Obsidian Sync Pricing 2026: Is $4/Month Worth It?
Obsidian itself is free for personal use, but the moment you want your notes on more than one device, you hit the question every Obsidian user eventually asks: do I pay $4/month for Obsidian Sync, or do I roll my own sync for free? This breakdown covers exactly what you get, what you don’t, and when the official paid option actually makes sense in 2026.
Obsidian Sync pricing at a glance
| Plan | Price (billed annually) | Vaults | Storage |
|---|---|---|---|
| Free (local only) | $0 | Unlimited (one device) | Local disk |
| Obsidian Sync | $4/month | Unlimited synced vaults | 10 GB total, 5 MB/file history |
| Add-on storage | Available as upgrade | — | Up to higher tiers |
The headline number is simple: $4/month, billed annually (around $48/year). A monthly billing option costs a little more per month. That single subscription covers all your devices — desktop, laptop, iPhone, iPad, Android — with no per-device fees.
What $4/month actually buys you
Obsidian Sync isn’t just a file mirror. The paid features that justify the price for most people are:
- End-to-end encryption. Your notes are encrypted with a password only you hold. Obsidian’s servers never see your plaintext. For a notes app holding your second brain, this is the headline feature.
- Version history. Sync keeps up to one year of version history, so you can roll back a note (or recover a deleted one) without a separate backup system.
- Selective sync. Choose which vaults and even which file types sync — handy if you keep large PDFs or images out of the synced set.
- Cross-platform reliability. Conflicts are handled gracefully, which is the single biggest pain point of DIY sync setups.
The free alternatives — and their real cost
You can absolutely sync Obsidian for $0. The two common routes:
- iCloud / Google Drive / Dropbox. Drop your vault in a synced folder. Works, but you’ll occasionally fight sync conflicts, and there’s no encryption layer beyond whatever the cloud provider gives you. Mobile reliability is the weak spot.
- Git. Power users version their vault with Git. It’s free and bulletproof for version history, but it requires manual commits/pulls (or plugins) and is overkill for non-technical users.
The honest math: the “free” options cost you time and reliability, not money. If your notes are casual, free sync is fine. If your vault is your work, $48/year to never think about sync conflicts or encryption again is cheap.
Who should pay for Obsidian Sync
Pay for it if:
- You use Obsidian on mobile + desktop daily and need rock-solid reliability.
- You want end-to-end encryption for sensitive notes.
- You don’t want to maintain a Git or cloud-folder workaround.
Skip it if:
- You only use one device.
- You’re comfortable with Git or a cloud folder and your notes aren’t sensitive.
- You’re still evaluating whether Obsidian is your long-term home.
How it compares to other PKM sync costs
Obsidian’s $4/month sits at the low end of the PKM market. Logseq Sync runs about $5/month, while Notion bakes sync into its $10/month Plus plan (you can’t separate it out). Roam Research has no free tier at all — it’s $15/month minimum. Seen against that field, paying only for sync on top of a free, local-first app is one of the better-value setups in note-taking.

The bottom line
Obsidian Sync at $4/month is a fair, honest price for encrypted, reliable, cross-device sync of a free app. It’s not mandatory — DIY sync works — but for anyone whose notes are mission-critical, it removes the single most annoying failure mode in the Obsidian workflow. If you’re on the fence, the deciding factor is encryption: no free option matches it.
