Our verdict: Resilio Sync does the same job as Syncthing with a friendlier desktop app: folders sync directly between your devices, with no cloud and no size limits. Since the former Pro features became free, selective sync and folder permissions cost nothing. It is closed source, so you have to trust the vendor's code.
About Resilio Sync
Resilio Sync transfers files between your computers, phones and NAS devices using peer-to-peer technology, without storing them on a cloud server. You share a folder by sending a link or key, and every device with access syncs it. Bandwidth limits let you keep large transfers from saturating your connection.
Resilio now ships all features of the former paid Sync Pro plan in the free download. That includes Selective Sync, which shows placeholder files and downloads them only when needed, and Advanced Folders, which let you change ownership and read or write permissions at any time. Resilio's paid products are aimed at businesses rather than home users.
