Resilio Sync
What it is
Resilio Sync is a personal file synchronization and sharing product built around peer-to-peer technology. It can send files to multiple recipients without exposing a full folder or establishing a permanent sync connection. Advanced Folders let users assign ownership, change read and write permissions, and revoke access. Selective Sync creates searchable placeholder files so users can retrieve only the items they need, while bandwidth limits can be set for Sync activity. Resilio describes the product as cloudless: files remain on users’ devices, and a relay, if used, carries files encrypted without storing them. The company says Sync uses AES-128 encryption in transit and X.509 certificates for mutual authentication. Sync 3.0 is designated for personal, non-commercial use and requires a license to activate; it has no expiration date. Commercial users are directed to Sync v2 or Resilio business solutions. The listed platforms include Windows, macOS, Linux, iOS, Android, and NAS. A free plan is listed as free.
