Re:Form is built on WebGPU — the modern graphics interface that lets a browser talk almost directly to your graphics card. That's what makes millions of triangles feel light. It also sets the requirements.

The short version

  • A desktop browser with WebGPU: current Chrome or Edge on Windows, macOS and Linux; current Firefox; Safari 26 on macOS.
  • A reasonably modern graphics card — anything from roughly the last decade that has working, up-to-date drivers. More video memory lets you push higher triangle counts comfortably.
  • A mouse is strongly recommended. Sculpting is a pressure-and-motion activity; a trackpad works, but a mouse (or a pen tablet that drives the cursor) feels far better.
  • Desktop only for now — phones and tablets aren't supported.

There is no download, no installer and no plugin. If the browser can run WebGPU, the full studio runs in a tab.

What happens without WebGPU

If your browser doesn't expose WebGPU, Re:Form falls back to a CPU engine automatically. Everything still works, but stroke performance and the practical triangle budget drop sharply — the GPU engine is the intended experience. The engine badge at the bottom of the left tool rail shows which engine you're on: GPU or CPU.

On Chrome and Edge, WebGPU is on by default in current versions. If the badge says CPU on a machine that should support it, updating the browser and the graphics driver fixes it in most cases.

How hard can you push it?

The mesh lives in your graphics card's memory and stays there, so the ceiling depends on the card:

  • The Free plan caps subdivision at about 12.5 million triangles — comfortable on mid-range cards.
  • Pro raises the ceiling to the full 50 million triangles, which wants a card with a healthy amount of video memory (8 GB and up is a good place to be).

Whatever the plan, Re:Form only spends triangles when you ask it to — see subdivision and the triangle budget for how to place detail deliberately.
