Local-first — your vault stays on disk
Your notes never touch a server
MIT OR Apache-2.0, your choice
Obsidian Sync costs $4 a month and routes your notes through a third-party cloud. Obsync does the job between your own devices — encrypted, automatic, and free.
Your laptop and phone talk directly over your Wi-Fi or hotspot. There is no account to create and nothing to sign in to.
Every file is encrypted on the wire with X25519 key exchange and AES-256-GCM. Pairing is verified by fingerprint, not by trust.
Your phone announces itself with a fingerprint; the laptop shows it in settings and you tap approve. One approval and the devices are connected.
Edit the same note on both devices? Obsync flags the conflict and lets you choose — it never silently overwrites your work.
Every edit is snapshotted on the server side. Roll a file back to any earlier version straight from the plugin settings.
The same plugin runs on desktop and mobile. Start the server on your laptop, sync from your phone, and manage devices in the settings tab.
No router config, no port forwarding, no terminal required. Both devices just need to reach each other on your network.
In Obsidian, open Settings → Community plugins and install Obsync from the catalog. It runs on both desktop and mobile — no separate apps.
Obsidian → Settings → Obsync → Start. On your phone, set the server URL (http://<laptop-ip>:42042) and press Sync now.
The laptop shows your phone's fingerprint — tap approve. From then on, both sides stay in sync. Files edited on both sides are surfaced as conflicts, never silently overwritten.
One plugin for every device — desktop and mobile. No APK, no installers, no terminal.
