Run ComfyUI workflows and build AI apps without managing GPUs
What is ComfyOnline?
ComfyOnline is an online platform for running ComfyUI workflows and deploying APIs from them. It is aimed at people who want to build AI applications with ComfyUI without managing their own GPU setup or infrastructure.
The product emphasizes a managed workflow runtime: it handles installation and model downloads, charges for runtime rather than idle usage, and can generate APIs so workflows can be integrated into downstream applications. The site also presents examples and templates across image generation, video generation, audio, and LLM use cases.
What can ComfyOnline do?
Managed setup
Skip dependency setup and model downloads so you can focus on building workflows rather than configuring the runtime.
API generation
Generate APIs from workflows with one click, which lets you turn a ComfyUI workflow into a callable backend for an app.
Runtime-based billing
Pay only while workflows are running, with no idle GPU charge while you are editing or not actively using the runtime.
Auto-scaling runtime
Scale automatically when traffic increases, so the platform can handle larger demand without manual infrastructure changes.
Multi-modal workflow support
Work with supported AI services and custom nodes spanning video, image, audio, and LLM workflows.
Use Cases
“Interactive workflow creation”
Use the web workspace to build and iterate on ComfyUI workflows without renting and configuring a separate GPU instance.
“AI app backend creation”
Turn a workflow into an API so another app or service can trigger it without manually opening the ComfyUI editor.
“Workflow discovery and prototyping”
Explore image, video, audio, and language-model workflow examples to understand what kinds of outputs the platform supports.
“Cost-conscious experimentation”
Use the runtime-based model when you want to avoid paying for idle compute while you are editing or waiting between runs.
“Template-led experimentation”
Start with preset examples and templates when you want to adapt an existing ComfyUI workflow instead of building everything from scratch.
