Why I Built EiraSync: The Zero-Hassle Obsidian Sync

The personal story behind EiraSync, our strict privacy architecture, and the roadmap for a better Obsidian synchronization experience.

Hi, I'm Simon, the founder of EiraSync. I use Obsidian every single day. It's my knowledge base, development log, and the place where I plan products and write ideas. But for a long time, keeping my vault synced across my phone and laptop never felt reliable enough for my workflow.

I didn't want to pay a premium subscription, and standard cloud drives like iCloud occasionally led to file conflicts.

So, I decided to build the solution I wished already existed.

The Motivation: My CouchDB Struggle

If you've looked into Obsidian sync alternatives, you've probably found the Self-hosted LiveSync plugin. It's a brilliant piece of open-source engineering. But there's a huge catch: you have to host your own CouchDB server.

I spent hours setting up Docker containers, fighting with reverse proxies, and fixing SSL certificates just to get my notes to sync. And when something broke, I had to drop my actual work to play system administrator.

I realized: I just want to write notes, not manage databases.

What EiraSync Actually Is

EiraSync is a fully managed backend for the Obsidian LiveSync plugin. Instead of setting up and maintaining your own CouchDB server, you simply create an account, copy your setup link, and start syncing.

LiveSync continues to handle the synchronization and end-to-end encryption locally on your device; EiraSync takes care of the cloud infrastructure behind it. You're up and running in under two minutes.

My Privacy Promise: Zero-Knowledge & EU Hosted

My Obsidian vault contains some of my most important information—business ideas, product roadmaps, and personal journals. I refuse to hand that data over to a server in plain text, and I don't expect you to either.

Privacy isn't just a marketing feature for EiraSync; it's the absolute foundation of the architecture:

  • End-to-End Encryption (E2EE): Your data is encrypted locally on your device by the LiveSync plugin before it ever leaves your network.
  • Zero-Knowledge Architecture: EiraSync only stores ciphertext. I don't have your encryption keys, so I can't access the contents of your notes.
  • Strict EU Hosting: Your encrypted vault data is hosted exclusively on servers located in Germany. Some supporting infrastructure—such as our website CDN and transactional email delivery—relies on trusted global providers with appropriate EU data protection safeguards. Your encrypted notes themselves never leave the EU.

End-to-end encryption flow: laptop encrypts, EU server stores ciphertext, phone decrypts
Obsidian encrypts on your laptop, the EU server stores ciphertext only, and your phone decrypts locally.

The Plan: Doing One Thing Perfectly

EiraSync is a small, focused, and independent project. My goal isn't to build a huge ecosystem—it's to build the most reliable sync experience possible.

You can expect:

  • High Availability: Because I know how annoying it is when you need a note right now and the server is down.
  • Frictionless Onboarding: Continuously making the setup easier for everyone, regardless of their technical background.
  • Honest Communication: If something breaks, I will tell you exactly what happened and how I'm fixing it.

I built EiraSync because I wanted syncing to disappear into the background. Your notes should simply be there—on every device, every time. That's the experience I'm building.

If EiraSync sounds like the kind of sync solution you've been looking for, I'd love for you to try it. Start your 14-day free trial today.
