SAI is a binary package bundler and application manager designed for Android and iOS. It functions as an installer and export tool that packages application source files and metadata into a proprietary format for portable distribution and backup.
The project features a rootless application deployment pipeline, allowing the installation of third-party packages on mobile devices without requiring system-level root access. It includes a split archive reconstructor to reassemble fragmented application files into complete installation directories during deployment.
The tool covers Android split APK installation and iOS application backup and distribution. It manages the export of application packages with embedded metadata and icons to track software origins.
