Metadata Protection

Rigs protects your workflow IP by stripping workflow JSON from output PNGs by default.

Why It Matters

ComfyUI embeds prompt + workflow JSON directly inside PNG metadata. Anyone who downloads your image can extract it and recreate your full workflow.

Rigs removes those chunks when a job completes, so consumers can’t recover your workflow graph.

How It Works

When a PNG output is received, Rigs removes all non‑essential PNG chunks, including tEXt, iTXt, and zTXt. This keeps the image intact while removing:

  • Workflow JSON
  • Prompt text
  • Embedded node parameters

Provider Control

On the Network tab, each workflow has a Protected / Exposed toggle:

  • Protected (default): workflow JSON is stripped
  • Exposed: workflow JSON remains embedded

Disabling protection will show a warning confirmation.

CLI Behavior

The provider client applies the same logic when returning outputs to the network gateway. You can always re‑enable protection by toggling the workflow setting.
