What is Syncthing?
Syncthing is a continuous file synchronisation program that keeps files in sync between two or more computers in real time. Its site states that none of your data is stored anywhere except on your own computers, that there is no central server, and that all communication is secured with TLS.
The source code is available on GitHub under the Mozilla Public License 2.0. Because data stays on your own devices, there is no hosted storage to fall back on; consider how you will back up, share and recover files. Pricing is not stated on the reviewed page.
