# Comfy Cloud

> Use Comfy Cloud as an always-available managed deployment for running workflows via API

Comfy Cloud is the official managed ComfyUI platform. As a deployment target it is the zero-infrastructure option: there is no environment to build and no deployment to create. The endpoint is always there, models are pre-installed, and Comfy manages the GPUs.

You can think of it as a permanent serverless deployment. Where a [Serverless API](/development/serverless/overview) deployment serves one pinned environment that you build and release, Comfy Cloud serves a full, managed ComfyUI that is always on.

## What you get

* **A stable endpoint**: `https://cloud.comfy.org`, the default base URL for the [Comfy SDKs](/development/api-development/sdks).
* **Managed models**: a curated model library is pre-installed. You can also [import your own models](/cloud/import-models).
* **Managed GPUs**: no capacity planning, no regions, no worker bounds.
* **The Cloud editor**: build and test workflows in the browser, then run the same workflows via API.

## Requirements

* A Comfy Cloud account. See the [Comfy Cloud introduction](/get_started/cloud) if you are new to it.
* An [API key](/development/api-development/getting-an-api-key).

<Note>
  API access requires a paid Comfy Cloud subscription. The free tier does not include it, and your tier determines how many jobs you can run at once.
</Note>

## Run workflows against it

Comfy Cloud works with the SDKs out of the box. Create an API key and pass it to the client; the base URL defaults to Comfy Cloud, so there is nothing to configure.

<CodeGroup>
  ```python Python theme={null}
  from comfy_sdk import Comfy

  client = Comfy(api_key="comfyui-...")
  ```

  ```typescript TypeScript theme={null}
  import { Comfy } from "@comfyorg/sdk";

  const client = new Comfy({ apiKey: "comfyui-..." });
  ```
</CodeGroup>

See [Running Workflows](/development/run-workflows/overview) for the full picture, or go straight to the [SDK guide](/development/api-development/sdks).

The deprecated [v1 Cloud API](/development/cloud/overview) also runs against Comfy Cloud. Use it only for existing integrations or for Cloud capabilities that [Comfy API v2](/api-reference/v2/overview) does not expose yet.
