Sim Hosting Live In 5 Minutes

Deploy Sim hosting and build, run and schedule AI agent workflows on your own server. xCloud runs Sim v0.9.14 with PostgreSQL and pgvector, Redis, the realtime socket and the scheduler on a private network, generates the secrets, keeps accounts, workflows and uploads on persistent volumes and serves everything over HTTPS on one domain.

What is Sim?

Sim is an open-source workspace to build, deploy and manage AI agents and workflows. Its upstream README describes connecting 1,000+ integrations and every major LLM, building agents visually, conversationally or with code, ingesting files and knowledge bases, and monitoring runs, logs and schedules.

The self-hosted deployment runs the published Sim images with Docker Compose. Sim is released under the Apache-2.0 licence; its Enterprise features are covered by a separate licence and are not part of this template.

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

A Sim install normally means a web app, a realtime server, a scheduler, a vector-enabled database, Redis, a set of secrets, a domain and a certificate before the first workflow exists. This is the same result without assembling any of it.

  1. Step 01

    Sign Up

    Create your xCloud account and pick Sim from the OneClick catalog. Choose your domain and server. There are no extra fields; xCloud generates the credentials and shows the database password and encryption key in the protected installation credentials.

  2. Step 02

    We Deploy It For You

    One click. We bring up the Sim app, realtime server and scheduler with PostgreSQL 17 and pgvector and Redis on the private network, run the migrations, keep data on the postgres_data and uploads_data volumes and serve the app, API and socket over HTTPS on one domain.

  3. Step 03

    Create Your Account And Add A Model Key

    Allow about five minutes for the first start to pull images and run migrations. Open the HTTPS URL, create your account from the sign-up page, add your model provider keys under Settings, then set DISABLE_REGISTRATION=true to close sign-up.

Everything Sim Does, On Your Own Server

Sim runs in full here: a visual agent workflow builder with its realtime and scheduling services, on a domain and a server you control.

  • Visual Workflow Canvas

    Build agent workflows on a visual canvas from agent, tool and logic blocks.

  • Flexible Triggers

    Start workflows from a schedule, a webhook, an API call or a deployed chat.

  • Knowledge Bases

    Upload documents and search them by vector similarity, backed by the pgvector-enabled PostgreSQL in the same instance.

  • Live Collaboration

    Work on the same canvas together through the realtime socket, served on the same HTTPS domain as the app.

  • Integrations And Models

    Upstream lists 1,000+ integrations and every major LLM; you bring your own provider keys in Settings.

  • Runs And Logs

    Monitor runs, logs, schedules and workflow activity; execution logs are kept in your own PostgreSQL database.

Everything You Need To Run Your AI Workflows 24/7

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

  • Sim v0.9.14 deployed instantly
  • PostgreSQL with pgvector included
  • Secrets generated for you
  • Persistent database and uploads
  • Free SSL certificate
  • Server backups and snapshots
  • Server security updates included
  • 30+ server locations
  • Unused balance refunded

What You Can Do With Sim

  • Automate a task with an AI agent

    Chain agent, tool and logic blocks on the canvas so a model does the repetitive work between your systems.

  • Run workflows on a schedule or a webhook

    Trigger the same workflow from a timer, an incoming webhook or an API call, without keeping a laptop open.

  • Answer questions from your own documents

    Upload documents to a knowledge base and have workflows search them with vector search.

  • Keep agent data on your own server

    Store accounts, workflows, execution logs and uploads in your own PostgreSQL database and upload folder.

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.

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 there a default admin login?

No. Sim has no pre-created admin. Create your own account from the sign-up page, then close sign-up by setting DISABLE_REGISTRATION=true in Environment and redeploying.

Does Sim need an AI provider key to start?

No. Add model provider keys inside Sim under Settings whenever you are ready. Sim Chat is optional and needs its own COPILOT_API_KEY from sim.ai; without one, set NEXT_PUBLIC_CHAT_DISABLED=true to hide the Chat module.

What runs alongside the web app?

A realtime server for live canvas collaboration, a scheduler for scheduled workflows and polling triggers, PostgreSQL with pgvector, and Redis. All of them run privately inside the site, with no host ports.

Who can run code on my server?

Anyone with an account can create workflows that run code and make outgoing HTTP requests from the server. Keep sign-up closed once your team is in.

What should I back up?

Both named volumes, postgres_data (accounts, workflows, knowledge bases, execution logs) and uploads_data (uploaded files), plus the generated environment values. ENCRYPTION_KEY and API_ENCRYPTION_KEY must not change after install, or stored credentials and API keys become unreadable.

Backups in xCloud

When should I change BETTER_AUTH_SECRET?

Only if you want to sign every user out.

What survives a restart?

Your accounts, workflows, knowledge bases, uploaded files and settings, because they sit on named volumes. After a simultaneous restart of all containers, the realtime service logged one Redis socket error and recovered without further errors.

Does xCloud automatically back up or update Sim?

No. The template pins Sim v0.9.14 by immutable digest; new installations use the pinned release and existing sites are not automatically upgraded. To upgrade, 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 16 GB?

The template's baseline asks for 2 CPU cores, 12 GB of RAM and 20 GB of disk; measured idle use in QA was about 1.75 GiB across all containers. Because the manifest floor is 12 GB, this page sells the 16 GB tier as the entry rung.

Is xCloud officially partnered with Sim?

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