“ComfyUI cloud” covers three different things: ComfyUI’s own hosted service, third-party hosting platforms, and a server you run yourself and reach through a browser. Hosted options bill by GPU time and get you started in minutes. A private ComfyUI server is a flat cost, keeps every photo and workflow on hardware only your company uses, and puts no cap on how much the team generates.
The question we hear most
“Can we just use ComfyUI in the cloud?” Yes, and sometimes you should. The people asking usually have three worries underneath the question: they do not want to set up a machine, they are not sure a GPU is worth buying, and they are not sure where their product photos end up. All three are fair. The answer depends on how often your team will generate, and on what the images are of.
What ComfyUI cloud means in 2026
ComfyUI itself is free and open source. What costs money is the GPU it runs on, and there are three ways to get one.
- ComfyUI’s own cloud service. The makers of ComfyUI host it on large data-centre GPUs with hundreds of models preinstalled. You buy credits and they are consumed while the GPU runs. It also offers partner models from commercial providers that you cannot run locally, and by default your inputs, outputs and workflows are private to your account.
- Third-party ComfyUI hosting platforms. Similar idea, often with an API for calling workflows from other software, and the same metered billing.
- Your own ComfyUI server. ComfyUI installed on a machine in your office or a rack, reached remotely by everyone on the team. The GPU is yours, the models are yours, and the meter is off.
So, is ComfyUI cloud free? The software is. The GPU time is metered on every hosted option, and that meter is what this comparison is about.
Where hosted ComfyUI wins
We will say this plainly because clients deserve it. A hosted service is the right choice when your team generates occasionally, when you need burst capacity for video models that want far more memory than a workstation card offers, or when the work depends on a proprietary partner model that only exists in the cloud. Setup is zero, and if usage stays light, the credits stay cheap.
Where a private ComfyUI server wins
The picture flips once a team generates every day.
- Flat cost, no cap. Ten images or ten thousand cost the same. We wrote about the per-seat and per-image trap in stop paying per user for AI image generation.
- Data stays in Singapore, on your hardware. Source product photos, unreleased packaging, client faces and campaign concepts never leave the building. Under the PDPA you remain responsible for that data wherever it goes, and the simplest way to meet that duty is to keep it on a machine only you use.
- Unlimited users. A hosted account is one balance. A private server is the whole company, with roles and an admin panel.
- Version control. ComfyUI updates every few days. On your own server you pin the version, the models and the custom nodes, so last month’s workflow still runs this month.
- The API is yours. ComfyUI exposes an API, which means automations can request images without a person clicking. A product listing pipeline or a WhatsApp agent can call the same server the designers use.
Running ComfyUI remotely for the whole team
Remote access is the part people overestimate. The server sits on your network or in a rack, ComfyUI runs as a service, and staff open it in a browser from their own laptops. Nobody installs anything.
For most of the team we put SecondBrain in front of it: a prompt library, curated styles and a generate button, with the ComfyUI graph doing the work underneath. The same server also feeds image generation inside MTChat, so a salesperson can ask for a quick visual in chat without ever opening the node editor. The designers keep full ComfyUI access for building the workflows everyone else runs.
The cost logic, without the price list
A metered service charges for every minute a GPU is busy. A private server charges once for the machine, or a flat monthly amount if you rent it from us, whatever the team does with it. The crossover comes sooner than most people expect: a marketing team that runs product variations, social visuals and a few campaign concepts each week keeps a GPU busy for hours, and hours are what the meter counts.
Two things the meter never shows: the cost of a designer waiting for credits to be approved, and the cost of explaining to a client where their photos went. Drop us an email for more information and we will size a server to your actual volume.
Where the cloud is still the right answer
If nobody on your side will own the machine, do not buy one. A server needs someone to keep it updated and backed up, and we can do that as part of the setup, but there has to be a named person on your team who cares. If you generate a handful of images a month, or your work lives on proprietary models you cannot download, stay hosted and we will tell you so.

FAQ
Can I use ComfyUI on the cloud?
Yes. ComfyUI's makers run a hosted version on data-centre GPUs, several third-party platforms host it too, and you can also run it on your own server and reach it through a browser. Hosted options bill by GPU time; a private server is a flat cost.
Is ComfyUI cloud free?
ComfyUI the software is free and open source. Every hosted option meters the GPU time, usually as credits that are consumed while a generation runs. Building and editing workflows is typically free; generating is what costs.
Can I run ComfyUI remotely for my team?
Yes. Install ComfyUI as a service on a server in your office or a rack, and staff open it in a browser from their own laptops. For non-technical users, a front end such as SecondBrain hides the node editor behind a prompt library and a generate button.
Does a private ComfyUI server need a data centre?
No. A single workstation-class machine with a 16GB GPU runs models such as Z-Image Turbo and Flux 2 Klein 4B for a whole team. Heavier image and video models benefit from a larger card, which is what our bigger server plan carries.
Is my data private on ComfyUI cloud?
On ComfyUI's own hosted service, inputs, outputs and workflows are private to your account by default. Privacy is still a matter of the provider's terms and where the servers sit. On a private server the photos and workflows never leave hardware only your company uses, which makes PDPA obligations simpler to meet.
Which is cheaper, ComfyUI cloud or a private server?
For occasional use, the cloud. For a team that generates daily, a private server, because the meter on hosted GPU time adds up quickly while a server costs the same whether it makes ten images or ten thousand. Drop us an email for more information and we will size it to your volume.
