ByteSync

About

ByteSync is a free and open-source file comparison and synchronization tool designed for remote devices, transferring only differences with secure cloud orchestration. Launched as an alternative to established solutions like FreeFileSync, Syncthing, rsync, GoodSync, Duplicati, and SyncBack, it emphasizes privacy, decentralization, and a lightweight design, featuring no tracking and no registration requirements. Its comprehensive product portfolio includes core functionalities such as selective synchronization, AES encryption, a duplicate file finder, and large file transfer capabilities, with support for Rsync. Built using AvaloniaUI and Azure Functions, ByteSync is available across Mac, Windows, and Linux platforms. While generally well-received, user feedback notes occasional crashes when loading large directories like the C drive, a challenge handled by some competitors. As a free and open-source project, its financial model is not based on direct sales, and details regarding its leadership, founding history, or employee count are not publicly available.
