* Live Showcase & APK: https://djsusmith.github.io/hyperstream-android/

* License: GPL-3.0 (100% Free & Open Source, 0 ads, 0 telemetry)

Tech Stack

* Core Engine: Written in Rust using `tokio`, custom work-stealing segment halving down to 12 KB chunks, and `librqbit` for embedded BitTorrent swarm handling.

* Frontend: Kotlin & Jetpack Compose (Modern Obsidian dark theme, reactive telemetry, Material 3).

* Bridge: Zero-copy JNI / C FFI Native Bridge (`libmdm_android.so`).

Key Features

⚡ Up to 128 Parallel Connections:* Real-time socket shedding and dynamic connection pooling that easily saturates high-speed 5G and Wi-Fi 7 connections.

🧲 Native BitTorrent Swarm:* Magnet links, torrent files, sequential downloading (stream while downloading), DHT, and PEX without any third-party daemon.

🎬 Built-in Media Grabber:* Direct 4K YouTube stream extraction and watermark-free video sniffer with multi-stream audio/video muxing.

🔋 Android Background Resiliency:* Foreground service with partial WakeLock and High-Performance Wi-Fi Lock to prevent system Doze throttling.

📂 Safe File Management:* Integrated Android `FileProvider` with 1-tap open and double-confirmation deletion protection.

Context & Why I Built This

Most existing Android download managers are either abandoned or filled with intrusive full-screen ads, tracking SDKs, and paywalled thread limits. I wanted a clean, blazing-fast, genuinely open-source alternative that runs natively on ARM64 without GC pause jitter.

The project is actively maintained (currently on v0.6.0). I’d love to hear your thoughts, feedback, bug reports, or feature requests! PRs and stars are always welcome.
