Send files and folders between nearby phones and computers over your local network.
Replace uploading files to Dropbox merely to move them between nearby devices. This covers manual same-network transfers only; it does not replace paid cloud capacity, remote sharing, backup or sync. Dropbox already has a free plan, so no claim is made that basic transfers require payment.
Both devices need LocalSend and a reachable local network; firewalls or network isolation can block discovery. No remote links, continuous cloud sync, offsite backup or Dropbox version history. A firsthand report describes missed subfolders during folder drag-and-drop: check received folders before deleting originals. Capacity and speed depend on your devices and network.
Each comparison covers the workflow described above, rather than every paid feature.
