Active Break

Ureka is checking which Whatnot break is pinned.

You no longer need to confirm this manually. If you have multiple breaks, just pin the one you are running.

Detecting…
Keep your Whatnot Seller Dashboard open while breaking. Ureka reads this page to automatically update your board.
Live Control Panel

Optional companion panel for connection status, Streamer Moments, diagnostics, and manual backup controls. It does not need to remain open for automation transport.

Manual Backup Controls

Ureka normally updates automatically from Whatnot. Use these controls only if you need to make a manual correction during a live break.

Teams not in randomizer

For reduced league breaks, Ureka first reads through the full virtualized Whatnot roster automatically. If Whatnot cannot be read completely, use the Live Control Panel to choose the excluded teams manually.

Help & Setup

Set up Ureka, connect Whatnot, and go live confidently.

Follow the Quick Start once. After that, each break is: build or load a board, press Activate Break, and go live. Your OBS link never changes. Looking for something specific? Press Ctrl/Cmd+K (or /) to search every feature and be taken straight to it.

Setup Reference Troubleshooting Install from Chrome Web Store
1

Quick Start

Complete these steps in order for the cleanest setup.

1

Install the extension

Open the official Chrome Web Store listing and click Add to Chrome. Chrome installs and updates the extension automatically.

2

Sign in to Ureka

Open Ureka Stream Studio in the same Chrome profile and sign in. The extension uses this browser session.

3

Build or load a board

Choose a Team Board or Chase List and pick your sport or add your spots. Use Edit Design for the look, and save the board so you can load it next time. Review the live preview.

4

Copy your OBS link once

Click Copy OBS URL. This is your permanent link: it is the same for every break, so you only do this once.

5

Add the Browser Source

Create one OBS Browser Source named Ureka Stream Studio, paste the link, and set Width to 1080 and Height to 1920.

6

Connect Whatnot, then Activate Break

Open the Seller Dashboard, connect the username, and pin the break you are running. When the Whatnot Connection area reaches READY TO BREAK, press Activate Break in the bar at the bottom of the page. Press End Break when the show is over.

After the first OBS setup: leave the Browser Source alone. Its link never changes. For each new break, load your board in Ureka and press Activate Break; the new board appears in OBS on its own.
2 Install the Chrome Extension
  1. Click Install from Chrome Web Store on this page or in the Whatnot tab.
  2. On the official Ureka Stream Studio Connector listing, click Add to Chrome.
  3. Approve Chrome's installation confirmation.
  4. Click the Chrome Extensions puzzle icon and pin Ureka Stream Controller.
  5. Open Ureka Stream Studio and sign in using the same Chrome profile.
  6. Open the extension. Confirm it recognizes the Ureka account, then enter the seller's Whatnot username.
Updating later: Chrome Web Store updates are installed automatically. Reload the open Whatnot Seller Dashboard after an update so its reader uses the new version.
Official installation: Ureka is distributed through the Chrome Web Store, which handles installation and updates automatically.
3 Add Ureka to OBS

Create the Browser Source once

  1. In the correct Whatnot scene, click the + button in the OBS Sources panel.
  2. Select Browser.
  3. Choose Create new and name it exactly Ureka Stream Studio.
  4. In Ureka, click Copy OBS URL and paste it into the Browser Source URL field.
  5. Set Width: 1080.
  6. Set Height: 1920.
  7. Click OK, then position and scale the source in the scene as needed.

For every new break

  1. Build or load the Team Board or Chase List you want to run.
  2. Press Activate Break in the bar at the bottom of Ureka. The board is published to your OBS link and Whatnot automation starts.
  3. Go live. You do not touch OBS: the same Browser Source shows the new board.
  4. When the show ends, press End Break. The display goes off air and your link stays the same for next time.

Switching boards mid-stream? Open the other board and press Switch to This Break. If the display ever goes blank, Restore Display publishes the current board again.

OBS Browser Source properties with Ureka URL, width 1080 and height 1920
The Browser Source should be named Ureka Stream Studio and remain set to 1080 × 1920.
Do not paste the app's normal page URL into OBS. Always use the link created by the Copy OBS URL button. It opens the clean display and is your account's permanent link.
4 Team Board Workflow

Choose a sport

Select MLB, NBA, NFL, NHL, or Multi. To use your own spots, open Add spots and type a name or paste a list, one per line. Drag to reorder and use the x to remove one. On a big board, search or sort the spots A to Z.

Mark spots taken

Tap a spot when it sells and the board on stream follows. Reset taken makes every spot available again. If you change something by mistake, Undo appears at the bottom of the page.

Review the preview

The live preview reflects your design and current setup. Check the title, tiles, counter, and ticker, then press Activate Break.

Control during a break

Automatic Whatnot sync marks teams taken. For a reduced MLB, NBA, NFL, or NHL break, Ureka reads through Whatnot’s virtualized team list, compares the complete observed roster with the league board, and blacks excluded teams out using the normal taken-team appearance. If the full roster cannot be read, use Teams not in randomizer in the Live Control Panel as the safe fallback.

5 Chase List Workflow

Enter the chase list

Open Edit spots and use Add spots to type a name or paste one item per line. Give the display a clear title.

Purchased names

By default, purchased chase names stay visible and are clearly marked TAKEN. You can optionally remove them from the board in Properties.

Top Chasers, regions and designs

Mark your best items as top chasers, split a long list into named bands with Regions, and use Edit Design to change the look. Confirm everything in the live preview.

Correct items in the extension

Once the Chase List is active, Manual Backup Controls show the exact active list. Remove or restore items from the controller only when a live correction is needed.

6 Save, Load and Design Your Boards

Save a board

On the Team Board or Chase List, Save Changes updates the board you loaded and Save as New keeps a copy under a new name. A saved Team Board shows only on the sport it was saved on.

Load a board

Pick one of your saved boards, then press Load. New board starts from the sport's default teams; for a Chase List, New starts blank. Ureka asks before replacing changes you have not saved.

Edit Design

Open Edit Design for the Board Designer: layouts, colors and fonts, a scrolling ticker, your logo and show name, and Stream Moments such as Giveaway or Last Spot, all with a live preview.

Saved designs

Save a look under Saved designs and reuse it on other boards. A design only changes appearance; it never changes your teams, chase items, or break contents.

7 Multi-sport, Tiers, Groups and Regions

Multi-sport Team Breakdown

Choose the Multi chip after NHL. You get one spot per NFL team, and each spot can also carry NBA and MLB teams, laid out in North, East, South and West rows.

Groups

On a Multi board, open the Groups tab to attach other teams to a spot, up to four each. The spots that ride together are shown on the display and saved with the board.

Tiers

Use Tiers to mark Tier 1 and Tier 2 spots in gold and silver. Pick the colors in Edit Design. A tier key appears on the display.

Regions

Arrange spots into labelled bands (North, East, South, West, or your own) on any Team Board or Chase List. Edit them in Edit spots; they are saved with the board and drawn on the display.

Team colors

Give any spot its own tile color from the Colors mode on the Team Board.

8 Ureka Stream Controller

Connection Status

Confirm the extension shows the correct Ureka account, Whatnot seller, active board, and automatically detected pinned break before you press Activate Break. The controller's board list includes your saved Team Boards, so you can pick the right one there too.

Stream Moments

Trigger Stash or Pass, See 2 Pick 1, 2 Teams, 2 Players, Giveaway, Trade Window, Last Spot, or a custom message.

Manual Backup Controls

For Team Board, mark teams available or taken. For Chase List, remove or restore chase items. These are failsafe controls; normal updates are automatic from Whatnot.

Teams not in randomizer

Normally Ureka detects reduced league rosters automatically by reading the full Whatnot randomizer list. Use this selector only as a manual fallback when Whatnot prevents the connector from collecting the complete roster.

Open Display

Open the clean display in a browser to verify it independently from OBS. The display only shows a board after you have pressed Activate Break.

Restart Sync

Use this after opening or refreshing the Whatnot Seller Dashboard, or when the extension has stopped receiving changes.

Emergency Correction

Use manual controls when the live Whatnot widget and the Ureka output do not match. Correct the board, then verify the display.

Start-of-Break Checklist

Run this before every show.

10 Troubleshooting

Extension says Disconnected

Confirm Ureka is signed in in the same Chrome profile, reopen the Whatnot Seller Dashboard, then click Restart Sync. Reload the extension from chrome://extensions if needed.

OBS shows the old break or nothing

Load the board you want and press Activate Break (or Switch to This Break). If it reads Restore Display, press it to publish the board again. After End Break the display is blank on purpose.

Manual controls show the wrong board

Return to the correct Team Board or Chase List and press Switch to This Break. The controller follows the board that is active.

Browser Source is tiny

Open Browser Source properties and confirm Width is 1080 and Height is 1920. Then reset or resize the source transform in the scene.

Browser Source is blank

First check that a break is active: the display stays blank until you press Activate Break. Then open the OBS link in Chrome. If it does not load, click Copy OBS URL while signed in and paste it into the Browser Source again.

Team or chase state is wrong

Use Manual Backup Controls to correct the item immediately. Then restart sync and visually confirm the clean display matches the current Seller Dashboard.

Updates are not appearing

Confirm the correct Whatnot break is pinned, refresh the Seller Dashboard, restart extension sync, and verify the extension is connected to the correct seller and Ureka display.

Can't find a setting?

Press Ctrl/Cmd+K (or /) and type what you want, like tiers, ticker or save a board. Ureka takes you there and points at the control.

Two extension versions are installed

Disable or remove the older copy. Only one Ureka Stream Controller version should be enabled at a time.
