🔗 Multi-Device Synchronization
Fybrk supports secure peer-to-peer synchronization between devices.
Device Discovery
Devices automatically find each other on local networks
UPnP Port Forwarding
Automatic router configuration for external access
Secure Pairing
Encrypted handshake establishes trust
Smart Sync
Only newer versions and missing files transfer
🔒 Security First
Your Data Stays Private
- Local encryption: Files encrypted on your device before syncing
- You hold the keys: Encryption keys never leave your devices
- No backdoors: Even we can't access your files
- Open source: Security through transparency
Military-Grade Protection
- AES-256 encryption: Government-standard security
- Unique keys per file: Each file gets its own encryption
- Integrity checking: Detects tampering attempts
- Perfect forward secrecy: Past communications stay secure
⚡ Smart Synchronization
Only What Changed
Instead of uploading entire files every time, Fybrk:
- Breaks files into small chunks
- Only syncs the chunks that changed
- Saves bandwidth and time
- Works great even on slow connections
Conflict Resolution
When the same file changes on multiple devices:
- Fybrk detects the conflict automatically
- Keeps both versions so nothing is lost
- Lets you choose which version to keep
- Merges changes when possible
🌐 No Single Point of Failure
Distributed by Design
- No central servers: Devices talk directly to each other
- Works offline: Access files even without internet
- Peer-to-peer: Each device is equal in the network
- Resilient: If one device goes down, others keep working
Internet Connectivity Solutions
Fybrk ensures connectivity through multiple methods:
- Direct P2P: Local network connections (fastest)
- UPnP/NAT-PMP: Automatic port forwarding (80%+ router support)
- Relay servers: Fallback for guaranteed internet connectivity
- User configurable: Host your own relay servers
🕵️ Privacy Protection

Can you access my files?
No - we designed the system so that's impossible
What if Fybrk disappears?
Your files and keys stay with you - you're not locked in
How is this different?
We don't store your files, period. True peer-to-peer architecture.
