Kryptix is a modern, high-speed file sharing and messaging application designed to work both locally and universally.
Unlike typical local send apps, Kryptix is:
- ⚡ Faster: Multi-threaded parallel chunking pushes your network limits.
- 🌐 Universal: Works across any network (not limited to local LANs).
- 🔒 Secure: True End-to-End Encryption (AES-256-GCM) ensures your data is safe.
- 🧠 Smart: Automatically falls back to open relay servers if direct connections fail.
💡 Built as a solo project in just 1 week by a passionate developer!
- 🚀 High-speed file transfer with zero-bottleneck architecture
- 🌍 Cross-network communication using standard STUN/TURN technologies
- 🔐 Secure messaging system that operates concurrently with file drops
- 📡 Multiple server support (Relay and OpenRelay ready)
- 💻 Cross-Platform: Works on Web, Mobile (Capacitor), and Desktop (Electron)
