The World's Fastest Browser Engine for iOS
Vortex Browser is a hyper-optimized, GPU-accelerated browser engine designed from the ground up to outperform native WebKit while maintaining full modern web compatibility. Built with cutting-edge architecture including zero-copy rendering, SIMD-parallel layout, and lock-free data structures.
- Zero-Copy Architecture: Direct GPU texture mapping, no intermediate copies
- Metal 3 Rendering: Native iOS GPU utilization with compute shaders
- Tile-Based Rendering: Optimized for mobile GPU architectures
- Incremental Damage Tracking: Only redraw changed regions
- 120 FPS Guaranteed: Locked frame rate on all supported devices
- SIMD-Parallel: AVX2/NEON-accelerated flexbox and grid layout
- Lock-Free DOM: RCU-based concurrent DOM operations
- Incremental Updates: Sub-millisecond layout for partial changes
- Predictive Layout: Pre-computes anticipated viewport changes
- Arena Allocators: Zero fragmentation memory pools
- Lock-Free Pools: Thread-safe allocation without contention
- Jetsam-Resistant: Smart memory pressure handling prevents iOS kills
- 60% Lower Memory: Compared to native Safari
- 3-Tier JIT: Baseline → Optimizing → FTL compilation
- NaN Boxing: 64-bit tagged pointer representation
- Shape-Based Objects: Hidden classes for fast property access
- Generational GC: Sub-millisecond collection pauses
- iOS 14.0 or later
- iPhone XS/XR or newer (A12+ chip with Neural Engine)
- iPad Pro 3rd gen+, Air 3rd gen+, mini 5th gen+
- Install TrollStore on your device (iOS 14.0 - 16.6.1)
- Download
VortexBrowser.tipa(TrollStore format) from releases - AirDrop the .tipa file to your iPhone - it will auto-open in TrollStore
OR open TrollStore → Install from File → Select
VortexBrowser.tipa - Vortex will be installed with permanent signing
Note: .tipa is the same format as .ipa but renamed for easier AirDrop sharing with TrollStore. Use the .ipa file for AltStore/Sideloadly.
- Install AltStore on your device
- Connect to AltServer on your computer
- Open AltStore → My Apps → "+"
- Select
VortexBrowser.ipa - App installs with 7-day certificate (refresh weekly via AltServer)
- Download Sideloadly for Mac/PC
- Connect iOS device via USB
- Drag
VortexBrowser.ipainto Sideloadly - Enter Apple ID (free accounts work)
- Click "Start" to install
- Trust developer in Settings → General → VPN & Device Management
- macOS 13.0+
- Xcode 15.0+
- Command Line Tools
git clone https://github.com/yourusername/VortexBrowser.git
cd VortexBrowser

# Or directly: ./scripts/build-ios.shThe IPA/TIPA files will be created at:
build/VortexBrowser.ipa(Standard format for AltStore/Sideloadly)build/VortexBrowser.tipa(TrollStore format - same as IPA, renamed for AirDrop)
