Syncthing

Aplicación Descentralizada

A continuous file synchronisation program that keeps folders identical across two or more computers in real time, directly between devices and with no central server. Devices are identified by a cryptographic certificate fingerprint (the Device ID); only devices a user has explicitly accepted can connect, and all traffic is encrypted with TLS including forward secrecy. Devices find each other on the local network or, optionally, through global discovery servers, and can fall back to community relay servers when no direct connection is possible. The protocol is a documented specification, the code is open source and development is public. It is maintained under the Syncthing Foundation, a registered Swedish non-profit foundation .
