A Revolutionary, Lightweight, and Zero-Footprint Dynamic Application Runner for Android & Beyond.
Multi Box is a next-generation application environment that breaks traditional Android constraints. It allows users to run modular, standalone applications packed inside a custom .hpk (Hybrid Package) format.
With Backward & Forward Compatibility (supporting Android 5.0 Lollipop up to Android 14+ / API 34+), Multi Box bypasses strict system limitations like Scoped Storage and Package Visibility Rules through runtime isolation and efficient application bridging.
Multi Box is engineered to handle three distinct types of applications within a single client, giving developers unmatched flexibility:
| App Type | Description | Core Engine |
|---|---|---|
| 🌐 URL Base | Directly wraps any web application or portal into a native-feeling application experience. | Optimized WebView |
| 💻 HTML/Script Base | Runs local HTML, CSS, JavaScript, or lightweight scripts locally with full GUI integration. | Local Sandbox Engine |
| ⚡ Dex Base | Loads and executes compiled Android .dex (Dalvik/ART executable) files dynamically at runtime. |
Advanced DexClassLoader |
- True Native Feel: Installing, running, or uninstalling an
.hpkfile gives the exact same premium user experience as standard Android.apkfiles. - Zero Footprint & High Security: To ensure absolute privacy and storage efficiency, all unpacked execution files are automatically wiped out immediately upon application exit (
OnStroke/OnExit). - Cross-Platform Vision: Built with a clean architectural layout, meaning the same
.hpkpackage (URL & HTML base) can effortlessly run on a Windows Host application in the future with zero code modification. - Full Modern Android Support: Seamlessly handles Android 11 to 14+ security restrictions, including dynamic read-only memory alignment for dynamic class loading.
This repository acts as the central hub for the entire .hpk ecosystem:
/multi-box-engine/-> The core Android runtime client application (releases available)./hpk-builder/-> The official compiler/toolchain used to bundle your websites, scripts, or dex files into.hpkpackages./sample-hpk-apps/-> A collection of lightweight, ready-to-run child.hpkapplications for testing.
We provide a specialized, lightweight compiler called HPK Builder. You can use it to package your projects:
- Open HPK Builder.
- Select your project source (Website URL, Local HTML/Script folder, or Compiled
.dex). - Set your Application ID and Metadata.
- Click Compile to generate your standalone
.hpkfile. - Transfer it to your device and open it via Multi Box!
We are actively refining individual data sandboxing for URL and HTML-based applications to separate cache, cookies, and LocalStorage directories per .hpk app, ensuring total isolation from the host APK.
This project is currently open-source! We welcome developers to test, create innovative .hpk child apps, and contribute to the engine.
