The node runs asynchronously, so when a Pause node is reached and begins waiting for user interaction, other nodes that don’t depend on it can continue executing.

The default version includes a blinking continue button. The blinking functionality can be turned on or off, and both the blinking interval and color can be customized through the settings. Additionally, the node offers the following enhancements, all configurable via the settings:

cancel button: add a button to the node to interrupt the current run.
cancel and run button: add a button to the node to interrupt the current run and queue a new one.
force_pause toggle: when enabled, forces the node to execute even if the input has not changed.

Example workflows:

Single pause node: pause_single.json
Chained pause nodes: pause_chained.json
Parallel pause nodes: pause_parallel.json
Chained + parallel pause nodes: pause_chained_parallel.json

`Notify Audio`

Triggers an audio notification when executed. Available as both an output node and a passthrough node.

<div align="center"> <table> <tr> <td align="center"> <img src="https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/assets/audio_output.png" width="400"/><br> <b>Output node</b> </td> <td align="center"> <img src="https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/assets/audio_passthrough.png" width="400"/><br> <b>Passthrough node</b> </td> </tr> </table> </div>

A preset collection of 12 notification sounds is included.

To add a custom sound:

Copy your sound file into the web/audio folder.
Update the sounds object in web/js/sounds.js with the appropriate values.
Restart ComfyUI to apply the changes. Your custom sound will now appear in the dropdown list of available sounds.

Example workflows:

As an output node: audio_output.json
As a passthrough node: audio_passthrough.json

`Notify Toast`

Triggers a toast notification when executed. Available as both an output node and a passthrough node.

<div align="center"> <table> <tr> <td align="center"> <img src="https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/assets/toast_output.png" alt="Notify Toast Output node" width="400"><br> <b>Output node</b> </td> <td align="center"> <img src="https://github.com/vilanele/ComfyUI-AsyncPause/blob/main/assets/toast_passthrough.png" alt="Notify Toast Passthrough node" width="400"><br> <b>Passthrough node</b> </td> </tr> </table> </div>

Example workflows:

As an output node: toast_output.json
As a passthrough node: toast_passthrough.json

An example of a workflow combining the Pause node with notification nodes: notify_and_pause.json

Subgraphs

A common pattern is to create a subgraph containing a notification node before and/or after a Pause node to get notified when reaching and/or leaving a checkpoint.

Example workflow using subgraphs: pause_subgraphs.json

Related Custom Nodes

ComfyUI-pause includes a pause node, but it is not asynchronous and does not work properly with subgraphs.

To-Do

~~Make the Pause node blink while waiting for user interaction.~~ (done)
~~Add a cancel and run button.~~ (done)
Support multiple dynamically added input and output connections.
