Run ComfyUI on a cloud GPU, in 30 seconds
Node-based image and video workflows with ComfyUI-Manager pre-installed. ComfyUI is the node-based workflow engine for Stable Diffusion, SDXL, Flux and today's video models. The template ships with ComfyUI-Manager for one-click custom nodes, exposes the UI on a TLS-terminated port and mounts a model folder you can put on a volume. Every workflow also exports as JSON and runs headless through the API. From $0.052/hr on an interruptible RTX 3090.
Template is free
You pay the GPU price only: ComfyUI on a RTX 3090 is $0.104/hr on-demand, $0.052/hr interruptible, billed per second.
Volumes for state
Models, datasets and outputs live on a $0.08/GB/mo volume; the instance stays disposable.
Private by default
Dedicated GPU, encrypted disk, crypto payments, no KYC, no stored IPs — Jupyter and SSH behind your own credentials.
Best GPUs for ComfyUI
Three price points that run this template well — Good, Better, Best. Every model in the catalogue works; these are the value picks.
| Tier | GPU | VRAM | On-demand | Interruptible | Why this card | Action |
|---|---|---|---|---|---|---|
| Good | RTX 3090 | 24 GB | $0.104 | $0.052 | 24 GB at the lowest price — the batch-farm workhorse for SDXL. | Deploy |
| Better | RTX 4090 | 24 GB | $0.262 | $0.131 | The community default: Flux dev images in about 2 seconds each. | Deploy |
| Best | RTX 5090 | 32 GB | $0.318 | $0.159 | 32 GB GDDR7 for full-precision Flux, video nodes and heavy upscale chains. | Deploy |

Deploy ComfyUI from the console, CLI or API
Pick the template in the console deploy bar, or script it:
- Console — filter by GPU, choose ComfyUI in the template picker, set disk and env, deploy.
- CLI — pip install powergpu, then the command on the right. CLI reference.
- API — POST /v1/instances with "template": "comfyui". REST reference.
- Own image — any OCI reference works too; we inject the NVIDIA runtime. Template docs.

ComfyUI on a cloud GPU: FAQ
Environment variables, ports and custom images are covered in the template docs.
How much does it cost to run ComfyUI on a cloud GPU?
Only the GPU price — the template is free. From $0.052/hr on an interruptible RTX 3090, $0.104/hr on-demand on a RTX 3090. Billing is per second, so an hour of tinkering costs an hour, not a day. Storage is $0.08/GB/month.
How long does ComfyUI take to start?
About 30 seconds from the deploy click: the image is pre-cached on hosts, ports are mapped and TLS is terminated for you. Restarting a stopped instance is faster, and your disk is exactly as you left it.
Can I keep my models and outputs between sessions?
Yes — attach a volume at deploy. Everything on the volume survives instance destruction and mounts on the next instance in the region in seconds, at $0.08/GB/month. The instance disk itself survives stop/start but not destroy.
Where do I put my checkpoints and LoRAs?
Mount a volume on /workspace/ComfyUI/models. Checkpoints, LoRAs, VAEs and ControlNets persist across instances and load in seconds from NVMe instead of downloading every time.
