| DataFoundry | React · FastAPI · PostgreSQL | CSV upload, validation and analytics |
A patch manager for rooted Android devices. It uses LSPosed / libxposed (API 101) to apply bytecode patches to other apps as they start. The target APK is not modified on disk, so it keeps its original signature and Play Protect status.
- Patches ship as signed
.nxbbundles loaded into process memory, not installed as apps. They come from Nexfusion-Patches. - Obfuscated class and method names are resolved at runtime with DexKit, using bytecode opcode patterns and string fingerprints. Fixed offsets would break on the next app update; pattern matching usually does not.
- Each hook runs inside error handling, so a patch that fails to resolve leaves that one feature off instead of crashing the host app.
- Banking, payment and security-critical apps are excluded from patching.
Supported targets include YouTube, Reddit, Instagram, Facebook, Telegram, X and Maps. Requires Android 8.1+ (API 27) and root.
