What is SyncThingy?
SyncThingy is a small C++ application that sits in your system tray and gives you a quick way to see whether Syncthing is running and to start or stop it. It was created by developer zocker_160 and first appeared in 2021, building on the mature Syncthing core that has been in active development for over a decade. The tool is packaged for the major Linux distributions and is distributed through Flathub.
The target users are people who already use Syncthing for file sync but want a more convenient way to control it without opening a browser. It is ideal for those who prefer a minimalistic interface and want to avoid the overhead of a full‑featured sync client.
Compared to Windows tools like OneDrive, SyncThingy feels more hands‑on. Instead of a cloud‑centric service that manages credentials and sync automatically, you manually configure folders in Syncthing and then use SyncThingy to toggle the daemon. The experience is more transparent and gives you direct control over the sync process.
Best for: Users who want a quick, low‑overhead way to manage Syncthing on Linux.

How to install SyncThingy on Linux
flatpak install flathub com.github.zocker_160.SyncThingysudo apt install syncthingsudo apt install syncthingsudo dnf install syncthingsudo pacman -S syncthing-relaysrvsudo zypper install syncthingTips for Windows users
If you’re coming from OneDrive, note that Syncthing does not use a central cloud; you set up shared folders on your own devices. SyncThingy only controls the Syncthing daemon, so you still need to configure folder paths and device connections in the Syncthing web UI. Keyboard shortcuts are not built into SyncThingy; you’ll rely on the tray icon or the web interface for advanced options. File formats are standard OS files – no special conversion is required.
