ownCloud vs Resilio Sync

ownCloud is open-source file sync, sharing, and content-collaboration software for teams working across devices and locations. Teams can share internally or externally, invite guests, create file drop folders, comment, and collaborate in real time. It supports Windows, macOS, Linux, iOS, Android, and web access, with file versioning, zero-knowledge encryption, and business administration controls. Deployment options include on-premises, a cloud of choice, or ownCloud.online, hosted on servers in Germany. External storage can bring services such as S3, Dropbox, and SharePoint into a single access point. Microsoft integrations include Office Online Server, Office 365, and Microsoft Teams; Collabora Online supports collaborative browser-based editing of documents, spreadsheets, presentations, and diagrams, with live changes and revision history. The ownCloud.online plans list 256-bit AES and SSL/TLS encryption, multi-factor authentication, end-to-end encryption, and a File Firewall. The Community plan supports unlimited users; Standard and Enterprise start at 25 users. Hosted options cover one to four users with 500GB, or start at five users with 1,000GB and 200GB extra storage per additional user.

Resilio Sync is a personal file synchronization and sharing product that uses peer-to-peer technology. It can send files to multiple recipients without exposing an entire 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 placeholders so users can download chosen files, and bandwidth limits can be set for Sync activity. Resilio describes the product as cloudless: files remain on users’ devices, while relays, if used, carry encrypted files without storing them. The maker says Sync uses AES-128 encryption in transit and X.509 certificates for mutual authentication. The listed platforms are Windows, macOS, Linux, iOS, Android, and NAS. Sync 3.0 is for personal, non-commercial use and requires a license to activate; commercial users are directed to Sync v2 or Resilio business solutions. The free plan has no expiration date.
