Everything a haunt needs

Modular canvas

Drag-and-drop walls, doors, actor runs and FX nodes on a snapping 1×1, 4×4 or 4×8 ft grid.

Dark 3D walkthrough

Walk your haunt in first person — dim lights, strobes and fog, plus line-of-sight and scare-angle analysis.

Safety validator

Automatic corridor-width and egress checks, so you catch dead-ends and pinch points before the inspector does.

Guest throughput

Estimate capacity per hour from path length, bottlenecks and group batching — plan your ticket pacing.

BOM + printable PDFs

Auto-counted material lists and print-ready plans: fire-code corridor annotations for inspectors, scare symbols for staff.

Cloud saves

Keep every haunt in one place and share plans with your crew — accounts and cloud saves are coming soon.

See it in action

“The Hollow” is a 40×40 ft sample haunt: three rooms, an 8-ft gallery corridor, jump-scare zones, hidden actor runs and a fog-and-strobe FX plot — all wired to the safety validator and ready to walk in 3D.
