RustiCal Hosting Live In 5 Minutes

What is RustiCal?

RustiCal is a CalDAV and CardDAV server. CalDAV and CardDAV are the open standards that calendar and contacts apps use to sync, so one RustiCal server can serve your phone and your desktop apps. It keeps everything in one SQLite database and ships as an image holding a single program, which is why it needs so little to run. The code is open source under AGPL-3.0.

On xCloud it is RustiCal 0.18.0 from the official image, pinned by digest. There is no sign-up page: your first account is created once, from the username you choose and a generated password, and RustiCal has no administrator role, so each account manages its own calendars and contacts. Calendars and events live in the rustical_data volume. Upstream says the project is under active development.

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

A calendar and contacts server normally means a container, a database file, a first account, a volume, a domain and a certificate before your phone can sync. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick RustiCal from the OneClick catalog. Choose your domain and server, then enter the username for your first account (the default is admin).
Step 02
We Deploy It For You
One click. We start the official RustiCal image, pinned by digest, keep its SQLite database on the rustical_data volume, generate a 32-character password for your first account and publish it over HTTPS.
Step 03
Sign In And Connect
Save the username and password from your installation credentials, open /frontend and sign in. Create a calendar or address book, then add https://your-domain/caldav to your phone or desktop app with the same login.

Everything RustiCal Does, On Your Own Server

RustiCal runs in full here: calendars and contacts that sync with the apps you already use, kept on a server you own.

Calendars And Contacts In One Place
One server holds your calendars and address books, and your phone and desktop apps sync with it through a single address, /caldav.
A Small Web Interface
Create calendars and address books, import existing calendars and export each calendar from your browser at /frontend.
Near-Instant Sync With DAVx5
WebDAV Push lets DAVx5 and compatible apps pick up changes almost at once instead of waiting for the next check.
Private To Each Account
Only people with an account can see or change calendars and contacts. Anyone else gets a sign-in prompt.
Optional Single Sign-On
RustiCal supports OpenID Connect and can turn off password login. It is optional and switched on through the environment settings.
Easy App Discovery
Apps that cannot use the /caldav address directly can find it at /.well-known/caldav, and apps that use a Nextcloud-style login are supported.

What You Can Do With RustiCal

Sync your calendar across devices
Keep events on your own server and see them on your phone and your desktop calendar.
Keep contacts private
Store address books on a server you control instead of with a hosted contacts service.
Move an existing calendar over
Import a calendar you already have through the web interface and export any calendar whenever you want a copy.
Get changes on your phone quickly
Use WebDAV Push with DAVx5 so new and edited events show up almost at once.

RustiCal vs Alternatives

Google Calendar and iCloud: Hosted calendar services keep your events and contacts on the provider's servers. RustiCal stores them in a SQLite database on your own Cloud VPS and syncs over open CalDAV and CardDAV.
Radicale: Radicale has its own OneClick page. It is another CalDAV and CardDAV server you can run on your own domain.
Baikal: Baikal has its own OneClick page. It is another CalDAV and CardDAV server. RustiCal has no administrator role and keeps its data in one SQLite database.
Nextcloud: Nextcloud has its own OneClick page. It is a broader suite that also offers calendars and contacts, whereas RustiCal does only CalDAV and CardDAV.

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.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

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

Can I run RustiCal in Docker?

Yes, and this template is RustiCal Docker hosting without the setup: the official RustiCal 0.18.0 image pinned by digest, a persistent volume for its SQLite database, a generated first-account password and HTTPS on your own domain.

How much RAM does RustiCal need?

The template baseline is 256 MB of RAM, 1 CPU core and 2 GB of disk. RustiCal is a single program with an embedded database, so it uses little memory when idle. The 6 GB plan is the starting point here, well above that baseline.

How do I sign in to RustiCal?

Open /frontend on your domain and use the username you chose at install and the generated password from your installation credentials. There is no public sign-up page, so nobody else can create an account.

How do I connect my phone or desktop app?

Use https://your-domain/caldav as the CalDAV and CardDAV server address, with the same username and password. DAVx5 users can also use WebDAV Push for near-instant sync.

How do I add more accounts or change a password?

The username and password you set at install are used only once, to create the first account. Changing them in the environment later does not change the account. Use RustiCal's command line (the principals command) to add accounts or change passwords.

Can I use single sign-on?

RustiCal supports OpenID Connect and can disable password login. It is optional and set through commented-out environment settings. Fill in a complete set of values, then Save and Redeploy, because RustiCal will not start with a half-filled block.

Is RustiCal free?

Yes. RustiCal is open source under the AGPL-3.0 licence, so the software has no licence fee. You are billed only for the dedicated Cloud VPS that runs it.

How do I back up RustiCal?

This template does not make backups. Export each calendar from the web interface, and to copy the whole database, stop the container first and copy the rustical_data volume. Never use docker compose down -v, which deletes the volume.

Backup and restore Docker apps

Do I stay signed in after a restart?

No. Web sign-in works over HTTPS only, and everyone is signed out whenever RustiCal restarts. Your calendars and events stay on the volume and were still there after a restart in testing.

How do I upgrade RustiCal?

The install stays on its pinned 0.18.0 image until you adopt a newer template version. Back up your calendars first and read the upstream release notes. Existing sites are never upgraded automatically, and the redeploy keeps the rustical_data volume.

Is there an upload limit?

Yes. Uploads and calendar imports are limited to 4 MB per request by default, which is RustiCal's own default.

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.
