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 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.
  • Managed models: a curated model library is pre-installed. You can also import your own 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

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.

​
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.
See Running Workflows for the full picture, or go straight to the SDK guide. The deprecated v1 Cloud API also runs against Comfy Cloud. Use it only for existing integrations or for Cloud capabilities that Comfy API v2 does not expose yet.
