releases page. This is a maintained fork that continues development where the original project stalled, so you should be able to upgrade and continue using it on Apple Silicon without any compatibility issues.
