Zettlab Sync

Zettlab Sync is a WebDAV-only Obsidian plugin for syncing a vault with Zettlab Memo.

It deliberately keeps Markdown plaintext on Memo so Zettlab can index and use the notes. It does not include cloud providers, OAuth, QR pairing, a paid tier, or end-to-end encryption.

What it does

• WebDAV Basic or Digest authentication
• Manual sync, periodic sync, and optional sync after a note is saved
• Connection test that creates and removes a temporary remote file
• Basic conflict choices: keep newer or keep larger
• File-size and path-pattern exclusions

Local development

npm install
npm test
npm run build

The build creates main.js. To test it in a disposable vault, copy main.js, manifest.json, and styles.css into:

<vault>/.obsidian/plugins/zettlab-sync/

Then enable Zettlab Sync in Obsidian community plugins, set the WebDAV address and credentials, click Test, and use Sync now with a disposable note first.

Safety

• Back up a vault before first sync.
• WebDAV credentials are stored in Obsidian's local plugin data. Do not commit or share that file.
• Automatic sync only runs while Obsidian is open.

Privacy and network use

• The plugin reads and writes files in the current Obsidian vault to synchronize them with the configured WebDAV service.
• It only contacts WebDAV addresses configured manually or supplied by Zettlab Memo during one-click setup. Managed setup accepts private-network Memo addresses and HTTPS addresses under zettlab.com.
• WebDAV credentials and endpoint settings are stored locally in this vault's Obsidian plugin data.
• The plugin contains no telemetry, advertising, or third-party analytics. One-click setup requires Zettlab Memo; manual WebDAV configuration remains available.
• Files are synchronized as plaintext. Use HTTPS for public endpoints and back up the vault before the first sync.
