Syncthing
Syncthing is a native macOS file synchronization app that keeps folders in sync directly between your devices without using a central cloud service.
What is Syncthing?
Syncthing is a native macOS file synchronization app for keeping folders in sync across your own devices. It is designed for people who want direct device-to-device syncing for documents, projects, notes, and other files without relying on a central cloud storage provider. On Mac, the app bundles and manages a local Syncthing instance and gives users a menu bar style interface for monitoring status, opening the web interface, and adjusting common settings. It works well for personal backups, multi-computer workflows, and self-managed file sharing between trusted devices. Advanced users can also point the app at a local Syncthing instance for specialized setups. The macOS app is maintained under the Syncthing project and provides a more convenient desktop experience for running Syncthing on a Mac.

Safety overview
Status: Mostly safe
Syncthing is legitimate synchronization software, and background network activity is normal because its job is to keep selected folders updated between devices. It may need access to folders you choose to sync, and removing the app can stop automatic synchronization on that Mac while leaving synced files in place. Because it can continuously exchange files with other devices you have linked, use it only with devices and folders you trust and review your shared-folder settings before syncing sensitive data.
Recommendation: Keep Syncthing if you use it to sync files between your devices or maintain a self-managed backup workflow. If you no longer use it, you can remove the app, but expect syncing on that Mac to stop until you install and configure it again. Before removing it, make sure any important files have finished syncing to your other devices.
