What this is
Tomodachi Grid is a free, browser-based toolkit for designing in Tomodachi Life: Living the Dream. It contains four tools that solve the most common workflow problems players run into:
- Grid Maker — convert any image to a paint-by-numbers Palette House design
- Grid Size reference — exact canvas and brush dimensions
- Island Layout Planner — drag-and-drop layout sketches
- Designs Gallery — curated community art with recipes
What this isn't
Tomodachi Grid is not made by, endorsed by, or affiliated with Nintendo. Tomodachi Life is a registered trademark of Nintendo. We don't extract data from the game, we don't host copyrighted Nintendo artwork, and we can't import designs directly into Switch — the game has no such API.
Our Grid Maker uses an approximation of the in-game palette. For the original community palette calibration project (NPO-197, DurchBurch, marinesnow.rika and others), see living-the-grid.com.
How it's built
Every tool runs entirely in your browser using vanilla JavaScript and the HTML Canvas API. Nothing is uploaded to a server. The site is built with Astro as a static site and hosted on Cloudflare Pages, which is why it's fast and free to operate.
Why it exists
Tomodachi Life: Living the Dream launched in April 2026 and immediately created a wave of players wanting to recreate their favourite logos, characters and outfits on the Palette House canvas — without any built-in image import. Existing tools either focused on a single workflow or required signup. We wanted one place that solves the whole pipeline from image to in-game art, plus the adjacent problems (planning your island, looking up brush dimensions, browsing community work).
