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.
