Why Obsync

The privacy of self-hosted, with the ease of a single tap

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.

No cloud, no account

Your laptop and phone talk directly over your Wi-Fi or hotspot. There is no account to create and nothing to sign in to.

End-to-end encrypted

Every file is encrypted on the wire with X25519 key exchange and AES-256-GCM. Pairing is verified by fingerprint, not by trust.

AES-256X25519

Fingerprint pairing

Your phone announces itself with a fingerprint; the laptop shows it in settings and you tap approve. One approval and the devices are connected.

Conflicts, never lost notes

Edit the same note on both devices? Obsync flags the conflict and lets you choose — it never silently overwrites your work.

Snapshot versioning

Every edit is snapshotted on the server side. Roll a file back to any earlier version straight from the plugin settings.

One plugin, both devices

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.

How it works

From zero to synced in about a minute

No router config, no port forwarding, no terminal required. Both devices just need to reach each other on your network.

1

Install the Obsidian plugin

In Obsidian, open Settings → Community plugins and install Obsync from the catalog. It runs on both desktop and mobile — no separate apps.

2

Start the server on your laptop

Obsidian → Settings → Obsync → Start. On your phone, set the server URL (http://<laptop-ip>:42042) and press Sync now.

3

Approve your phone once

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.

Get it

Install from the Obsidian catalog

One plugin for every device — desktop and mobile. No APK, no installers, no terminal.

The plugin is the recommended path for most users. Prefer running your own daemon on a NAS or Raspberry Pi? The latest release also ships headless obsync-server-* binaries.
