From local workflow to production API in 3 steps

cmfy.cloud runs your ComfyUI workflows exactly as you built them. No rewrites, no new SDKs, no deployment hassle.

Use your existing workflows

Export from ComfyUI, POST to our API. Same JSON format you already know.

Production-ready instantly

No servers to provision, no dependencies to install, no infrastructure to manage.

Pay only for compute time

No cold start charges. You pay for generation, not for models loading.

Scales automatically

From 1 to 10,000 requests. We handle load balancing and queuing.

Here's all it takes

1

Export your workflow JSON from ComfyUI

Click "Save (API Format)" — that's the exact format we use
2

Use public URLs for models and inputs

Point to HuggingFace, CivitAI, S3, or any publicly accessible URL
3

POST to our /prompt endpoint

Get back your generated images. That's it — you're in production.

How It Works

Three steps. No configuration. No learning curve.

Export

Export your workflow JSON from ComfyUI. Use the built-in "Save (API Format)" option.

Configure

Use public URLs for models and inputs. Works with HuggingFace, CivitAI, S3, or any public URL.

POST

Send to our /prompt endpoint. Get results via webhook or poll for completion.
