VaultSync for Obsidian

Self-Hosted Syncthing Notes

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Your Obsidian vault on your own server — private, offline-first, no third-party cloud. Now safer with multiple vaults and faster over local Wi-Fi. Your Obsidian vault, on your own server, synced to iPhone and iPad — peer-to-peer with Syncthing, no managed note cloud in the middle. VaultSync is the missing iOS bridge for people who already trust Syncthing with their notes. If your vault lives on your Mac, Linux box, NAS, or homeserver, VaultSync lets your iPhone and iPad join that setup — without moving anything into iCloud, Dropbox, or someone else's note-sync service. It syncs straight into Obsidian's iOS sandbox, so you open Obsidian and your vault is just there. WHY VAULTSYNC - Direct peer-to-peer sync between your devices and your own server. - Your Markdown never passes through our servers. We can't read, index, store, or proxy your notes — because they never reach us. - No account. No sign-up. No analytics SDK. No tracking. SET UP IN MINUTES - Pair with your desktop or server by scanning a Syncthing QR code (Device ID). - Pick the vaults you want on this device. - Open Obsidian — your notes are already in place. BUILT FOR REAL VAULTS - Markdown conflict resolver with side-by-side diffs, so you decide which version wins. - Sync activity timeline that shows what moved and when. - A "Sync Issues" panel with clear, actionable diagnostics instead of cryptic errors. - Quiet conflict notifications that update in place instead of spamming a new banner on every sync. HONEST ABOUT iOS SYNC iOS does not let third-party apps run a sync daemon in the background, and we won't pretend otherwise: - Server to iPhone/iPad: near-realtime incoming sync when the optional Cloud Relay delivers a silent push. - iPhone/iPad to server: most reliable when you open VaultSync. Background refresh can help opportunistically, but iOS decides when it runs. CLOUD RELAY (OPTIONAL) A small subscription (monthly or yearly) that sends a silent wake-up push the moment your server has changes, so incoming sync feels instant without opening the app. The relay only ever sees a wake-up signal — your Device ID, an APNs token, and a transaction ID. It never sees your note content, Markdown, filenames, folder names, vault structure, or any metadata. It needs a free Docker sidecar ("vaultsync-notify") on your server. VaultSync works fully without Cloud Relay — the relay only makes incoming sync faster. SUPPORT VAULTSYNC (OPTIONAL) Two one-time contributions — Small and Big — for people who want to support the project. They are a tip jar. They unlock nothing, and the app stays completely functional without them. REQUIREMENTS - iPhone or iPad on iOS/iPadOS 18 or later. - Syncthing already running on a Mac, Linux machine, NAS, or homeserver. - Obsidian installed on your device (for the vault to open into). PRIVACY & OPEN SOURCE VaultSync is peer-to-peer by design. There is no managed note cloud, no telemetry, and nothing to sign into. The app is open source under the MPL-2.0 license — read the code, build it yourself, or contribute. VaultSync is an independent project and is not affiliated with, endorsed by, or sponsored by Obsidian or Syncthing. "Obsidian" and "Syncthing" are trademarks of their respective owners.

  • This app hasn’t received enough ratings or reviews to display an overview.

Multiple vaults from one computer no longer get merged into one folder. FIXED • No more merged vaults — when one computer shared several vaults, the second could be pointed at the same local folder as the first, mixing their contents and pushing the mix back to every device. Each vault now always syncs into its own folder, and two vaults can never share one location. • Already-mixed setups are caught — if an earlier version had already merged two vaults, VaultSync now detects it on launch, pauses the affected vaults to stop further mixing, and shows you how to separate them. • Sync Filters: pasting a whole list works — the Add pattern field accepts multiple lines, so you can paste a list of filters and each line becomes its own entry. Blank lines and comments are skipped. • Your filter list keeps its order — removing or changing a filter no longer reshuffles the rest. IMPROVED • Faster, more reliable syncing on the same Wi-Fi — VaultSync now finds your other devices on the local network directly, instead of detouring through the internet.
