How much RAM does Obsidian LiveSync (CouchDB) need?

Plan on 1–2 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Obsidian LiveSync (CouchDB) plus your other workloads fit in RAM with room to spare.

Productivity

Sync your Obsidian vault through your own server.

Run a CouchDB backend so your Obsidian notes sync securely between devices without going through a third-party service.

If you write in Obsidian and care where your notes live and sync, a self-hosted LiveSync backend keeps them on your own box.
