Microcks Hosting Live In 5 Minutes

Deploy Microcks hosting and give your team a self-hosted API mocking and testing platform with shared, live mocks and contract tests on your own domain. xCloud runs the pinned Microcks 1.15.0 stack with Keycloak sign-in already wired, a private MongoDB 8.0 and PostgreSQL 17, generated admin passwords, persistent volumes and HTTPS on both the Microcks and Keycloak domains. gRPC mocks and the async minion are not included.

What is Microcks?

Self-hosted Microcks is a platform for turning your API and microservices assets, such as OpenAPI specs, AsyncAPI specs, GraphQL schemas, Postman collections and SoapUI projects, into live mocks in seconds. Its README says it also reuses those assets to run contract conformance and non-regression tests against your API implementation, with CLI integrations for Jenkins, GitHub Actions and Tekton. It stands in for hosted mock services such as Postman Mock Servers, under the Apache-2.0 licence.

On xCloud the template runs the Microcks 1.15.0 stack with Keycloak and its PostgreSQL, MongoDB, a Postman test runtime and a small nginx, all pinned by immutable digest, with persistent volumes. HTTPS is published on two domains, Microcks and Keycloak. gRPC mocks and the async minion, which upstream uses for Kafka, MQTT, AMQP and WebSocket mocks, are not part of this template.

From Sign-Up to Live API Mocks In Just 3 Easy Steps

A Microcks stack normally means the app, MongoDB, Keycloak with its own database, a realm import, two domains and certificates before the first mock. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Microcks from the OneClick catalog. Choose a domain for Microcks and one for the Keycloak sign-in, and your target server — there are no other fields to fill in.
Step 02
We Deploy It For You
One click. We bring up Microcks 1.15.0 by immutable digest with Keycloak and its PostgreSQL 17, MongoDB 8.0, the Postman test runtime and a small nginx in front of Keycloak, all on a private network. The microcks_mongo and microcks_keycloak_db volumes are mounted, the admin passwords are generated, and both domains are published over HTTPS. The first boot builds Keycloak and imports the Microcks realm, which takes a few minutes.
Step 03
Import Your First API
Save the Microcks and Keycloak admin credentials from the protected installation credentials, open the Microcks domain and sign in as admin — you are sent to Keycloak and back. Then import your first API artifact and call its mock endpoint.

Everything Microcks Does, On Your Own Server

Microcks runs here with its sign-in and storage in place: import API artifacts, serve mocks and run conformance tests from one workspace.

Live Mocks From API Specs
Import OpenAPI, GraphQL, Postman and SoapUI artifacts and get live mock endpoints under /rest, /graphql and /soap on your Microcks domain.
Contract Conformance Tests
Reuse the same artifacts to run conformance and non-regression tests against a real API implementation; upstream provides a CLI for CI tools such as Jenkins, GitHub Actions and Tekton.
Keycloak Sign-In Wired In
The Microcks realm and an admin account are created for you, and you add teammates from the Keycloak admin console at /admin/ on the sign-in domain.
Mocks On Your Own HTTPS Domain
Mock endpoints are served on your Microcks domain, so teams outside your network can call them from anywhere.
Persistent Mocks And Users
Imported services, mocks and Keycloak users sit on named volumes and survived a restart of all containers in the verify run.
Private Services
MongoDB, PostgreSQL for Keycloak, the Postman test runtime and the Keycloak nginx publish no host port.

Microcks vs Alternatives

Postman Mock Servers: Postman Mock Servers is Postman's hosted mock service. As a microcks alternative to postman mock servers, Microcks runs on your own Cloud VPS and imports Postman collections as well as OpenAPI, GraphQL and SoapUI assets.
WireMock: WireMock is a self-hosted API mocking tool with its own xCloud template. In a microcks vs wiremock choice, note that Microcks builds its mocks from imported specification files and reuses them for contract tests.
Smocker: Smocker is a self-hosted mock server with its own xCloud template. In a microcks vs smocker comparison, note that Microcks builds its mocks from imported API specifications and collections.
Stoplight Prism: Stoplight Prism is an OpenAPI mock and validation server you run yourself. Microcks, as deployed here, comes with a web interface, Keycloak sign-in and imports for OpenAPI, GraphQL, Postman and SoapUI.

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.

How much RAM does Microcks need?

The manifest asks for 2 CPU cores, 1536 MB of RAM and 10 GB of disk, and QA measured about 1.2 GB idle and 1.36 GB at peak across the six containers. The 6 GB Cloud VPS sold on this page leaves real headroom.

Is Microcks free and open source?

Yes. Microcks is Apache-2.0 licensed, per the LICENSE file at the 1.15.0 tag, so you pay nothing for licensing, only for the dedicated Cloud VPS xCloud provides, and your mocks and test results stay on your own volumes.

Can you run Microcks with Docker?

Yes, and this is Microcks Docker hosting prepared for you: the template runs the upstream Microcks 1.15.0 images with Keycloak, MongoDB and PostgreSQL, all pinned by immutable digest, behind two HTTPS domains, so it works as Microcks cloud hosting on your own VPS.

What is the difference between Microcks and WireMock?

Microcks turns OpenAPI, GraphQL, Postman and SoapUI assets into live mocks and reuses them for contract tests, with a web interface. WireMock has its own xCloud page, so compare the two against how you author mocks.

WireMock hosting

How do I sign in to Microcks?

Open the Microcks domain and sign in as admin with the password on the credentials card; Keycloak handles the sign-in and returns you to Microcks. The passwords are first-boot values, so rotate the admin password in Keycloak, not in the environment file.

Why does Microcks use two domains?

Microcks and Keycloak each get their own xCloud-managed HTTPS domain. The Keycloak domain is the token issuer and the Microcks domain is stored as the allowed redirect address, so choose both before first sign-in and keep them stable afterwards.

Are the Microcks mock endpoints public?

Mock endpoints are served on your Microcks domain and accept requests from any origin, which is the Microcks default. The management API returned 401 without a token in verification, so only the mocks are open. Restrict access in front if the mocks must stay private.

Does this Microcks template include gRPC mocks?

No. gRPC mocks and the async minion are not part of this template, even though upstream supports gRPC protobuf. AsyncAPI event mocks need that minion. Plan around OpenAPI, GraphQL, Postman and SoapUI assets here, and check your needs first.

How do I add teammates to Microcks?

Open the Keycloak sign-in domain at /admin/, add users to the microcks realm and give them the user, manager or admin role. Teammates then sign in through Keycloak on the Microcks domain. Test one new account before inviting everyone.

What should I back up on a Microcks server?

The microcks_mongo volume, with artifacts, mocks and test results, and the microcks_keycloak_db volume, with the Keycloak realm and users. Back up both before any upgrade, copy them off the server, keep the generated passwords private, and test a restore.

Backups in xCloud

How do I upgrade Microcks?

Updates are manual: the install stays on pinned release 1.15.0 until you adopt a newer template version. Back up both volumes first, read the Microcks release notes, then check sign-in and that an imported service still serves its mock.

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.
