Buyers bid harder when they can see the board.

Overlay Deck puts a live buyers leaderboard on your stream. Every sale updates it instantly, so your chat can watch the race for number one.

Built for Whatnot. Runs on macOS and Windows through OBS, signed and notarized so it installs without warnings.

Recorded live, mid-show

Seven overlays, driven by your live sales

Each one is a browser source you drop into OBS once. They read your real stream data, so nothing is typed in by hand.

A buyers leaderboard reordering as cards sell
Included in Core

Buyers leaderboard

Ranks buyers by what they have spent and reorders itself as each card sells. Hide the dollar amounts or the sale counts if your room prefers that private.

A live viewer count overlay
Included in Core

Live viewer count

Your audience size on screen, updating as people come and go.

Live viewer count is in Core too. The five below are $14.99 each, one time, and all of them come with Lifetime.

Price any card, live, in seconds

Mid-show, put a card's market value on screen without breaking your flow. It reads the frame from OBS, so it works whatever platform you stream to.

Card Comp matching a card and showing its market price
1

Hold it up

Show the card to your camera and hit Comp this card, or type a name to search.

2

Pick the match

It reads the frame and pulls the closest cards with live market prices. Tap the right one.

3

It hits your stream

The price drops into your Card Comp overlay in OBS and your viewers see it straight away.

You bring your own API keys, so pricing stays accurate and yours.

Two pieces, then you're live

A Chrome extension reads your stream's live data. A desktop app turns it into overlays OBS can show. Everything runs on your own computer.

Extension

Reads your stream

Picks up the live sales, bids and viewers from your Whatnot tab.

Helper app

Turns it into overlays

Builds clean overlay pages and gives you one place to control them.

OBS

Straight into your scene

One click sends each overlay into OBS. That is the whole setup.

Your buyer data never leaves your machine.

Built to survive Whatnot changes

Tools like this break when the platform shifts. This one is built so it does not stay broken.

Self-healing

Fixes arrive on their own

When Whatnot changes something we push a fix that every install picks up automatically, usually within minutes. No update needed.

Monitored

We see it before you do

A live health monitor tells us the moment the data tap stops working, often before you would notice.

Private

Your audience stays yours

Buyers, sales and viewers stay on your computer. Nothing about your audience is sent anywhere.

This is a real show, not a mockup

A regular night selling singles, with the buyers leaderboard up the whole time. It reorders itself as each card sells. No edits, no staged numbers, nobody typing anything in.

LiveEvery sale moves the board the moment it lands.
Hands offReads your stream directly, so there is nothing to type in mid-show.
YoursPosition, colours and what stays private are all up to you.

What sellers say after using it

“We tested the Card Comp feature using two different Pokémon cards, and in both cases it successfully scanned the cards directly from our OBS camera feed, identified them correctly, and displayed the correct information on screen.”
James ChiazzaCCJames Inc. · Pokémon seller on eBay Live
“It's refreshing to work with a developer who is willing to improve the product based on real-world use cases.”
