Every part placed.Every defect dodged.
The 1D cut optimizer for metal shops, fabricators, and woodworkers. Nest bars, pipe, and lumber around defects, set your kerf, and get optimal cut layouts in seconds.

Same cut list. Fewer bars.
The exact same parts, cut in the order you'd list them versus nested by NestSolver. Less stock bought, less waste binned.
Three steps to optimal cuts
Enter your cuts
Stock length, kerf, and a list of parts. Add blocked zones for defects or edge trims, and set a minimum-drop threshold so anything shorter becomes scrap.
Optimize instantly
Two algorithms find the best arrangement. No waiting, no trial-and-error.
Review your plan
See every cut laid out on each bar. Copy the plan or refine your inputs.
Built for the shop floor
1D Cutting
Optimize bars, pipes, tubes, and lumber. First-Fit and Best-Fit algorithms find the most efficient arrangement.
Blocked Zones
Mark regions the saw must skip — knots, cracks, edge trims, anything you don't want a part landing on. The solver routes around them automatically.
Visual Layout
See every bar with colour-coded cuts, kerfs, and the trailing drop. Spot waste at a glance.
Waste Breakdown
Track exactly how material is lost — to kerfs, blocked zones, drops, and scrap between them.
Optimize by material
Cut optimizers tuned for how each material is cut and sold.

Frequently asked questions
Is NestSolver really free?+
Yes — the optimizer runs in your browser with no sign-up. Enter your cuts and get layouts instantly. A free account is only needed to save and reuse projects.
Does it account for saw kerf?+
Yes. Set your blade's kerf and NestSolver subtracts it between every cut, so the layouts reflect real material loss instead of ideal lengths.
Can it cut around defects?+
Yes. Mark blocked zones — defects, edge trims, or any span you can't cut — on each stock length, and the optimizer places parts around them automatically.
What materials does it support?+
Any 1D linear stock: metal bars, pipe, tubing, extrusions, angle, and lumber. If it's cut to length from longer stock, NestSolver can optimize it.
Do I need an account?+
No account is needed to try the optimizer. Create a free account when you want to save cut lists and revisit your optimized layouts.
