Comfy Cloud Quickstart

Comfy Cloud is a fully managed, always-available ComfyUI environment. Build workflows in the browser or run them through the SDK. There is no Build or deployment to create.

New to Comfy Cloud? Start with the Comfy Cloud introduction. This quickstart shows how to run workflows from an app.

Quickstart

Requires a paid subscription, an API key, and an API-format workflow. The Comfy SDKs target Cloud by default.

Create an API key

Create an API key at platform.comfy.org. See Getting an API Key for details.

Install the SDK

pip install comfy-sdk

npm i @comfyorg/sdk

Export a workflow in API format

In the Cloud editor, save your tested workflow as workflow_api.json with File → Export Workflow (API). See Workflow API Format.

Run it

from comfy_sdk import Comfy

client = Comfy(api_key="comfyui-...")  # Comfy Cloud is the default target

wf = client.workflows.from_file("workflow_api.json")

job = client.run(wf)
for output in job.get_outputs("9"):
    output.to_file(output.name)

import { Comfy } from "@comfyorg/sdk";

const client = new Comfy({ apiKey: "comfyui-..." }); // Comfy Cloud is the default target

const wf = await client.workflows.fromFile("workflow_api.json");

const job = await client.run(wf);
await job.getOutputs("9")[0].toFile("out.png");

"9" is the output node ID. See the SDK guide for inputs, progress, and error handling.

The same SDK code can target Comfy API deployments and self-hosted ComfyUI. See Running Workflows.
