What is Langflow?

Langflow is an open-source, low-code visual builder for AI agents and retrieval-augmented generation (RAG) workflows. You assemble a flow on a canvas, run it from the built-in playground, and then call it over a REST API or an MCP endpoint. It is licensed under MIT.

This template runs Langflow 1.12.6 with a private PostgreSQL database, so your flows, users and stored variables live in a database rather than a local file.

From Sign-Up to Your First Flow In Just 3 Easy Steps

A Langflow stack normally means an app container, a PostgreSQL database, a generated admin password, volumes, a domain and a certificate before the first flow. This is the same result without assembling any of it.

  1. Step 01

    Sign Up

    Create your xCloud account and pick Langflow from the OneClick catalog. Choose your domain and target server — there are no extra fields to fill in.

  2. Step 02

    We Deploy It For You

    One click. We bring up the official Langflow image and a private PostgreSQL 16 database with no host ports, mount the langflow_data and langflow_db volumes, generate the admin password and publish it over HTTPS on your domain.

  3. Step 03

    Sign In And Build A Flow

    Wait two to three minutes for the first start, open your HTTPS Langflow URL and sign in as admin with the generated password. Then add your model provider keys as global variables and build your first flow.

Everything Langflow Does, On Your Own Server

Langflow runs in full here: a visual flow builder, playground and API on your own domain, backed by a database you own.

  • A Visual Canvas For Agents And RAG

    Design AI agents and retrieval-augmented workflows by assembling flows on a canvas instead of writing the orchestration by hand.

  • Test In The Playground

    Run a flow in the built-in playground to see how it behaves before you expose it to anything else.

  • REST API And MCP Endpoint

    Call your flows over the REST API or the MCP endpoint, both served on the same HTTPS domain; API calls use a key created in Settings.

  • Login Required, Sign-Up Off

    Every visitor must sign in and public sign-up is disabled; admins add users from inside Langflow.

  • Flows Stored In PostgreSQL

    Flows, users and variables are kept in a private PostgreSQL 16 database on the langflow_db volume rather than a local file database.

  • State That Survives A Restart

    Flows, users and stored variables were still present after an xCloud Restart of both containers in QA.

Everything You Need To Run Your AI Flow Builder 24/7

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

  • Langflow 1.12.6 deployed instantly
  • Official image pinned by digest
  • Admin password generated for you
  • Private PostgreSQL, no host ports
  • Free SSL certificate
  • Server backups and snapshots
  • Server security updates included
  • 30+ server locations
  • Unused balance refunded

What You Can Do With Langflow

  • Prototype an AI agent without writing the plumbing

    Wire a model, tools and prompts together on a canvas and try the result in the playground before anyone else can reach it.

  • Build a RAG workflow over your own documents

    Design the retrieval-augmented flow visually, then call it from your own application over the REST API.

  • Expose a flow to other tools over MCP

    The MCP endpoint is served on the same domain as the interface, so a flow you build can be called by MCP-aware clients.

  • Keep flows and model keys behind a login

    Sign-in is required and public sign-up is off, so your flows and the provider keys you store as global variables are not open to visitors.

Langflow vs Alternatives

n8n
A workflow automation tool built around triggers and app integrations; Langflow is centred on designing AI agent and RAG flows and calling them over an API.
Flowise
Another visual builder for LLM flows; Langflow pairs its canvas with a playground and exposes flows over a REST API and an MCP endpoint.
Dify
An LLM application platform; this Langflow install is a canvas-and-flow builder that runs as one app container plus a private PostgreSQL database.
Writing the flow in code
Building agents directly in Python gives full control; Langflow gives you the same kind of pipeline on a canvas with a playground, while still allowing custom Python components.

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.

Frequently Asked Questions

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

How do I sign in?

Use username admin and the generated password shown in the protected installation credentials. The first start takes two to three minutes, so wait a moment and refresh if you see a gateway error.

Can visitors register?

No. Sign-up is disabled; admins add users from inside Langflow. Flows can run custom Python code on the server, so create accounts only for people you trust.

What runs alongside Langflow?

A private PostgreSQL 16 container with no host ports. It stores your flows, users and variables.

Where do I put OpenAI or Anthropic keys?

Inside Langflow as global variables, not in the environment file.

Can I call my flows from other applications?

Yes. The REST API and the MCP endpoint are served on the same domain as the interface. API calls need a Langflow API key created from the Settings page.

How do I change the admin password?

Change it from the profile settings after first sign-in. The generated password is only read on the first start, so editing it in the environment file later does not change the existing login.

What should I back up?

Both volumes: langflow_data (the generated secret key, logs and file storage) and langflow_db (the database with flows, users and variables). The secret key encrypts stored credentials and must not change.

Backups in xCloud

Is there an upload size limit?

The site accepts large uploads, but behind a Cloudflare-proxied domain a single upload is limited to about 100 MB.

Does xCloud automatically back up or update Langflow?

No. The template pins Langflow 1.12.6 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Back up first, read the Langflow release notes, then bump the image 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 2 CPU cores, 2048 MB of RAM and 10 GB of disk; measured use in QA was about 1.2 GiB for Langflow plus about 40 MiB for the database. This page sells the 6 GB tier as the entry rung, with real headroom above that baseline.

What survives a restart?

Flows, users and stored variables — they were still present after an xCloud Restart of both containers in QA, because they live on persistent named volumes.

Is xCloud officially partnered with Langflow?

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