Browser support and performance tips

Which browsers we recommend, and a few quick fixes if things feel sluggish — especially in the 3D view.

Updated 2026-06-10

RoomSketch3D runs on any modern browser. 3D view performance depends on your hardware.

Step by step

1
Supported browsers
Chrome, Safari, Edge, Firefox — latest two major versions. Opera, Brave, Arc — work fine. Internet Explorer is not supported (deprecated by Microsoft years ago).
2
If the 2D canvas feels slow
Designs with many floors and 100+ pieces can slow down. Try: closing other browser tabs; reducing the number of floors visible; turning off the grid temporarily.
3
If the 3D view feels slow
3D rendering is GPU-intensive. Try: closing other tabs; switching to integrated graphics if your laptop has both; reducing the visible floor count on multi-floor designs.
4
Mobile performance
iOS and Android apps run native rendering — much faster than mobile-browser 3D. If your phone's browser struggles, switch to the app.

Draw it, furnish it, walk through it in 3D — on web, iOS, and Android.
