Make every pixel count.

The LED screen engineering software. Lay out the wall with real panels and processors. Wiring, power, and pixel maps are computed as you design, and every drawing follows. The fastest way to document an LED video build.

Free to start. Nothing to install.

What it does

Complete LED wall engineering.

More rigorous than a calculator, and faster than the bigger CAD suites. One engineering document where the drawings, schedules, and labels are computed from the wall itself.

Topology + load engine

The math is checked on every edit

Lay out real panels and processors and the engine computes data strings, processor ports, switch cascades, backup paths, and numbered circuits as you go.

Four workbenches, one file

3D, mapping, sheets & video

See the wall in 3D, verify the pixel map panel-by-panel, pixel-by-pixel, lay out drawing sheets, and drive live video, all from the same document. Edit anywhere; everything downstream regenerates.

Equipment library

Real gear, or your own catalog

Build from a community library of panels, processors, and switches, or keep a private catalog of your own gear that matches what your shop actually runs.

Paperwork that agrees with itself

Elevations, schedules, BOM & labels

Export pixel-faithful PDF drawings, real DXF, pixel maps, wiring diagrams, power and data schedules, bills of materials, and cable-label CSVs. Every sheet generated from the one source of truth.

Cloud projects & sharing

Send a link, not another PDF

Save a version at every milestone and share a snapshot link anyone can open in a browser. Autosave keeps cloud projects current, exports carry a scan-to-open QR, and your whole team draws from one shared equipment library.

FINAL_v7_final.pdf

Runs anywhere

Browser, desktop, fully offline

Works in the browser with zero hardware, or as a desktop app that runs completely offline for the job site, the secure facility, or the truck with no signal.

How it works

The fastest way to document an LED video build.

01 Design

Design.

Lay out the wall with real panels and processors. The engine recomputes strings, processor ports, circuits, and amperage live, with backup paths and switch cascades included. The wall you draw is the project, not a picture.

02 Document

Document.

Generate a packet that agrees with itself: elevations, wiring diagrams, power and data schedules, pixel maps, BOMs, and cable-label CSVs. Change the wall and every sheet follows.

03 Deploy

Deploy.

Export pixel maps and put them on the wall to verify the build panel-by-panel, or run test patterns and live video through the real processors to prove the wall before doors.

Faster than the bigger CAD suites: you design the wall, and the drawings draw themselves.

The math is checked on every edit.
