Everything is a plugin

Fully Managed DeepSeek Harness Hosting

Run DeepSeek's open-source agent harness on a server we set up, secure and keep online. Every capability stays a plugin you can swap, and every run stays a session log you can replay.

  • Set up and running, reachable on your own domain
  • 24/7 expert support
  • No lock-in, cancel anytime

Agent = Model + Harness

The model is the soul. The harness is the body.

A harness is what lets an agent understand its environment, use tools and keep working in real-world settings. DeepSeek built theirs so that no part of it is welded shut.

  1. 01

    A kernel that mounts plugins

    The Cordis kernel manages plugin mounting, unmounting and dependencies. The agent's capabilities live in the plugins, not in the core.

  2. 02

    Every capability is a plugin

    Models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the UI are all plugins, wired together by Cordis services and events.

  3. 03

    Composed in configuration

    Select, swap or extend any capability in configuration, without changing the DeepSeek Harness source code or maintaining a fork.

Four Runtime Modes, and a Record of Every Run

Pick the mode that fits the job, then read back exactly what happened. Both halves are DeepSeek's design, not a layer we added.

  • Standard mode

    Full coding agent with file editing, shell, file and web search, skills, planning, goals, subagents and workflows.

  • Code mode

    Everything Standard has, with tools exposed through the Code Mode SDK so the model can combine multi-step operations in one TypeScript program.

  • Minimal mode

    A two-tool coding agent with persistent bash and a file editor, for benchmarking a model in a minimal environment.

  • Creator mode

    Built for authoring custom presets, with runtime inspection, in-memory plugin experiments and preset-authoring guidance.

  • Append-only session log

    System prompts, reasoning, tool calls and results, subagent scheduling and every context injection are all recorded.

  • Trajectory view

    Inspect what the model saw, by source, instead of guessing why it did what it did.

  • Resume, fork and replay

    All of them operate on the same event stream, so a run can be picked up, branched or re-run.

  • Search across runs

    The log is the interface. Find the run where it worked, and the one where it did not.

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.
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

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

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.

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.

What is DeepSeek Harness?

DeepSeek's open-source agent harness, published under the MIT licence. The model is the soul of an agent; the harness is what lets it understand its environment, use tools and keep working in real settings. It is built on the Cordis plugin system, so every capability including models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the UI is a plugin you can swap.

Is DeepSeek Harness ready for production?

DeepSeek describes it as a developer preview and says its core plugins and APIs will continue to evolve. We host it as it is rather than claiming otherwise. Managed hosting removes the server, the proxy, the certificate and the restarts, so the only moving part left is the one you chose to take on.

Do I need Docker or technical skills?

Not to get it running. xCloud provisions the server, installs the harness, configures the proxy and SSL and supervises the process. You do need to know what you want the agent to do, and to review what it does when it has a shell.

Why can I not just run it on my laptop?

You can, and it is the right way to try it. The gap opens when you want it working with the lid shut. It is also worth knowing that the harness serves its Web UI on 127.0.0.1 and the CLI refuses to bind wider, so remote access needs a reverse proxy on the same machine rather than an open firewall port.

Do I need a DeepSeek API key?

Only to use DeepSeek's models. The harness is provider-neutral: its catalogue covers Anthropic, OpenAI, Bedrock, Vertex and Azure, and a custom provider accepts any OpenAI-compatible endpoint, including a model running on your own server. xCloud never marks up your LLM costs.

Is DeepSeek Harness a one-click app on xCloud?

Not today. It is installed and configured on a Cloud VPS as a managed service rather than picked from the One-Click Apps list. If a one-click entry ships later, existing servers do not need to move.

Can I install my own plugins?

Yes, and it is the point of the project. Plugins are ordinary packages installed into a profile, DeepSeek maintains a discoverability topic for community ones, and you have a shell on your own server.

Can I resize the server later?

Yes. Move up or down the six Cloud VPS sizes as the workload changes; the harness and its session history come with it.

Can I cancel anytime?

Yes. There are no contracts. Because the harness runs on a fully managed xCloud server, on cancellation you are charged for server usage up to that date plus up to a 10% Stripe fee on the used amount.

Ready To Run a Harness You Can Actually Read?

Open source, MIT licensed, every capability a plugin, on a server we keep online for you.
