Kerfo: Cut List Optimizer

Kerfo is a cut list optimizer and cutting list app that turns your parts list into a plywood cutting plan in seconds: enter your parts or pick a cabinet, choose your sheets, and get a guillotine cutting diagram to follow at the saw. Real inch fractions, grain direction, numbered cut steps. Works offline. No account. No ads.

WHAT IT DOES
• Sheet cutting optimizer for plywood, MDF, melamine, chipboard / MFC and any sheet material
• 1D mode for linear stock: a lumber cut list for face frames and trim, or pipe, metal bars and tubing
• Imperial fractions (1/16" by default, 1/32" or 1/8" optional) and metric
• Saw kerf, edge trim, grain direction lock and part rotation
• Edge banding on any of a part's four edges, with parts entered at finished size or cut size
• Mix sheet sizes, set limited or unlimited stock, and use up your offcuts first
• Rip or crosscut first, with the total number of cuts
• Yield %, sheets used and waste area, and a note when a layout provably uses the fewest sheets or bars
• Numbered cut steps on screen, one cut at a time

CABINETS IN, CUT LIST OUT
A cabinet parts calculator for frameless (European-style) boxes. Pick a base, wall, tall / wardrobe, sink base, drawer unit or bookcase, enter its outer size, and get its cabinet cut list: sides, top and bottom or rails, back, shelves, a centre divider, overlay doors, drawer fronts, plinth or recessed toe kick.
• Back in a groove, nailed on, inset or none. Thin backs go to a project of their own
• Fractions or mm. Every cabinet has its own size and depth
• Banding on front edges and on all edges of doors and drawer fronts
• Add cabinet after cabinet to one project. Undo, or edit a cabinet later
• Drawer boxes, corner units, face frames and hardware aren't generated: add them as parts
Not a 3D or kitchen design app. The cabinet generator is free. Pro is one payment, no subscription.
