byosynch

A file sync client that keeps a chosen folder synchronized across devices using user-controlled SSH storage, solving the need to sync files without relying on vendor-owned storage or routing files through intermediary servers. It sells to developers, IT professionals, and individual consumers who use Mac and Linux (with iOS read access) and want to manage their own storage provider such as rsync.net or a self-run server. It is positioned as a bring-your-own-storage alternative where SSH private keys stay on devices and files travel directly to storage, with servers handling only accounts and licensing.
