What makes this more than a basic cutting calculator?
Most free sheet cutting calculators pack a board one way and leave it there. Cutzilla runs a proper optimiser instead. You pick the cutting style that suits how you work, and it does the fiddly packing for you.
Cutzilla gives you two cutting strategies: a rip-first one for clean, edge-to-edge strip cuts that are easy on a table or panel saw, and a tighter one for maximum yield. Whichever you choose, it automatically lays the job out both ways round and keeps the version that wastes less board. The result is fewer sheets bought and less offcut left on the floor, from the same cut list.

Any sheet good: plywood, MDF, melamine, chipboard, acrylic, and even metal or glass, plus linear stock like bars and timber. You set the exact kerf for your blade and lock grain direction on the parts that need it.
Yes. You set your blade kerf once and Cutzilla builds it into every layout, so the plan you cut to is the plan you measured, with no quiet drift between the screen and the bench.
No. Cutzilla runs entirely in the browser on any device, so there is nothing to download, license per machine, or keep updated. Open it, plan your cuts, and go.
