Your Files, Everywhere, Private by Design
Fybrk syncs files in real-time across your devices with zero configuration. No cloud, no servers, just your devices talking directly to each other.
✅ What Actually Works
True 2-Way Sync
Changes on any device instantly appear on all connected devices. Create, modify, delete - everything syncs both ways.
Real-Time Detection
File changes detected instantly using fsnotify. Hash-based deduplication ensures only content changes sync.
SQLite Database
Tracks all file metadata locally with WAL mode for reliability. No cloud, no servers.
Internet Ready
Direct P2P connections with relay fallback. Works on local networks AND over the internet automatically.
Fully Tested
14 comprehensive tests covering all functionality. Integration tests verify end-to-end scenarios.
Zero Configuration
Just run `fybrk .` in any folder. No setup, no config files, no accounts needed.
