ComfyUI on a rented GPU
How much memory ComfyUI needs depends on the model in your graph: SD 1.5 runs on 6 GB, Flux.1 dev needs about 24 GB, video models 48 GB and more. An empty ComfyUI installs itself and opens in your browser. If you need a specific model, a ready-made app is faster: Flux, SDXL, Qwen-Image or Wan 2.2 download without your help.

How to run ComfyUI in 3 steps
- Sign up and top up. Create an account and top up from €10. To launch, your balance must cover at least one hour of the chosen machine; after that you pay by the minute.
- Choose a GPU. Memory for each version is in the table above, and the lightest one runs from 6 GB. The button on this page selects the cheapest option with the ComfyUI template.
- Work in your browser. The server is ready in 2–5 minutes and a button that opens ComfyUI appears in the dashboard. Download the models you need with the commands below.
Finished? Stop the server in the dashboard and billing stops. Save and stop keeps /workspace for €0.03 per GB per month, and it comes back on your next server automatically.
Installation
git clone https://github.com/comfyanonymous/ComfyUI && cd ComfyUI
pip install -r requirements.txt
python main.py --listen 0.0.0.0 --port 8188
What people run ComfyUI for
01
Your own graphs and nodes
Bring a workflow as JSON and download the models and custom nodes it needs.
02
Any image model
SD 1.5, SDXL, Flux, Qwen-Image and thousands of community checkpoints in one interface.
03
Video
Wan 2.2 from the built-in templates: Workflow → Browse Templates → Video.
04
Generation through the API
ComfyUI accepts a graph over HTTP, so a script can queue hundreds of images.
Tips before you launch
- VRAMfarm has a ready-made app: ComfyUI opens with the Open ComfyUI button in the dashboard.
- ComfyUI-Manager is not preinstalled: add custom nodes with git clone into custom_nodes, or install the Manager yourself.
- Save your models, nodes and graphs with the folder when you stop, so you don’t rebuild the environment every time.
Other ready-made apps
Each app installs its interface and model on its own. You only pay for GPU time.

Frequently asked questions
Can I use the interface from my browser?
Yes. After launch, an Open ComfyUI button appears in the dashboard.
How is an empty ComfyUI different from a ready-made app?
An empty ComfyUI only has the SD 1.5 base model; you download everything else yourself. Ready-made apps download Flux, SDXL, Qwen-Image or Wan 2.2 straight away.
How long does a launch take?
The server is usually ready in 2–5 minutes, then SSH and Jupyter are available. Downloading the model depends on its size and is billed as normal server time.
What happens to my models and results after I stop?
When you stop, click Save and stop: the /workspace folder with your models, LoRAs and results goes to storage for €0.03 per GB per month and comes back on your next server automatically. If you stop without saving, the disk is deleted.
How is it billed?
By the minute from your balance in euros. Top up from €10; to launch, your balance must cover at least one hour of the chosen machine. Stop the server and billing stops.
