The best open source alternative to Syncthing is FreeFileSync. If that doesn't suit you, our users have ranked more than 100 alternatives to Syncthing and loads of them is open source so hopefully you can find a suitable replacement.

rsync is a pure command line client, requiring explicitly the command to be typed, with accurate data on the destination whereas Syncthing seems to run in background. This would require to use rsync plus something else (e.g. a scheduler, cron, acron, pick one)
I like rsync as an alternative to synthing because it can do pretty much the same. I like to use rsync for one off transfers or backups and syncthing for mirror syncronization.
they have some overlapping features but are pretty different tools. rsync is much more powerful in the diversity of things it can do and is purely command line. syncthing has a web interface (in addition to cli for those who are so inclined) and device apps and is simpler to set up. rsync will easily let you hose your files if you use it wrong whereas syncthing is more set up to avoid that.
Comprehensive file sync solution featuring individual sync settings per device and folder, Android-optimized interface, efficient battery-saving options, two-way SD card sync on Android 11+, and robust encrypted folder support for security.

Syncthing alone was not working for me to transfer files from work profile to personal profile so installed each syncthing and its fork and it worked.
Unison is a file-synchronization tool for POSIX-compliant systems (e.g. *BSD and GNU/Linux), macOS and Windows, with the caveat that the platform must be supported by OCaml. It allows two replicas of a collection of files and directories to be stored on different hosts (or diffe.

SyncTrayzor is a wrapper for Syncthing which allows Syncthing's window to be hidden in the tray area. SyncTrayzor has a built-in web browser to manage Syncthing without opening your browser. SyncTrayzor can be configured to automatically start at PC startup.
Ordinarily, SyncThing - which is great - runs in a web browser tab. Some people don't like that. Fair enough. So they made SyncTrayzor which gives you an alternative way of accessing SynThing functionality via the taskbar. It's not an alternative, though. It's an add-on. I don't see that much of an advantage, but others might.
This is an addon to Syncthing which enables to run Syncthing in the task bar.
It's an alternative way to use the front-end of syncthing (so it's not a full alternative to syncthing -- it is an add-on), and a great one. I recommend it to ease the usability curve for most users.

FreeFileSync is less prone to errors. I trust it more than Syncthing.
