CookieCloud Hosting Live In 5 Minutes

CookieCloud hosting on xCloud gives you a self-hosted cookie sync server on your own domain, for the CookieCloud browser extension. Deploy CookieCloud from the OneClick catalog and xCloud starts the pinned image, mounts a volume for the encrypted sync files and publishes the API over HTTPS. The extension encrypts cookies and local storage in the browser, so the server stores only ciphertext, and it has no login or web interface.

What is CookieCloud?

CookieCloud is a small tool for syncing cookies with your self-hosted server, according to its README, so browser cookies and local storage can reach another browser or your phone. It has built-in end-to-end encryption and lets you set a synchronisation interval. Upstream says sync is one-way, with one browser uploading while another downloads, and that the extension officially supports Chrome and Edge. Self-hosted CookieCloud is the server half of that pair, a cookie sync server you run yourself. It is licensed under GPL-3.0.

On xCloud this template deploys the easychen/cookiecloud Docker image, tag 2023.01.20.16.39, pinned by digest. The server has no accounts, no login and no web interface, and the site address shows only a short Hello World line. It stores one encrypted file per sync ID on the cookiecloud_data volume, and the sync ID is the only access secret.

From Sign-Up to a Live Sync Server In Just 3 Easy Steps

A CookieCloud server normally means a container, a data volume, a reverse proxy with a raised upload limit, a domain and a certificate before the first sync. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick CookieCloud from the OneClick catalog. Choose your domain and target server — there are no extra fields to fill in.
Step 02
We Deploy It For You
One click. We bring up the single CookieCloud container from the upstream image, pinned by immutable digest, mount the cookiecloud_data volume that holds one encrypted JSON file per sync ID, raise the upload limit to 50 MB and publish the API over HTTPS on your domain. There is no database to set up.
Step 03
Point The Extension At It
Install the CookieCloud extension in Chrome or Edge, enter your HTTPS server address in its settings, set a long random sync ID and a strong password, then run a first sync. Opening the address in a browser shows only a short "Hello World" line.

Everything CookieCloud Does, On Your Own Server

CookieCloud runs in full here: the sync API the browser extension talks to, with its encrypted files kept on storage you own.

Cookie And Local-Storage Sync
The extension backs up cookies and local-storage data to your server so another browser or tool can fetch them later.
Encrypted In The Browser
The extension encrypts the data on your device and uploads only the ciphertext. The server never receives the encryption password.
Sync ID As The Access Secret
The extension generates a sync ID (UUID) on your device, and the server keeps one encrypted file per ID. There are no accounts to manage.
Uploads Up To 50 MB
The proxy in front of the server is configured to accept uploads of up to 50 MB per sync.
Optional Path Prefix
Set API_ROOT to serve every route under a prefix such as /cookie, then enter the full prefixed address in the extension.
No Database To Run
A single container with no database or migration step; it is ready seconds after install and measured about 80 MiB idle in QA.

What You Can Do With CookieCloud

Keep browser sessions across devices
Sync cookies and local-storage between browsers through your own server instead of a third-party service.
Back up browser data you would rather not lose
Keep an encrypted copy of cookie and local-storage data on a volume you can back up with the rest of your server.
Feed other tools that read the sync data
Another browser or tool that knows the sync ID and password can fetch the encrypted data later.
Share one sync server with trusted people
Run one server for your own devices or a small group, with each person using their own long random sync ID and password.

CookieCloud vs Alternatives

Chrome sync: Google describes Chrome sync as signing in to get your saved info, such as bookmarks and passwords, on all your devices, kept in your Google Account. CookieCloud is for people who want cookie and local-storage backups encrypted and held on a server they run instead.
Exporting cookies by hand: Manual export and import moves data once. CookieCloud keeps an encrypted copy on your server that the extension can sync again whenever you set it to.
Vaultwarden: Vaultwarden has its own OneClick page. CookieCloud handles browser cookie and local-storage data and is not a password vault.
Syncthing: Syncthing has its own OneClick page. CookieCloud syncs encrypted browser cookie and local-storage data through an extension and one server, not general files.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Is CookieCloud free?

Yes. CookieCloud is open source under GPL-3.0, with the licence linked from this page on the default branch, because upstream has no tag matching the pinned image. xCloud bills for the Cloud VPS under it, not for CookieCloud, and there is no per-device fee.

Can you self-host CookieCloud with Docker?

Yes, and this CookieCloud Docker hosting template does it for you: the easychen/cookiecloud image, pinned by digest, is a single container on your own server, with HTTPS in front of port 8088. The image is the only one the project publishes, built from its docker folder in January 2023.

How much RAM does CookieCloud need?

The manifest lists a floor of 128 MB of RAM, one CPU core and 1 GB of disk, because there is no database. Stored data grows with the number of sync IDs you use. This page sells the 6 GB tier, so there is plenty of room above that floor.

Which browsers work with the CookieCloud extension?

Upstream says the extension officially supports Chrome and Edge, and that other Chromium-based browsers might work but are untested. Firefox needs a build you compile yourself. Install the extension, open its settings and enter your HTTPS server address, then set a sync ID and password.

Does the CookieCloud server see my cookies?

No. The extension encrypts cookies and local storage in the browser and uploads only ciphertext, and it creates the sync ID and encryption password on your device. The server stores one encrypted file per sync ID. Keep the password strong, because the blob is only as safe as it.

Is a self-hosted CookieCloud server public?

Yes, by default. There is no login: anyone who knows the address can upload data, and anyone who knows a sync ID can download its encrypted blob. Use a long random sync ID and strong password, keep the address private, and add Basic Authentication yourself if you want a gate.

Is there a limit on how much can be stored?

Each upload may be up to 50 MB, but there is no limit on how many files are stored. A stranger who finds the address could fill the server disk, so keep the address private and watch disk use. Deleting the site removes the volume and everything on it.

Is CookieCloud sync one-way?

Upstream says synchronisation is currently one-way, meaning one browser uploads while another downloads. The pinned image is from January 2023, and its server-side decrypt endpoint supports only the legacy cipher, so check that your extension version works with it before you depend on it.

How do I back up CookieCloud?

Back up the cookiecloud_data volume, mounted at /data/api/data, which holds one encrypted JSON file per sync ID. The server never sees your password, so keep the sync ID and password somewhere safe too. Test a restore on a disposable install before relying on it.

Backup and restore Docker apps

Can I serve CookieCloud under a path prefix?

Yes. Set API_ROOT in the Environment editor, without a trailing slash, for example /cookie, then Save and Redeploy. Every route then moves under that prefix, so enter the full prefixed address in the extension. Leave it unset to serve from the root of your domain.

How do I upgrade CookieCloud?

A running install keeps its pinned image when the catalog changes; adopting a newer template version is up to you. Back up the volume first. Later server source changes, such as a health endpoint and rate limiting, are not in this build, so read upstream before moving.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
