Built around how installs actually get planned.

Six tools that cover cabinet layout, canvas management, and export. Nothing you don't need.

Cabinet grid system

Configure exact rows, columns, and pixel pitch per cabinet, up to full UHD (3840×2160), then reuse the same grid across every screen in a project.

Multi-canvas support

Manage separate display zones and outputs inside one project file, right in the browser. No installation required.

Multi-format export

Export high-resolution PNG references or JSON data for downstream systems and vendors.

Spanning screens

Stretch a single screen across multiple cabinets with pixel math handled automatically.

Smart snapping

Snap to grid lines and cabinet edges for layouts that line up exactly.

Screen grouping

Group related screens so moving or editing one updates the whole set.

From blank canvas to exportable layout.

Three steps, no manual pixel math.
