Apps: Syncthing
Last updated: September 17, 2025
What Syncthing synchronizes files directly between your devices without a central server. Android clients are FOSS.
Why on Zer0
- Peer-to-peer, encrypted; no third-party cloud required.
- Ideal for secure local backups and password database sync.
Safe use
- Share folders only with trusted device IDs; verify fingerprints.
- Use versioning for critical folders; restrict background sync on metered data.
- Pair with KeePassDX for database sync; follow compartment rules.
Limits
- Discovery/firewall/NAT can complicate connectivity.
- Continuous sync may impact battery if misconfigured.
