Demo URL Field
A demo URL lets buyers inspect the product before purchase.
Use it when the product has a visual interface, hosted preview, sandbox, documentation demo, or public example workflow.
A good demo reduces uncertainty. Buyers can confirm the layout, behavior, setup assumptions, and fit before they pay.
Do not link to a generic homepage unless it shows the product clearly. The demo should help someone decide whether this exact listing is right for them.
If the product needs setup instructions, pair the demo with a Docs URL.
