Cloud ComfyUI platform to run workflows and build AI apps
Run, import, and share ComfyUI workflows in the cloud without local GPU hardware.
Publish a workflow as a single-click AI app that anyone can run with simple inputs.
Use hosted image and video models, including self-developed upscaling and enhancement tools, from one dashboard.
Integrate generation into your product via workflow, model, LLM, and app APIs.
Turn rough sketches into refined AI images
Use the built-in canvas to draw your idea, or upload an existing sketch, then submit it with a text prompt. The service renders a refined image that follows both the shapes you drew and the description you typed.
Iterate by changing the prompt while keeping the same drawing, so a single sketch can branch into several visual directions — different colours, styles, materials or lighting on the same composition.
Images are returned in a high-quality format and paid plans prioritise generation speed, so you are not waiting on long queues when you are working through a set of ideas.
A public Explore gallery shows what other users have produced, which is a quick way to understand the range of styles the model handles before you commit to a credit purchase.
