ComfyUI Node Reference
This documentation covers all 1110 nodes across 11 packages supported by cmfy.cloud.
Packages
Package Categories and Billing
Nodes are organized into different packages based on their source and functionality:
Local Processing Nodes
Most packages contain nodes that run entirely on the GPU allocated to your job. These include:
- ComfyUI Core - Built-in nodes for image generation, sampling, and model loading
- ComfyUI Extras - Additional built-in utilities and specialized nodes
- Custom node packs - Community-contributed nodes that extend ComfyUI functionality
For these nodes, you are billed only for cmfy.cloud GPU runtime.
API Nodes (External Services)
The ComfyUI API Nodes package provides access to external AI services through comfy.org's credential system. When using these nodes:
Dual Billing
- comfy.org bills you for the external API usage (OpenAI, Runway, Stability, Kling, etc.)
- cmfy.cloud bills you for GPU runtime while the workflow executes
Ensure you have appropriate credits in both systems before using API nodes.
Finding Nodes
Use the search bar in the navigation to find specific nodes by name. Nodes are organized by package, and each package page lists nodes grouped by category.
