BoothWall

A live photo wall for event booths, running on Fire TV with Amazon Vega OS.

Visitors scan the QR code on the TV, take a photo with their phone, someone at the booth approves it, and a second later it drops onto the wall as a polaroid. The same wall runs in any browser, so a laptop or a projector works too.

Where it came from

I built the first version, then called Live Wall, for next.app devCon 2026 in Berlin: a photo wall on a Fire TV running Amazon's new Vega OS. After the event I moved everything event-specific into one config file and cleaned it up into a sample anyone can run at their own booth. The devCon version has its own branch, devcon-2026, tagged v1.0.0. Its branding lives on in examples/nextapp-devcon.

Live Wall at next.app devCon 2026

The photos in the screenshots below were taken at that booth, and the demo site started out with the same set. The app's offline demo mixes them with generated booth scenes.

What you get

A TV app built for Vega OS

Eleven polaroids drift on the wall while it steps through every approved photo. New arrivals get a badge and a moment full screen. The side panel has the QR code and a live count per category. It's driven by the D-pad, Back is kiosk-safe, and every animation runs on the native driver so it stays smooth on a Fire TV Stick.

Press OK for the spotlight, a full-screen slideshow that keeps going on its own.

The same wall in a browser

The wall is one shared package. The TV renders it through React Native for Vega and the web app renders the same code through React Native for Web, live from the same API. Open boothwall.dedic.dev on a laptop and put it on a projector, or press F for full screen.

On a phone held upright the 16:9 wall would be a thin strip, so phones get a feed instead: the photos newest first, the category counts and a big "Add your photo" button.

A phone page and a Control panel

Visitors upload at /snap, the address behind the QR code. They pick a photo, add a caption and a category, and tick the consent box. Nothing goes public until someone at the booth approves it in the Control panel at /control, which also manages every photo (hide, edit, delete, in bulk too), shows live numbers and works as a remote for the TV.

A small Cloudflare backend

A Hono API on Cloudflare Workers, photos in R2, rows in D1, and one Durable Object that pushes each approval to every screen. It hibernates while nothing is happening, so a connected screen sitting idle costs nothing.

Try it

In your browser

No Vega SDK needed:

git clone https://github.com/ddedic/boothwall && cd boothwall
pnpm install
pnpm web:dev

Open http://localhost:5173. The config in the repo points at the public demo, so this is the real wall from boothwall.dedic.dev, live. Arrow keys, Enter, Space and Escape stand in for the remote. Add ?demo to run on the bundled photos instead, ?kiosk to hide the cursor and hints, or ?fullscreen to go full screen on the first key press.

On the Vega Virtual Device

You need the Vega SDK with the Virtual Device, Node 24 and pnpm 10:

export PATH="$HOME/vega/bin:$PATH"
pnpm tv:vvd:start:1080   # the Virtual Device at 1920×1080
pnpm tv:build:debug
pnpm tv:run:vvd

Use the Virtual Device's on-screen remote, or run pnpm remote for a bigger one in your browser. Scan the QR code on the screen with your phone and send a photo to the demo wall; it shows up once it's approved. To run without a network, set demo: true in the config and rebuild.

Make it yours

1. Configure. Everything event-specific lives in packages/shared/src/config/boothwall.config.ts: the event name, hashtag, categories, brand colours and where it deploys. Set deploy.apiDomain and deploy.webDomain to domains on your Cloudflare account, or to "" for free workers.dev addresses. docs/customising.md explains every field.

2. Brand it. Swap the logo, the TV backdrop and the icons for yours, keeping the file names (list). To see a fully branded wall first, run pnpm boothwall example nextapp-devcon.

3. Deploy. Run pnpm exec cf auth login, then pnpm boothwall setup. It creates the D1 database and R2 bucket in your account, sets the booth passcode, deploys the API and the web app, and writes the addresses back into the config. After that, pnpm boothwall deploy ships changes.

4. Put it on the TV. Build a release and install it on a Fire TV in developer mode, or on the Virtual Device:

   pnpm tv:build:release
   vega run-app apps/tv/build/armv7-release/tv_armv7.vpkg com.boothwall.app.main -d <device>
