Hey Product Hunt 👋 I built VaultSync because I had one annoying gap in my personal knowledge setup. My Obsidian vault lived on my own devices. I already used Syncthing on my Mac and server. But iPhone/iPad sync was always awkward: iCloud was not the setup I wanted, and I did not want to move my notes into another managed sync cloud. VaultSync is my attempt to solve that cleanly. It syncs Obsidian vaults directly into Obsidian’s iOS sandbox using Syncthing. You pair your existing Syncthing device via QR code, select your vault, and open Obsidian once the files are synced. A few things I care about: - no account - no analytics - no tracking - open source under MPL-2.0 - no note content passing through my servers - honest handling of iOS background limitations That last point matters: iOS does not allow third-party apps to run an always-on sync daemon. So VaultSync is not promising magic. Server-to-iPhone sync can be near-realtime with the optional Cloud Relay. iPhone-to-server sync is most reliable when VaultSync is opened. I’d love feedback from Obsidian users, Syncthing users, and self-hosters.
