## Kitsmith's take

A fundamentally different model from Dropbox-style sync: Syncthing connects your devices directly over an encrypted, authenticated connection and keeps folders in sync between them, with no company-run server in the middle and no account to create. That means no cloud storage tier to buy, but also no web access to your files from a browser — it only syncs between devices you control. Development is stewarded by the nonprofit Syncthing Foundation, with commercial support and engineering resources sponsored by Kastelo Inc. The project has shipped continuously since its 2013 release and is entirely open source on GitHub.
