About Gridsnap
The story behind the free floor plan editor
The Story
I built Gridsnap because I couldn't find a good free floor planner that works online. I needed to create plans and drafts quickly — sketch out a room, place some furniture, get the measurements right — without downloading software or paying for a subscription.
The existing options were either too expensive, too slow, required a desktop install, or locked basic features behind a paywall. So I built the tool I wanted to use.
The Technology
Gridsnap is built with modern web standards — React, TypeScript, and HTML5 Canvas. The entire application runs client-side in your browser. No server processes your data. No cloud storage holds your files.
Your floor plans stay on your device in browser local storage. Export to PDF or PNG anytime — directly from the browser, with no round-trip to a server.
The Philosophy
Speed and simplicity come first. The most important thing about Gridsnap is how easy and fast it is to put a plan together. Open the editor, start drawing walls, drop in some doors and furniture, add dimensions — done. No tutorials needed, no complex setup.
Precision is built in, not bolted on. Every measurement is in millimeters. Snap to grid keeps things aligned. But the tool never gets in your way — it should feel fast, not fiddly.
