The library
The library is the panel on the left. It shows what your ComfyUI has and what this project holds, in three tabs: Nodes, Models and Subgraphs. Everything in it comes from reading your ComfyUI; reading changes nothing there.
The tabs
| Tab | What it lists | Page |
|---|---|---|
| Nodes | every node class of your ComfyUI, grouped by category, and the four editor nodes Note, Markdown Note, Reroute and Primitive | Nodes in the library |
| Models | your model files, with their kind and family | Models in the library |
| Subgraphs | the subgraphs of this project | Subgraphs in the library |
How to open and fold it
- Collapse library (the icon at the top right of the panel), View ▸ Library or
Ctrl+Bfolds it to a strip of icons. - In the strip, Expand library opens it again; the icons of the three tabs open it on that tab.
- In a window narrower than 1180 pixels the library starts folded.
When it is empty
- Before your ComfyUI is read: "Your ComfyUI is not read yet. The nodes of your ComfyUI appear here once the app reads it. Reading changes nothing in ComfyUI." with a button to read it.
- Without an address: "The nodes of your ComfyUI appear here. Tell the app the address of your ComfyUI first; then it reads which nodes you have." with Open connection settings. The address is the one you open ComfyUI at in the browser; an MCP server is optional. See Connecting.
- "The library could not be read." if the app's own data could not be read.
