Konode
Add to Chrome
No server. No telemetry. Open source.
Bookmarks, tabs, history and your extension list, in step across every Chromium based browser. Stored in your own Google Drive, GitHub or WebDAV, with no Konode account and no server in between.
What syncs
Your whole tree lands on every device with the folders and the nesting intact. Add one on the laptop and it is on the desktop, so the organising you already did stays done.
Close the laptop mid-thought and pick the same tabs back up on another machine. Save a set, restore it wherever you land. Your session stops belonging to one device.
That page you found last week is still there on the machine you are sitting at now. One de-duplicated list instead of one per device, so searching your history finds things.
Set up a new machine and see at a glance which of your extensions are missing from it. Konode keeps the list in step, and never installs or removes a thing by itself.
When two devices disagree, you choose how it's resolved: newest wins, always prefer this device, always prefer the other, or resolve it yourself from the popup.
Your storage
Three backends underneath: Google Drive, a GitHub repository, or any compliant WebDAV server. Everything below is one of those three, so if your provider speaks WebDAV, it already works.
Signs in with your own Google account and asks only for the narrow drive.file scope, so Konode can touch the files it created and nothing else in your Drive.
Point it at a single private repository with a fine-grained token. Every sync lands as a commit, so you get a version history you can read, diff, and roll back by hand.
Connects over WebDAV, so your sync files sit on the server you already run. Use an app password rather than your account login, especially with two-factor on.
Turn on WebDAV access in your pCloud account and paste the endpoint into Konode. It writes into one folder you pick and leaves the rest of your drive alone.
Koofr exposes a WebDAV endpoint, so it works the same way. Generate an app password for it and your main Koofr login never goes into the extension.
Fastmail's file storage speaks WebDAV too. Same three fields as any other server: endpoint URL, username, and an app password scoped to files.
Turn on the WebDAV Server package in DSM and point Konode at it. The one option where storage you own is literal, because the disk is in your house.
The generic route, and the one the five above travel on. Any compliant server works, kDrive included. No provider-specific code and nothing to lock you in.
If your provider exposes WebDAV, it already works, so try it first. If not, open an issue and name it. That is how MEGA got on the roadmap.
End-to-end encryption
Encryption is optional and stays off until you set a passphrase. Switch it on and every file Konode writes is sealed on this machine first, so the provider holding it is holding something it cannot read.
Inside your browser
The same one on every device you sync, typed in on each. Konode keeps no copy of it and has nowhere to keep one.
On this machine, from that passphrase. It never crosses the network in either direction, so there is no moment at which it could be intercepted.
Bookmarks, tabs, history and your extension list become ciphertext before a single byte is uploaded.
What your storage provider receives
Encryption off
"title": "Mortgage rates 2026", "url": "https://…"
Encryption on
"payload": "9f3c7a1e5d2b8c4f…"
Konode never gets the key, and there is no Konode server to send it to.
That cuts both ways, and it is meant to. Nobody can read these files back without the passphrase, and nobody includes you. Turning encryption on also only changes what gets written from then on, so delete anything already synced in readable form if you want none of it left.
Privacy & security
Three parties can touch your synced data. Here is exactly how much of it each one gets, with encryption off and with it on.
On any device you have signed in on, with the passphrase you chose.
Google, GitHub, or whoever runs the WebDAV server you pointed Konode at.
The extension you install, and us, the people who wrote and publish it.
Two stops, and with a passphrase set, ciphertext for the whole crossing between them. Every other sync tool keeps a server in the middle of this picture. There is nothing to put there.
Step 1, on your device
Konode reads the streams you switched on and, if you set a passphrase, encrypts them here. The key is derived on this machine and never leaves it.
Step 2, your account
The file lands in your own Drive, repository or WebDAV folder. With a passphrase set it arrives as ciphertext that nobody can read back without it.
Konode installs able to read one thing. The browser only prompts for the rest when you switch that stream on, so anything you leave off stays unreadable. Try it.
Known limits
A threat model that only lists wins is marketing. These are the three places where Konode cannot help you, stated before you install rather than after something goes wrong.
Browser extensions cannot reach the operating system keychain, so your backend credentials sit in ordinary local extension storage. Anyone using your unlocked profile can read them.
Encryption keys are derived on your device and never leave it. Lose the passphrase and the uploaded data cannot be decrypted, by you or by us. There is nothing to reset.
Encryption hides what is inside a file, not that the file exists. Your provider can still see file names, sizes and when they last changed, whether encryption is on or off.
The file format
{
"device": "laptop",
"type": "bookmarks",
"updated": "2026-07-27T09:41:00Z",

}Alongside itlaptop-tabs.jsondesktop-bookmarks.jsondesktop-history.json
This is an illustrative shape. The repository has the exact schema. Every sync pulls each peer's file, merges non-destructively, then pushes back. Bookmarks use tombstones so deletions travel between devices without resurrecting old entries.

Questions
No. There is no account to create and no Konode server to sign in to, because there isn't one. You connect storage you already have, and that is the setup.
Chrome, Brave, Helium and ungoogled-chromium through the Chrome Web Store, and Firefox through Firefox Add-ons. The two can sit a patch apart while a release clears review. The roadmap has the detail.
Three backends: Google Drive, a GitHub repository, or any compliant WebDAV server. Nextcloud, ownCloud, Synology, pCloud and kDrive all qualify. The setup guide walks through each.
On your device only, in the browser's local extension storage. They authenticate to the backend you chose and are never transmitted to us. There is no server to transmit them to.
Then the uploaded data cannot be decrypted, by you or by anyone else. No Konode server holds your key, so there is nothing to reset and no recovery path.
Two places, both yours. Uninstalling clears what the extension put on your device, credentials included. Deleting Konode's folder on your own backend clears the synced files. There is no third place.
