One search. Every place that matters.

Stop refreshing ten tabs.

  1. 1

    Save what you hunt for

    "tolkien hobbit first edition", "bob dylan tarantula", "harry potter signed". As many searches as you like.

  2. 2

    It checks on a schedule

    Every 10 to 60 minutes, quietly from your menu bar, across every marketplace and auction house you switch on.

  3. 3

    You hear about new listings only

    One notification per search with what just appeared. Click it and you're on the listing, before anyone else.

New means new.

The first check remembers everything already listed. After that, only fresh listings get the green NEW badge, and the same copy listed on two eBay sites only counts once.

Auction lots from the-saleroom with estimates and sale dates

Auctions included.

Catawiki, Heritage, Invaluable and the-saleroom sit next to the marketplaces, with estimates, current bids and closing times, so a first edition going under the hammer doesn't slip past you.

Lives on your desk, not in a tab.

A native app for Mac and Windows that keeps checking from the menu bar after you close the window. Light and dark, like the rest of your computer.

Questions

Where does ShelfProud run? +

On your own computer, as a small desktop app for Mac and Windows. It keeps working from the menu bar when you close the window, and checks your searches on a schedule you choose (every 10 to 60 minutes).

How does it know what is new? +

The first time a search runs, everything already listed is remembered as seen. From then on you only hear about listings that appear afterwards, one notification per search, never a flood.

Which sites can it watch? +

eBay (US, UK and Germany), Etsy, AbeBooks, Vinted, PangoBooks, Catawiki, Heritage Auctions, Invaluable and the-saleroom. You can switch any of them off.

How do I get an access key? +

ShelfProud is in a free, invite-only beta. The app asks for an access key the first time you open it. To get one, email [email protected] and tell us whether you use a Mac or Windows; you can also ask the person who invited you.

Mac says the app can’t be opened. What do I do? +

Open the downloaded file and drag ShelfProud into Applications. The first time you open it, macOS blocks it because it isn’t from the App Store: go to System Settings → Privacy & Security, scroll down and click “Open Anyway”. You only need to do this once.

Windows shows “Windows protected your PC”. +

Click “More info” and then “Run anyway”. It appears because ShelfProud is a new, independent app.

Do I need an account on those sites? +

No. ShelfProud searches the same public listings you would see in your browser, and opens the original listing when you click it. Buying happens on the marketplace, as usual.
