ComfyUI-Terminal-Log — Display Terminal Output Directly in ComfyUI

Description and use

A custom ComfyUI node displays terminal output directly in the UI, eliminating the need to switch between ComfyUI and a separate terminal.

Problem

Long or resource-intensive ComfyUI processes require constant monitoring of console output, but switching between ComfyUI and a separate terminal is inconvenient.

Outcome

The custom node integrates terminal output into ComfyUI, improving monitoring efficiency and reducing context switching.

Workflow

• Create a custom node in ComfyUI that captures stdout and stderr streams.
• Configure the node to display captured output in a scrollable text area.
• Adjust font size and enable optional ANSI color handling as needed.
• Insert the node into the workflow where long-running processes are executed.
• Run the workflow and observe live terminal output directly within the ComfyUI workspace.

Evidence

I built a small ComfyUI custom node that displays terminal and log output directly inside the ComfyUI interface.

Source

The idea is simple: when running long or resource-intensive processes, you can monitor the console output without constantly switching between ComfyUI and a separate terminal window.
