ComfyUI (Local)

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

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

Troubleshooting

Local Server Not Working

Try the Test Connection button to diagnose. "Blocked by CORS" 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.
