Introduction to ComfyOnline
ComfyOnline is a revolutionary cloud platform that allows users to run ComfyUI workflows without the need for expensive hardware or complex setup. Launched in 2024, it has quickly become the go-to solution for AI enthusiasts, developers, and creative professionals who want to leverage powerful AI models without technical barriers.
The platform eliminates common frustrations associated with running ComfyUI locally, such as GPU requirements, dependency installations, and VRAM limitations. Instead, ComfyOnline handles all the technical aspects in the cloud, allowing you to focus on creativity and results.
What sets ComfyOnline apart is its unique combination of accessibility and power. The platform supports a wide range of cutting-edge AI models for video generation (Kling, Runway, Luma, Hailuo, Veo), image creation (Recraft, Ideogram, Flux Pro Ultra), audio synthesis (ElevenLabs), and language processing (Claude, Gemini, GPT, Deepsek). This comprehensive support makes it suitable for virtually any AI-powered creative project.

How to use ComfyOnline in 2025 | Step by Step Guide
To begin using ComfyOnline, follow these steps:
Step 1: Explore the Dashboard
After purchasing credits, you'll have access to the ComfyOnline dashboard. Take some time to familiarize yourself with the interface:
- Explore: Browse community-shared workflows and applications
- Workspace: Access your saved and imported workflows
- My Apps: View applications you've created
- Credits: Monitor your credit balance and usage
- Settings: Configure your account preferences
The dashboard provides a clean, intuitive interface that makes navigation straightforward, even for beginners.
Step 2: Building and Importing Workflows
ComfyOnline offers two main approaches to creating workflows: building from scratch or importing existing ones.
Importing Existing Workflows
For beginners, importing existing workflows is the easiest way to start:
- Navigate to the "Explore" section
- Browse through the available workflows and templates
- When you find one you like, click on it to view details
- Look for the "Copy" button (usually labeled "Copy this workflow")
- Click "Copy" to add it to your workspace
- You'll receive a "Copy successful" confirmation
- Go to your "Workspace" tab to find the copied workflow
Each template in the Explore section is labeled as either an "app" or a "workflow." Apps provide a simplified interface for specific tasks, while workflows give you full access to the ComfyUI node editor.
Step 3: Creating a New Workflow
If you prefer to build from scratch:
- Go to the "Workspace" tab
- Click "Create New Workflow" or look for a "+" button
- This will open a blank ComfyUI canvas
- Start adding nodes and connections to build your workflow
The workflow editor in ComfyOnline is nearly identical to the standard ComfyUI interface, making it familiar for existing ComfyUI users.
Step 4: Running Your First Workflow
Once you have a workflow in your workspace, you're ready to run it:
- Click on the workflow in your workspace to open it
- If needed, upload your input images by clicking on the appropriate nodes
- Configure any parameters such as prompts, settings, or model choices
- When ready, click the "Run" button in the top-right corner
- The workflow will begin processing in the cloud
- You can monitor progress in real-time
- Results will appear in the output area when complete
The beauty of ComfyOnline is that all processing happens on powerful cloud GPUs (NVIDIA RTX 4090 24GB), so your computer doesn't need to handle any of the heavy lifting.
Step 5: Managing Workflow Outputs
After your workflow runs successfully:
- You can download the results directly to your device
- Save outputs to use as inputs for other workflows
- Share results with others via links
- Deploy the workflow as an API (more on this later)
Understanding the ComfyOnline's Credit System
ComfyOnline's credit system is designed to be transparent and cost-effective:
- Each workflow run consumes credits based on processing time
- The current rate is 0.62 credits per second of runtime
- You only pay for actual execution time, not for editing or idle time
- Different workflows consume different amounts of credits depending on complexity
- A typical image generation might take 30 seconds, costing around 18.6 credits
- A video generation could take 100 seconds, costing about 62 credits
With a $10 credit pack (12,000 credits), you could generate approximately:
- 600+ images (at 20 seconds per image)
- 40+ videos (at 300 credits per video)
The dashboard provides real-time tracking of your credit usage, making it easy to monitor costs.
How to Deploy APIs with One Click in ComfyOnline
One of ComfyOnline's most powerful features is the ability to instantly deploy any workflow as an API:
- Open the workflow you want to deploy
- Look for the "Deploy API" or "View API" button
- Click it to generate an API endpoint
- ComfyOnline will provide you with API documentation and access credentials
- You can now call this API from external applications, websites, or automation tools
This feature is particularly valuable for developers who want to integrate AI capabilities into their applications without managing infrastructure. The API deployment is handled entirely by ComfyOnline, including scaling to meet demand.
The API functionality enables numerous applications:
- Integrate AI image generation into web applications
- Build mobile apps with advanced AI features
- Create automation workflows with tools like Zapier or Make
- Develop custom solutions for business needs
- Embed AI video generation in content creation platforms
How to Use ComfyOnline to train LoRA Models in the Cloud
ComfyOnline also simplifies the process of training custom LoRA (Low-Rank Adaptation) models:
- Prepare your training dataset (images and prompts)
- Navigate to the LoRA training section
- Upload your dataset
- Select your base model (options include Flux, Hunyuan, Wan)
- Configure training parameters (learning rate, epochs, etc.)
- Start the training process
- Monitor progress in real-time
- Once complete, your custom LoRA model will be available to use in workflows
Training LoRA models typically requires significant GPU resources and technical knowledge, but ComfyOnline makes it accessible to everyone. This opens up possibilities for creating custom styles, characters, or effects that can be applied to your generations.
