A complete browser-based island layout planner
Edit the full island grid, place buildings at game-matching scale, and keep your latest layout saved in this browser.
TomoLayout is a free online island layout planner and island grid tool for Tomodachi Life: Living the Dream. It helps players plan terrain, paths, buildings, homes, facilities, and custom objects before making changes in-game.
Edit the full island grid, place buildings at game-matching scale, and keep your latest layout saved in this browser.
TomoLayout is a planning tool. It does not read, edit, or synchronize with Nintendo Switch save data.
TomoLayout saves the current project to local storage on this device and browser. It does not sync layouts between devices and does not store layouts on the TomoLayout server.
The planner includes the production tools already available in the editor, not just a static grid.
Generate a centralized, clustered, maze-like, or planned-city layout. The automatic layout generator can create a starting point, then you can lock the buildings you want to keep and generate terrain around them, or generate buildings and paths around existing terrain.
Paint, fill, erase, draw straight lines, select, move, rotate, and lock. Adjustable 1x1, 3x3, and 5x5 brushes make both detailed edits and large terrain changes faster.
Island ideas often travel across screenshots, languages, and social platforms. TomoLayout helps you keep track of public reference links while you plan, so you can remember which creators inspired your layout and include a simple creator credit when you share your own plan.
Autosave protects your latest layout, while four manual browser save slots let you keep alternate versions on the same device. Export JSON when you need a portable or long-term backup.
Need a quick starting point? Begin with a heart, crescent, or star terrain sample, then edit every part of the island yourself.
Shape the terrain, draw paths, and arrange buildings, homes, and decorations using dimensions that match Tomodachi Life: Living the Dream.
Rotate and zoom the 3D preview to check building and object height, crowded areas, and the overall balance of your island.
Export a share-ready PNG with a small TomoLayout logo in the lower-right corner, or export JSON to back up the editable project.
Move, rotate, replace, or undo anything in the planner before spending time rebuilding the real island.
Works in modern desktop browsers and mobile browsers on iOS and Android. Touch controls are designed for phones and tablets, while mouse and trackpad controls work on PC.
TomoLayout saves your layout automatically while you work. Reopen the planner on the same device and browser to continue where you left off.
The planner includes the production tools already available in the editor, not just a static grid.

Island ideas often travel across screenshots, languages, and social platforms. TomoLayout helps you keep track of public reference links while you plan, so you can remember which creators inspired your layout and include a simple creator credit when you share your own plan.
Creator credit records where your inspiration came from; it is not a license to repost, copy, or remix the referenced work. Open the original link to review the source and any available usage notes before reusing another creator’s design.

Rotate and zoom the 3D preview to check object height, crowded spaces, and the island’s overall composition.

TomoLayout saves the current project to local storage on this device and browser. It does not sync layouts between devices and does not store layouts on the TomoLayout server.
Clearing browser data, changing browsers, or using private browsing may remove the saved project. Export a JSON backup for any layout you want to keep.
Autosave is convenient, but it is not a substitute for a backup. Use manual browser save slots when you want to compare alternate layouts on the same device. Export JSON before clearing browser data, using private browsing, changing browsers, switching languages, or moving to another device.
