Dropbox pioneered the synced folder that follows you across devices and can be shared by link. Running your own sync server avoids the storage-tier pricing, lets files live on hardware you control, and means shared links and file history are not governed by someone else's terms.
9 open-source alternatives to Dropbox you can host yourself, ranked by GitHub stars and updated daily.
