v2.1.0 · 12.4 MB
Open-source P2P file sync that's private, secure, and runs without a cloud.
Core Features
- Real-time bidirectional synchronization
- End-to-end encryption
- Peer-to-peer, no central server needed
- Web-based UI for easy management
- Cross-platform (Windows, macOS, Linux, etc.)
What It Can't Do
- •The web UI uses port 8384 by default — ensure firewall allows local access. 2. Device IDs are long strings; keep them private to prevent unauthorized pairing. 3. First sync of large data may use heavy bandwidth; set limits in settings. 4. Auto-upgrade is enabled by default; disable if needed. 5. Do not run multiple instances sharing the same data directory.
Use Cases
- Sync work files and code between two computers
- Backup photos and videos from phone to computer
- Self-hosted private sync alternative to iCloud/Dropbox
- Collaborative editing with version control
Syncthing is a continuous file synchronization program that syncs files between two or more computers in real time. It prioritizes data safety and security, encrypting all traffic end-to-end, and operates without a central cloud or server. Designed to be easy to use and fully automatic, Syncthing is ideal for individuals who want private, reliable synchronization across all their devices — including Windows, macOS, Linux, and even NAS systems. It is 100% open source under MPLv2, with no hidden fees or data collection. Unique strengths over proprietary alternatives include full transparency and no connection to third-party services, while being more lightweight than full-fledged cloud sync platforms like Nextcloud.
