What is Syncthing?
Syncthing synchronises files between multiple devices in real time, without routing data through external servers or cloud services. Devices connect directly via peer-to-peer. Anyone who sets up Syncthing retains full control over their data. There is no provider to trust, no account to create and no monthly costs. The project is fully open source and under active development.
Core features
- Decentralised P2P synchronisation between any number of devices without a central server
- Encrypted transfer of all data between participating devices
- NAT traversal and firewall support with automatic configuration, so Syncthing works in typical home network and office environments
- Web interface for managing folder shares, devices and synchronisation status
- Cross-platform support on Linux, macOS, Windows and Android
- File versioning to restore earlier versions of files
Who is Syncthing for?
Developers who want to sync project files between multiple machines without repurposing a cloud repository benefit directly from the P2P approach. Teams working with sensitive data who do not want a cloud provider in the process chain will find a technically clean solution here.
Anyone who has never worked with self-hosted services should expect a short learning curve. The concepts behind device IDs, folder shares and connecting via relay servers are not self-explanatory. Those familiar with the command line and configuration files will generally have Syncthing running quickly.
Context & alternatives
Syncthing belongs in the category of self-hosted synchronisation solutions. Unlike services such as Dropbox or Google Drive, no third-party infrastructure runs in the background. The comparison with Nextcloud is obvious: Nextcloud offers more features and a more sophisticated collaboration environment, but requires a dedicated server. Syncthing does not. Anyone who only wants to sync files and does not want to run a server should choose Syncthing. Those who additionally need calendars, contacts or document editing will want a more comprehensive self-hosted platform.
