# How to add custom nodes to ComfyUI

Extend ComfyUI with custom nodes: install a node pack, restart, and confirm it appears in the graph.

## Facts (2026-10-17)

- **Price:** Free
- **Platform:** Windows, macOS, Linux

## Adding a node pack

Install the pack, restart ComfyUI, then search the node menu for the new nodes. Remove a pack the same way if a workflow breaks.

## FAQ

### Why do nodes show as missing?

The workflow needs a pack that is not installed yet. Install the named pack and reload the workflow.
