CutListEngine

There is a gap between a parts list and the shop that will cut it, and the optimizer aims squarely at that gap. Real kerf width is entered so every gap in the layout represents material actually removed rather than empty space, an outside margin can be reserved for damaged edges, trimming allowance or clamps, and part rotation is allowed or blocked depending on whether grain and surface direction matter for the job.

Two layout approaches are offered. Free Nesting suits CNC follow-up, panel-saw interpretation or geometry-first estimation and can reach a proven sheet-count lower bound on small jobs, while the guillotine mode suits track saws, panel saws and through-cut workflows, with cut order following the generated slicing dependencies. Cut count is intentionally left out of non-guillotine layouts instead of being invented, and outside-margin trim cuts remain a separate shop decision.

Worked material examples cover plywood casework, MDF and melamine, and acrylic and signage. An unplaced-parts count is treated as a planning signal rather than an error: add stock, inspect oversized pieces, or compare constraints. The site advertises a free tier and states that no signup is needed.
