ByteSync

ByteSync is a free and open-source application designed for efficient file comparison and synchronization across remote devices.

Instead of copying entire files, ByteSync detects and transfers only the differences, saving time and bandwidth. It works on-demand and supports Windows, macOS, and Linux.

With built-in end-to-end encryption and a simple cloud orchestration system, ByteSync eliminates the need for VPNs or firewall configurations.

ByteSync is optimized to handle both very large files and large sets of small files, making it ideal for synchronizing heavy datasets as well as codebases or project folders with thousands of items.

Whether you're backing up projects, syncing devices across locations, or managing file transfers remotely, ByteSync makes the process simple, fast, and secure.
