Configurable grid

Set any number of rows and columns per board, matching whatever space you're displaying it in.

Send from anywhere

Push text from the dashboard or via a per-board API key over a simple HTTP endpoint.

The real sound

Every character flips through its sequence with an authentic mechanical clack.

What is a split-flap display?

Split-flap (or "flip-flap") boards are the mechanical displays you might remember from old train stations and airports — each character sits on a set of hinged flaps that click forward through a sequence of letters and numbers until it lands on the right one. FLAPWALL recreates that same look, sound, and motion digitally: build a board of any size, then update it in real time from a dashboard or an API — no physical hardware required.

Where it's used

Anywhere a room needs to see the same information at a glance.

Airports & transit

Gate numbers, departure times, and delay notices — the classic use case, now easy to run on any screen.

Production floors

Live line status, shift counts, and downtime alerts, visible from anywhere on the factory floor.

Monitoring & ops

Uptime, incident status, and key metrics on a shared screen in a NOC, ops room, or standup area.

Offices & events

Welcome messages, meeting room schedules, queue numbers, or wayfinding — wherever a shared display helps.
