Free alternatives to Resilio Sync
1 free program that can replace Resilio Sync, a pairing checked by Radar's AI reviewer or by Radar.
Resilio Sync keeps folders in step between computers, phones and servers by sending files directly from device to device instead of storing them in a company cloud. People use it to back up photos, share large folders with colleagues, or mirror files between a laptop, a home server and a phone. It is a commercial product, and some features depend on the plan.
Before switching, list what you sync and how. Check that the new tool runs on every device you use, including your phone and any NAS or server, and learn how devices are paired and how folders are shared. Syncing directly between devices usually needs at least one of them online, so think about which machine stays on. Compare how conflicts, deleted files, selective sync and very large files are handled, and test with a copy of a real folder before pointing the tool at your only copy. If other people receive your files through Resilio links or keys, they will need to install and pair with the new tool too. Syncing is not a backup, so keep a separate copy.
Syncthing is the option listed below, and a spare folder is a good place to try it first.
