Synology
from your desktop
Browse your Synology NAS via File Station API — no extra packages to install on DSM. Dual-pane copy to S3, SFTP, Google Drive, or local storage.
DSM File Station is browser-only for serious file work
Synology's File Station works in a browser tab — but bulk renames, cross-NAS copies, NAS → S3 backups, and side-by-side folder comparison need a desktop client. Synology Drive sync mirrors one folder; it won't open your NAS next to an S3 bucket. A synology file manager should use File Station API out of the box on any DSM 6.2+ NAS, with a transfer queue and automation for offsite backups without extra packages.
File Station API — built into every Synology NAS
CloudPairs connects with hostname/IP, port (5000 HTTP / 5001 HTTPS), username, and password on Windows 10/11 or macOS 13+. Uses Synology File Station API — enabled by default, no package install required. Browse shared folders visually, queue transfers, and automate NAS → cloud backups. Credentials encrypted in your OS keychain. Free 14-day Pro trial, no credit card, then $12/mo for automation and unlimited connections.

CloudPairs vs alternatives
| Alternative | Limitation |
|---|---|
| DSM File Station (browser) | Tab-only UX — no dual-pane, no cloud transfer queue, weak bulk operations. |
| Synology Drive sync | Single-folder mirror — not a multi-cloud browser with S3/SFTP panes. |
| SMB mount in Explorer | No S3 pane, weak queue UX, permission and disconnect quirks on macOS. |
