As you may know, Syncthing is an open-source software that allows the users to easily synchronize files and directories between different computers in a secured and encrypted manner. The application has only a Web UI, so we need the browser to do our Syncthing tasks.

Yet another open-source software is Syncthing GTK, which is a GUI written in Python and GTK+3, adding an intuitive user interface to Syncthing, so that the users don’t need to use the browser anymore.
The latest version available is Syncthing GTK 0.7.4.1, which brings changes.
Supported Syncthing features:
- Everything what WebUI can display
- Adding / editing / deleting nodes
- Adding / editing / deleting repositories
- Restart / shutdown server
- Editing daemon settings
Additional features:
- First run wizard for initial configuration
- Running Syncthing daemon in background
- Half-automatic setup for new nodes and repositories
- Filesystem watching and instant synchronization using inotify
- Desktop notifications
