Real overlays, live on a real Whatnot stream.

The overlays

Everything your stream needs

Four transparent OBS overlays, driven by your live Whatnot data — no manual updating.

Buyers leaderboard

Top buyers ranked in real time — by dollars spent or number of sales. Toggle amounts and counts, choose how many to show.

Live viewer count

Your real-time audience size, front and center, updating as people come and go.

Instant card comps

Snap the card on screen, identify it with AI, and drop its market price on stream in seconds — perfect for live breaks and auctions.

Floating logo

Your logo, gently floating around the screen — drift, bounce, or random. Upload, size, done.

The app

One calm control center

The desktop helper shows your live stream stats, ranks your buyers, comps cards, and hands OBS the overlay links — all in one window.

Overlay Deck control panel: live viewers, sales, dollar volume and the Top Buyers leaderboard
Live dashboard — viewers, sales & $ volume up top, the buyers leaderboard below, your OBS overlay links ready to copy.
Overlay Deck settings: license activation, subscription management, and anonymous-health diagnostics
Settings — activate your license, tune the leaderboard, add your own API keys, and set up the floating logo.
Card Comp

Price any card, live — in seconds

Mid-break, drop a card's market value on screen without breaking your flow. Powered by AI card recognition + live market pricing.

1

Hold it up

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

2

Pick the match

AI reads the frame and pulls the closest cards with live market prices. Tap the exact one.

3

It hits your stream

The price drops into your Card Comp overlay in OBS — your viewers see it instantly.

Card Comp results: AI best guess plus matching cards with set, rarity, market price and a TCGplayer link each
Real matches from your live frame — set, rarity, market price, and a View on TCGplayer link for each. You bring your own API keys; pricing stays accurate and yours.
How it works

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. All on your computer.

1 · Extension

Reads the live sales, bids & viewers from your Whatnot stream tab.

2 · Helper app

Turns that data into clean overlay pages. Your control center.

3 · OBS

Add the overlays as Browser Sources. That's it — you're live.

Everything runs locally — your buyer data never leaves your machine.

Built to last

Engineered to survive Whatnot changes

Tools like this break when the platform shifts. We built ours so it doesn't stay broken.

Self-healing

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

We're watching

A live health monitor alerts us the moment the data tap stops working — often before you'd even notice.

Private by design

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