Offline-first Multi-map More Planning friendly

Plan your RimWorld base layout, fast.

Draw rooms, measure distances, keep multiple drafts, and export/import ASCII layouts for the More Planning [1.6] mod. Your maps are saved locally in your browser by default.

Open Designer Gallery (opt-in)

What you can do

  • Save layouts locally (offline-first)
  • Create / rename / duplicate / delete maps
  • Import/export ASCII to clipboard
  • Overlay a background image for tracing
  • Pan & zoom with mouse + WASD

Fast iteration

Sketch multiple ideas, switch maps instantly, and keep drafts separated.

Offline by default

No account needed to start. Your work stays in your browser unless you choose to publish.

Share when you want

Use the Gallery only if you want a public copy. Local maps remain local.

How it works

  1. Create a local map (or duplicate a draft) from inside the Designer.
  2. Draw your plan with rectangles, circles, lines and the eraser tool.
  3. Export to ASCII for More Planning, or import an existing layout to edit.

Controls

Draw Left click / drag
Pan Middle click (wheel) or WASD
Zoom Mouse wheel

Tip: add a background image overlay to trace an in-game screenshot.
