Resilio Sync

Although not touted by the developers as an intended direct replacement nor competitor to cloud-based file synchronization services, it has attained much of its publicity in this potential role.

[3] On 24 January 2013, BitTorrent, Inc. announced a call for pre-alpha testers to help test a new "distributed syncing product to help manage personal files between multiple computers".

[4] Several private pre-alpha builds of "SyncApp" were subsequently made available to a limited group of alpha testers between January 2013 and April 2013.

[8] On 17 July 2013, BitTorrent Sync migrated from "alpha" to "beta", released an Android app, and introduced versioning.

[13] On 9 September 2015, with the release of Sync 2.2, in the free version, the 10 folder limit that had been introduced in 2.0 was removed.
