Obsidian Sync Alternative: A Local-First Approach

The most-recommended Obsidian Sync alternative is not another sync service — it is needing less sync. Obsidian Sync costs $4 per user per month billed annually, which totals $48 a year, or $5 billed monthly.¹ A local-first note app keeps every note on your own device and works fully offline, so the subscription answers a problem you may not have.

The honest version of this comparison has two halves. First: Obsidian's own help documentation lists four free ways to sync a vault without paying (iCloud, OneDrive, or Google Drive; Syncthing; Git; and Working Copy) alongside its paid first-party service.² Second: live, always-on, real-time multi-device sync is genuinely useful, and when you want it, someone has to build and run the servers. Obsidian charges $48 a year for it.¹ The argument of this post is not that sync should be free; it is that a local-first note already lives on your device and works offline, so for many people the sync subscription answers a problem they do not have.

How much does Obsidian Sync cost?

Obsidian Sync's Standard plan costs $4 per user per month when billed annually, which works out to $48 a year, or $5 per user per month when billed monthly.¹ The core Obsidian app stays free, "Free without limits. No sign-up required. No strings attached," and Sync is an optional add-on.³ The subscription buys end-to-end encryption and version history.¹

That last detail matters. You are renting a server, not the editor.

Obsidian's editor is free on every platform it supports, and it stores notes as plain Markdown files on your own disk.³ What costs $48 a year is the off-site remote vault that copies those files between devices in real time, secured with AES-256 and carrying version history for every note.¹ The price is fair for what it is, since managed, encrypted, always-on synchronization is real engineering. But it is a recurring cost layered on top of a free app, and that layering is what readers notice. Subscription fatigue is not an Obsidian-specific grievance. "Ask HN: Anyone tired of everything being a subscription now?", submitted by user CM30 on December 18, 2022, reached 931 points and 694 comments, with note-taking apps named explicitly in the first paragraph.⁴

Do you actually need a sync subscription?

Most people who pay for sync are paying to move files between devices they already own — a need a local-first app reframes rather than charges for. If your notes live on your device and work offline, the only open question is how they reach your second device, and there are free answers before there is a paid one.^{2 5}

The reframing is the whole post.

Martin Kleppmann, Adam Wiggins, Peter van Hardenberg, and Mark McGranaghan argued the principle in their 2019 Ink & Switch essay "Local-first software: you own your data, in spite of the cloud."⁵ Two of their seven ideals speak directly to sync: "Your work is not trapped on one device," and "The network is optional."⁵ A local-first note is not waiting on a server to become readable. It is already on the machine in front of you, and the network, when it arrives, is an enhancement that distributes changes rather than a dependency that gates access. Sync, in that frame, is a convenience you add, not a turnstile you pay to pass.

What that convenience is worth depends entirely on your devices. One laptop and one phone you sync once a day is a different problem from four machines you switch between every hour. The honest answer is that some people need always-on real-time sync and should pay for it — a point the "Who should NOT use MNMNOTE" section below makes plainly. But the modal note-taker, syncing occasionally between two devices, is paying a subscription to solve a problem that a free file-sync folder would also solve — or that a single end-to-end encrypted note share would handle.

What are the free ways to sync an Obsidian vault?

Obsidian's own documentation lists four no-cost sync routes alongside its paid service: third-party cloud folders (iCloud, OneDrive, Google Drive), Syncthing for local peer-to-peer sync, Git, and Working Copy.² Because an Obsidian vault is just a folder of Markdown files, any tool that syncs a folder can sync a vault, for free, with trade-offs.

The trade-offs are real, and Obsidian names them.

Folder-based cloud services are the path of least resistance: drop your vault inside an iCloud, Dropbox, or Google Drive folder and the files replicate through the filesystem. Syncthing is the privacy-respecting option: "a continuous file synchronization program" that synchronizes files between computers in real time with "no central server that might be compromised, legally or illegally," free and open source.⁶ Git and Working Copy add version history and conflict resolution at the cost of a developer's mental model. Each works. None is frictionless. Obsidian's help page carries an explicit warning: "Avoid syncing the same vault across multiple services (e.g., using both Obsidian Sync and iCloud simultaneously) to prevent data conflicts or corruption." iCloud Drive on Windows, in particular, is documented to risk file duplication or corruption.²

The free routes are real, and for technical users they are excellent. They are also fiddly, and the fiddliness is precisely what the $48-a-year subscription removes. That is the honest trade: free DIY sync costs setup and vigilance; paid sync costs money. There is no option that costs nothing on both axes.

How does MNMNOTE handle multiple devices?

MNMNOTE is local-first: every note lives on the device in front of you, in your browser, and works fully offline, with nothing sent to a server by default.⁷ To move a note elsewhere, MNMNOTE includes end-to-end encrypted sharing. You send one note over a link, and the text decrypts only in the recipient's browser.⁷

That covers the common case without standing up a sync service. It does not cover every case.

The honest line, stated once and plainly: local-first storage plus per-note encrypted sharing is a different thing from live, always-on, real-time multi-device sync.⁷ What MNMNOTE keeps local is the foundation — your notes on your own device, offline, no account — plus encrypted sharing of any single note you choose to send. If your need is "I wrote this on my laptop and want to read it on my phone," an encrypted share answers it. If your need is "every keystroke on four devices stays continuously merged," that is live sync — a separate capability, with its own engineering behind it.

Real-time multi-device merging is genuine engineering. Keeping every device in sync the instant you type means running and maintaining server infrastructure that resolves conflicts automatically, so two devices edited at once never overwrite each other. That work is real, which is why Obsidian charges $48 a year for its first-party sync rather than bundling it into the free editor.¹ The local-first path sidesteps the need for it in the common case, because the note is already on the device in front of you.

Side-by-side comparison

The table below compares how each path moves notes between devices, not features in isolation, across the three realistic paths: Obsidian Sync, free DIY sync of an Obsidian vault, and MNMNOTE's local-first model. Every cell cites a primary source. Read the Model and Devices rows first, then the encryption and setup-effort rows, since those are where the three paths actually diverge.

The conflict-risk row is the one to read twice. Obsidian's own documentation warns that mixing sync services on one vault can cause "data conflicts or corruption" — the hidden cost of the free DIY path.²

No path is free on every axis.

Who should use MNMNOTE?

Use MNMNOTE if you want local-first markdown that works offline and need to move individual notes between devices or people more often than you need every device continuously merged. It opens in any browser, no install and no account, stores notes locally, and shares any single note end-to-end encrypted over a link.⁷

The match is about how you actually move notes.

If your real workflow is "write on one device, occasionally read or send on another," MNMNOTE's local-first model — notes on your own device plus encrypted per-note sharing — answers it without configuring a sync service at all. It runs on a Chromebook, a locked-down work laptop, or a phone browser, because it asks nothing of the operating system.⁷ The same browser-first argument I made in the MNMNOTE vs Obsidian browser comparison applies here: the runtime nobody has to install is the one already open in a tab. And because MNMNOTE reads and writes plain Markdown, your notes remain portable — the durability argument from why your notes should outlive your app holds regardless of how you move them between devices.

Who should NOT use MNMNOTE?

Do not use MNMNOTE if your top requirement is always-on, real-time, multi-device sync with no configuration and no cost. No app delivers continuous live sync for free — the servers and the conflict-resolution engineering have to be funded somehow, which is why Obsidian charges $48 a year for its first-party Sync.¹ If continuous, zero-config sync is non-negotiable, use Obsidian with a free DIY route such as Syncthing or Git, accepting the setup effort, or pay for Obsidian Sync.^{2 6}

This is the trust-builder, so it is stated without hedging.

If you live across four devices and want every keystroke merged the instant you make it, with no configuration and no money changing hands, no app delivers that — the servers and the real-time merging engineering have to be paid for somehow. Obsidian's free DIY paths (Syncthing, Git, iCloud) cost setup time and carry the conflict risk Obsidian itself documents.² Obsidian Sync costs $48 a year and removes that friction. MNMNOTE's model is local-first — notes on your own device plus encrypted per-note sharing — which is a different capability from continuous cross-device sync, not a cheaper version of it.⁷ Among the sync routes, pick the cost you would rather pay — money or setup — but no path removes every trade-off.

Frequently Asked Questions

These are the questions people type when Obsidian Sync's price gives them pause. Each answer is short enough to lift on its own and sourced to Obsidian's published pages or MNMNOTE's committed positioning. Read the first and fourth if you read only two — they carry the honest core of this comparison.

How much does Obsidian Sync cost? Obsidian Sync's Standard plan costs $4 per user per month billed annually, which totals $48 a year, or $5 per user per month billed monthly.³ The core Obsidian app is free. Sync is an optional add-on that buys an off-site encrypted remote vault, AES-256 encryption, and per-note version history.¹

Is there a free Obsidian Sync alternative? Yes — Obsidian's own help page documents four free routes: iCloud, OneDrive, or Google Drive folders; Syncthing; Git; and Working Copy.² All sync a vault for free because the vault is a folder of Markdown files. The trade-off is setup effort and conflict risk, which Obsidian warns can cause "data conflicts or corruption."²

How does MNMNOTE handle multiple devices? MNMNOTE is local-first: every note lives on the device you wrote it on, stored in your browser, and works fully offline, with nothing sent to a server by default.⁷ To move a note elsewhere, it includes end-to-end encrypted sharing of any single note over a link — the text decrypts only in the recipient's browser. That is per-note sharing, which is a different capability from continuous cross-device sync.⁷

What is the best alternative to Obsidian Sync? The best alternative depends on your devices. For occasional two-device use, a free DIY route (Syncthing or a cloud folder) or MNMNOTE's local-first model with encrypted per-note sharing is enough.² For continuous always-on sync, Obsidian Sync at $48 a year is the low-effort answer.¹

Why is Obsidian Sync so expensive? Obsidian Sync is not unusually priced — $48 a year for managed, AES-256-encrypted, version-tracked synchronization is competitive.¹ It feels expensive because it is a recurring subscription on top of a free app, and subscription fatigue is widespread: an Ask HN thread on the topic reached 931 points in December 2022.⁴ The friction it removes is real; so is the recurring charge.

Does MNMNOTE work offline without any sync? Yes. MNMNOTE is local-first: after the first visit it runs entirely in your browser, with notes stored on your own device and never sent to a server by default.⁷ It works fully offline on its own; to move a note to another device, you send it as an end-to-end encrypted per-note share.⁷

Can I use Syncthing to sync Obsidian for free? Yes. Obsidian's documentation lists Syncthing as a supported local sync method.² Syncthing is "a continuous file synchronization program" that is free, open source, and keeps data only on your own computers with "no central server."⁶ The cost is setup and the conflict-avoidance care any folder-sync route requires.

The best sync is the one you don't need. A local-first note already lives on your device and works offline, which turns sync from a turnstile you pay to pass into a convenience you add when the second device shows up.

The best sync is the one you don't need. MNMNOTE (mnmnote.com) is built local-first, so your notes stay on your own device, offline, with end-to-end encrypted sharing of any single note you choose to send.
