Daily cross-device file transfer often relies on cloud storage, which has limitations (space/speed) and privacy leak risks—quite a hassle.
Today we recommend FileSync, a free open-source tool solving these issues. With end-to-end encryption and real-time transfer, it’s a safer, more efficient cross-device solution.
1. Core Advantages: Security & Speed Combined
FileSync uses WebRTC-based peer-to-peer (P2P) transfer—files move directly between devices, no intermediate servers. Key benefits:
- Fast speeds: No server relaying boosts efficiency, especially for large files.
- Strong privacy: End-to-end encryption lets only sender/receiver access content, avoiding third-party interception.
2. Practical Features: For Multiple Scenarios
FileSync includes useful features for diverse needs:
- Multi-device transfer: Supports one-to-many distribution (great for teams/families).
- No installation: Clean web interface—use via browser, low entry barrier.
- Easy self-hosting: One-click Docker deployment + auto-HTTPS; build private services easily.
- Extra security: Set access passwords; QR code sharing for quick recipient access.
3. Get & Deploy: Open-Source & User-Friendly
As fully open-source software, FileSync’s code is on GitHub:
For quick setup, use Docker—few steps to build your own service, fit for personal or small-team use.
