Cerbos Hosting Live In 5 Minutes

Deploy Cerbos hosting and move authorization decisions out of your application code. xCloud runs the pinned Cerbos 0.56.0 official image as a single container, publishes the HTTP API and API explorer over HTTPS, exposes the gRPC API on a TCP port, and mounts a persistent policy volume — policy changes are picked up within seconds with no restart.

  • No terminal
  • No technical skills needed
  • No lock-in, cancel anytime

What is Cerbos?

Cerbos is an open-source authorization policy decision point. Your applications send it a question — may this principal perform this action on this resource? — and it answers from policies written as YAML.

This deployment runs the official image as one container with an HTTP API and API explorer, a gRPC API and a policy directory on a persistent volume. Cerbos is licensed under Apache-2.0.

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

A policy decision point normally means a container, a policy directory, a TLS-terminating proxy and a domain before the first check request. This is the same result without assembling any of it.

  1. Step 01

    Sign Up

    Create your xCloud account and pick Cerbos from the OneClick catalog. Choose your domain and target server — there are no extra fields and no generated credentials.

  2. Step 02

    We Deploy It For You

    One click. We bring up the official Cerbos image, pinned by immutable digest, as a single container with no database, mount the cerbos_policies volume at /policies, publish the HTTP API and API explorer over HTTPS and expose the gRPC API on a public TCP port. Anonymous telemetry is turned off.

  3. Step 03

    Add Policies And Try A Check

    Open your HTTPS Cerbos URL to reach the API explorer; the install shows the HTTP API base URL, health check and gRPC address. Then copy your YAML policies into the container over SSH with docker cp — the server loads them without a restart.

Everything Cerbos Does, On Your Own Server

Cerbos runs in full here: an authorization policy server on your own domain, reading YAML policies from a volume you own.

  • RBAC And ABAC Decisions

    Centralise role-based and attribute-based authorization decisions outside your application code.

  • Policies As YAML

    Write policies as YAML with derived roles, conditions and query plans, and keep them in version control.

  • Live Policy Reloads

    Policy changes are picked up within seconds with no restart; this was checked by adding a policy to the running server.

  • Built-In API Explorer

    An API explorer is served at the site root for trying check requests.

  • HTTP And gRPC APIs

    The REST API is under /api with health at /_cerbos/health, and a gRPC endpoint serves service-to-service calls.

  • Persistent Policy Volume

    The cerbos_policies volume survives an xCloud Restart; the same decisions were returned after a restart in QA.

Everything You Need To Run Your Policy Server 24/7

Managed hosting for Cerbos, so the parts that keep it online are not your problem.

  • Cerbos 0.56.0 deployed instantly
  • Official image pinned by digest
  • Single container, no database
  • HTTP API and gRPC endpoint
  • Anonymous telemetry turned off
  • Kept behind xCloud nginx
  • Free SSL certificate
  • Server backups and snapshots
  • Server security updates included
  • 30+ server locations
  • Unused balance refunded

What You Can Do With Cerbos

  • Centralise RBAC

    Keep role-based access rules in one policy set instead of scattered if-statements across services.

  • Add attribute-based rules

    Express conditions on attributes of the principal and the resource, with derived roles, in YAML.

  • Serve many services from one server

    Let backend services call the gRPC endpoint for decisions while browser apps from your domain use the HTTP API.

  • Review policies like code

    Keep policies in version control and copy them into the volume, so authorization changes go through the same review as code.

Cerbos vs Alternatives

OpenFGA
OpenFGA is a relationship-based authorization system; Cerbos decides from YAML policies written against roles and attributes.
Keycloak
Keycloak is an identity and login provider; Cerbos has no accounts or login and only answers authorization questions.
Authorization checks in application code
Checks written inline live in each service; Cerbos moves them into policies that are versioned and reloaded separately.

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!

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.

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

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.

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.

How do I sign in?

There is no sign-in. Cerbos has no user accounts; protect access at your proxy or firewall if needed.

How do I add policies?

Copy YAML policy files into the policy volume over SSH, for example with docker cp. Cerbos watches the directory and reloads without a restart.

Why is every check denied after install?

The policy store starts empty, so every check is denied until policies are added.

What runs alongside Cerbos?

Nothing. It is a single container with no database.

Who can send check requests?

Anyone who can reach the domain or the gRPC port. The admin API is off, so policies cannot be changed through the API; add Basic Auth or IP restriction in front of the domain if it should not be public.

How is the gRPC port exposed?

The gRPC API (plain HTTP/2) is published on a public TCP port. You open your own firewall for it, ideally restricted to your application servers.

Can browser apps call the API?

Calls from the site's own domain are allowed; add one more origin with EXTRA_CORS_ORIGIN and redeploy.

Does the API explorer need internet access?

The explorer loads its viewer script from unpkg.com, an upstream external dependency.

What should I back up?

The cerbos_policies volume, or your policy files from version control.

Does xCloud automatically back up or update Cerbos?

No. The template pins Cerbos 0.56.0 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Back up first, read the upstream release notes, then bump the readable tag and digest together on your own schedule. Server-level backups and snapshots are available on every Cloud VPS.

What are the server requirements, and why does this page sell 6 GB?

The template's baseline asks for 1 CPU core, 256 MB of RAM and 1 GB of disk; measured idle use in QA was about 21 MiB. This page sells the 6 GB tier as the entry rung, with real headroom above that baseline.

Is xCloud officially partnered with Cerbos?

No. No official partnership or endorsement between xCloud and the Cerbos project has been verified. This is a deployment and server-management option for the open-source Cerbos project.

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.
