RunDiffusion makes it easy to run multiple OpenSource Application sessions at the same time. This is perfect for testing different workflows, comparing results, or running separate projects in parallel.


Why do I need multiple sessions?

Launching multiple sessions is especially useful when working on projects that require significant processing time. For example:

  • Running long Deforum animations or audio reactive videos in ComfyUI
  • Performing high resolution upscaling which may take several minutes
  • Creating text to video or image to video generations
  • Using video to video generation with ControlNet or AnimateDiff in ComfyUI
  • Testing multiple workflows side by side in ComfyUI

These tasks can take time to render. Running multiple sessions lets you stay productive while waiting for results


Option 1: Launch from the Loading Screen

If you know that you will need multiple sessions you can launch several sessions at the same time.
