Pros and cons

+ what works
  • +No central server, so there is no cloud copy to leak or seize
  • +MPL-2.0, written in Go, with reproducible builds and an active foundation
  • +Works on Linux, macOS, Windows, BSDs, and as a daemon on most NAS boxes
  • +Versioning, selective sync, and send-only or receive-only folders are built in
watch out for
  • All devices that hold a copy must be online together for changes to propagate
  • No official iOS client; the actively maintained option is the paid third-party Möbius Sync
  • The official Android wrapper was discontinued in 2024; users migrate to Syncthing-Fork via F-Droid
  • No built-in web file browser or sharing links; it syncs folders, it is not a Drive replacement

Privacy notes

Syncthing connects your devices directly over TLS with per-device certificate pinning; there is no vendor account, no cloud storage, and no third party holding your files. Public discovery and relay servers run by the project help devices find each other and traverse NAT, but they only see encrypted traffic and device IDs, not file contents. The Syncthing Foundation, a Swedish non-profit, runs that infrastructure and the build pipeline.
