Starship deck plan generator

One click gives you a whole ship — bridge forward, drive aft, crew, galley, medbay, cargo and engineering off a central corridor, every room furnished, numbered and keyed with a GM note. Pick shuttle, corvette, freighter or station; intact or derelict. Then change anything: it's a normal, editable plan.

Generate a ship in the demo How it works

A generated freighter deck plan with colour-coded numbered rooms and a room key

What you get

Rooms by role — a bridge with viewports, crew quarters with bunks, a galley, medbay with an autodoc and cryo bank, cargo with containers, engineering with a reactor, a drive section, and on bigger hulls a lab, hangar, armoury, life support and escape pods.
Doors and airlocks where they belong, so the plan plays correctly in a VTT with dynamic lighting.
A room key — numbered badges on the map, names and short GM notes in the panel, printed with the PDF and exported as Markdown.
Derelicts — hull breaches, half the lights out, colder notes.
Two decks on freighters and stations, linked by a matched ladder or lift.

Then export

Universal VTT (.dd2vtt) carries the image plus walls, doors, windows and lights — Foundry VTT, Roll20 and Owlbear Rodeo import it ready to play. Also PNG, and a PDF tiled at 1″ per square for miniatures.

Works with

Any grid-based sci-fi game: Mothership, Alien RPG, Traveller, Stars Without Number, Death in Space, Coriolis. Squares are 5 ft / 1.5 m by default; change the unit label to suit.
