How To Use It

QSyncthingTray does not come with Syncthing bundled. Therefore it needs to be downloaded from Syncthing. Once you specifiy the path to the 'syncthing' binary it will automatically spawn syncthing when you run QSyncthingTray.

To start Syncthing at boot (OS X):

  • Go to System Preferences and Users & Groups
  • Drag QSyncthingTray into the Login Items list


If you want to use HTTPS to connect to Syncthing on Windows, please download and install the OpenSSL DLLs. Then restart QSyncthingTray.

Build & Run

  • Get a recent version of Qt (5.5+)
  • QSyncthingTray can be either built with QWebEngine, QtWebView or native Browser support. By default it is built with QWebEngine. To enable QWebView pass -DQST_BUILD_WEBKIT=1 as an argument to cmake. For native browser support: -DQST_BUILD_NATIVEBROWSER=1.

Mac & Windows

  • Use either QtCreator or create an XCode or Visual Studio Project with CMake or QMake.
mkdir build && cd build  
cmake ../ -G Xcode


mkdir build && cd build
cmake .. && make
