Show HN: Use your domain as its own sale page

Hi! If someone by chance collects/flips domains here, I built a small tool that lets you turn any domain you own into a simple for-sale page to get leads directly in your preferred contact (messenger, whatsapp, discord, email etc.).

You verify the domain once via redirect. After that, you can:

- Keep the redirect and use the generated sale page - Remove the redirect and still keep the page live - Share the page link in auctions or outbound emails - Use it as a clean reference page for buyers

So even if you list your domain on marketplaces, this works as an independent page you control. Buyers can contact you directly and you're free to choose your own escrow.

It also includes valuation estimates and optional portfolio page if you manage multiple names.

Example page: https://d.omain.co/d/startup.broker

Curious if this feels genuinely useful as a supplemental channel, or redundant in practice
