ComfyUI (Local)

Connect to a local ComfyUI instance to perform highly customizable node-based image generation.

  • Setup Requirements:
    • The ComfyUI server must be running. For example, you need to enable CORS by starting the server with the --enable-cors-header flag. Load your desired workflow in ComfyUI and click "Save (API Format)". Paste the resulting JSON into the ComfyUI Workflow (JSON) field of this app.
  • Workflow Placeholders: This app automatically replaces the following placeholders within the workflow JSON:
    • The string ##prompt## is replaced with the AI's positive image prompt.
    • The string ##negative_prompt## is replaced with the AI's negative image prompt.
    • The number 1234567890 is replaced with a random seed for each generation. Please ensure this number exists in the seed input of the KSampler.

Troubleshooting​

Local server is not working​

Check the browser's developer console (F12) for "CORS" or "network" errors. This is the most common issue. Ensure the server is started with the correct flag (e.g., --enable-cors-header for ComfyUI) and that the endpoint URL in this app is correct.
