About Resilio Sync

Resilio Sync (formerly BitTorrent Sync) is a file synchronization tool that moves data directly between devices using peer-to-peer technology. It does not rely on cloud storage or a central server, which makes it useful for large files, offline networks, or users who want full control over their data. You can sync folders across computers, NAS devices, mobile phones, and even remote servers.

The software supports selective sync, encrypted keys for sharing, and one-way or two-way syncing. It runs on Windows, macOS, Linux, iOS, Android, and most NAS platforms like QNAP and Synology. The core technology is based on the BitTorrent protocol, adapted for file replication. Version history is limited but available in paid tiers.

Resilio Sync is best for teams and individuals who need fast, serverless file distribution across multiple locations. The home version is free for personal use. Business and server editions are paid, with centralized management and LDAP integration. Resilio Inc. is based in San Francisco.
