Syncs everything. Sees nothing.
Leave your desk mid-article — it's already open on the couch. Lidless makes all your computers feel like one browser. Automatic, instant, encrypted.
For Chrome & Firefox on desktop
Every device. Always in sync.
A unified browser experience.
What we can — and can't — see.
Most sync tools ask you to trust a promise. Lidless is built so it doesn't need one: your tabs are locked with a key that only you hold.
What we can't see
- Your tabs — the URLs, titles, and order you sync
- Your browsing history or which sites you visit
- Your master password — it never reaches us, even during sign-in
Everything is encrypted on your device before it leaves. What reaches us is locked — and we don't have the key.
What we do store
- Scrambled blobs — the encrypted version of your tabs, which we have no key to open
- Your email — only if you choose to create an account
Accounts are optional; Lidless syncs fine without one. Full privacy policy →
Three steps. About a minute.
Generate a key
On your first device, Lidless mints a private sync key. It's yours — back it up; it's the only thing that can read your tabs.
Pair a device
Add another browser with a short pairing code or a setup link that never touches our servers. The same key, everywhere.
Your tabs follow
Open something on your laptop, find it on your desktop — already there, right where you left it. Close it once, it's closed everywhere.
Feels like one browser. Priced like a coffee.
Both plans encrypt everything, always. Premium is the jump from "they'll show up in a bit" to already there — live, down to the page, the instant you switch devices.
- Sync across all your computers
- Follows you site to site
- Updates on a timer — a short wait between devices
- End-to-end encrypted
- Everything in Free, instant
- Live sync — changes land the moment you make them, no waiting
- Follows every page, not just every site — resume exactly where you left off
- Encrypted key recovery + first access to new features
Common questions.
Do I need an account?
No. Lidless syncs with just its private key — install, pair, done. An account is optional: it adds password sign-in, key recovery, and Premium billing. You can add one later without starting over.
Can you see what I'm browsing?
No. Your tabs are encrypted on your device before they leave it, and only your devices hold the key. The details are in what we can — and can't — see.
What if I lose my sync key?
Your tabs are never lost — they're still right there in each browser. With an account and your recovery code, you can restore access; without one, you generate a fresh key and pair your devices again in a minute.
Which browsers does it work with?
Chrome and Firefox on desktop today. More to follow.
What does Premium actually change?
Speed and precision. Free syncs on a short timer and follows you site to site. Premium lands changes the instant you make them and follows every page — the difference between "it'll show up" and "it's already there". See pricing.
