Welcome to SyncBins

A quick tour that gets you from sign-up to syncing between your phone and laptop in under three minutes.

What is SyncBins?

Ever copy a link on your phone and wish it was on your laptop? Screenshot something and email it to yourself? Text yourself a password? SyncBins is the fix.

It’s a private drop box between your own devices — paste a link, drag a photo, save a password, jot a note, record a voice memo. Whatever you drop in appears on every device you’ve paired, instantly.

There’s no sharing, no teams, no social features. The only person who ever sees your stuff is you.

How it's organized

Bins are folders you put things into (like “Inbox” or “Work”). Items are the things you save. Devices are your phone, laptop, browser — anything you’ve paired. Items sync to every device automatically.

What makes it different?

Everything you save is end-to-end encrypted before it leaves your device. The server never sees your passwords, notes, or files — only scrambled bytes. Even if someone broke into the server, they’d find nothing readable. Your 12-word recovery phrase is the only key, and it never leaves your hands.

You don’t need to understand the cryptography to use SyncBins — it all happens in the background. But if you’re curious, there’s a full breakdown in How encryption works.

Get started in three steps

1. Finish first-time setup — run the onboarding wizard, back up your recovery phrase, and register your first device.
2. Add your first item — paste a link, drag a screenshot, or type a note.
3. Pair another device — type six words from your first device to connect a second one.

Hosted or self-hosted?

Both work identically. The only difference is who runs the server:

Hosted · syncbins.com

We run the server. Free for 2 devices and 1 GB; Pro at $10/mo (founder pricing, locked) adds unlimited devices and 50 GB. Nothing to install — just sign up.

Self-hosted

Run it yourself. MIT-licensed, one Docker command on any $4 VPS, homelab, or Raspberry Pi. See the Self-Hosting quick start.

Your recovery phrase matters

During setup you’ll see a 12-word recovery phrase. This is the only way to get back into your bins if you lose all your devices. The server never sees it. We can’t reset it for you.

Back it up now

Write it down on paper. Store it in your password manager. Both, ideally. If you lose the phrase and every paired device, your data is gone — that’s the trade-off of true end-to-end encryption.
