Why people self-host Syncthing

Syncthing removes the central server from file sync. Devices exchange data directly, which is excellent for personal machines, laptops, phones, and local-first workflows.

The tradeoff is that sharing, web collaboration, and server-side permissions are intentionally limited. Document device IDs, folder paths, ignore patterns, and conflict handling.

Deployment notes

Syncthing is listed with support signals for linux, windows, macos, android. Check the upstream documentation before exposing it to the internet, review authentication defaults, and keep backups outside the primary host.
