RunComfy

RunComfy is a cloud platform that runs ComfyUI, the node-based interface widely used for Stable Diffusion and related image and video models, without requiring users to install anything locally or own a capable GPU. The platform ships with more than 200 ready-to-run workflow templates, and an auto-setup process handles the dependencies, custom nodes, and model files that ComfyUI workflows typically need before they can run. Users can pull models directly into their workspace from Civitai, Hugging Face, or Google Drive, which the platform says is far faster than uploading them manually, and can choose from several GPU tiers ranging from 16GB up to 141GB of memory depending on the size of the model being run. Finished environments can be saved to the cloud and shared with others, so a workflow built once can be reproduced exactly rather than reassembled from scratch. A ComfyUI-Manager component lets users add custom nodes without hitting configuration limits. Beyond interactive use, RunComfy offers a serverless API that turns a saved workflow into a production endpoint with autoscaling and pay-as-you-go billing, which is aimed at developers who want to embed ComfyUI-based generation into their own applications rather than running it manually through the browser interface.
