Cabinet & furniture CAD

Kerfwise

Design cabinets and furniture, get cut lists, optimised sheet layouts, costs and drawings.

Kerfwise is a free cabinet and furniture CAD that runs in your browser. Build kitchens, wardrobes, bookshelves, desks, tables and beds from parametric cabinets with real joinery, then get a grouped cut list with edge banding, guillotine or CNC sheet layouts with yield and offcuts, a hardware list, a full cost estimate and dimensioned production drawings with drilling. Projects stay on your device; the same engine is available as API and MCP tools.

Features

  • Parametric cabinet library

    Base, wall, tall, drawer bank, blind corner, open shelf, wardrobe, bookshelf, desk, table and bed frame — every size, material and option is a live parameter.

  • Real joinery rules

    Butt + screws, dowels, confirmat, pocket screws, cam & dowel, dado, rabbet, mortise & tenon and dovetail drawers change part sizes, drilling and hardware.

  • Kitchen layout mode

    Draw walls, windows and doors, drop appliances, and cabinet runs snap to the walls. Worktops are generated with overhangs, corner joints and sink/hob cut-outs.

  • 3D view with exploded & section

    Hand-written WebGL viewer with orbit, pan, zoom, wood-grain materials, exploded assembly, section plane, dimensions and a click-to-measure tool.

  • Elevations

    Wall elevations with cabinets, fronts, handles, worktops, windows and dimension chains, plus front/side/top views of every cabinet.

  • Automatic cut list

    Grouped parts with finished and cut sizes, grain direction, edge banding per edge (L1/L2/W1/W2) and banding metres — CSV export and CSV import.

  • Sheet nesting optimizer

    Guillotine (panel saw) and MaxRects (CNC) with kerf, trim margins and grain lock on standard sheets like 2800 × 2070: yield, offcuts and cut sequence.

  • Grain-aware materials

    Melamine, veneered MDF, plywood, solid panels, HDF backs, linear stock and worktops, each with its own sheet size, price, grain and colour.

  • Drilling & hardware

    System 32 shelf-pin rows, hinge cups by door height, mounting plates, slide screws and joint holes on every part, with a priced hardware list.

  • Cost estimate

    Sheets or used area, edge banding per metre, hardware, editable labour minutes, worktop cut-outs, markup and tax — all prices editable.

  • Production drawings

    Dimensioned part drawings with ordinate hole positions, assembly views and a print view for the workshop or a PDF.

  • Open formats

    JSON project files, CSV cut and hardware lists, SVG and hand-written DXF R12 sheet layouts and part outlines, PNG renders.

  • Local-first & private

    Autosave in your browser, recent projects, undo/redo, no account, no upload. Share a project as a file or a link.

  • For AI agents

    Three engine tools — cabinet builder, cut list and sheet nesting — via JSON API and MCP, with links that open results in the app.

Templates

Start from a ready-made project and change it to fit.

For AI agents

Kerfwise runs on a deterministic engine. The same functions are available as tools with a JSON API and MCP, so scripts and AI agents get exactly the results the app shows.

Frequently asked questions

Is Kerfwise really free?

Yes. It runs entirely in your browser, needs no account and stores projects locally. The site is financed by ads outside the workspace.

Where are my projects stored?

In your browser (IndexedDB) on this device, saved automatically. Use File → Save to keep a .kerfwise.json file or to move a project to another computer.

How accurate are the cut sizes?

They follow the joinery rules shown in each tool’s methodology (e.g. side height = cabinet height − plinth, grooved back = inner width + 2 × groove depth, cut size = finished size − banding). Always check your own hardware data and do a test cut before cutting expensive sheets.

Which sheet sizes and saws are supported?

Any sheet size, with presets like 2800 × 2070, 2440 × 1220 and 3050 × 1220. Guillotine layouts can be cut on a panel saw or table saw; MaxRects layouts are tighter and meant for CNC routers.

Can I use it for things other than kitchens?

Yes: wardrobes, bookshelves, desks, tables, bed frames and drawer units are built in, and you can add loose parts by hand or import them from CSV.

Can I send the layouts to my CNC or CAD program?

Export the sheet layouts or part outlines with drilling as DXF R12 (millimetres, separate layers for parts, labels, offcuts, cuts and holes) or as SVG.

Can an AI agent create a project for me?

Yes. The kerfwise-cabinet-builder, kerfwise-cut-list and kerfwise-sheet-nesting tools are available via the JSON API and MCP. Results include an “open in app” link with the project in the URL fragment.

Limitations

What Kerfwise does not do (yet):

  • Cabinets are rectangular: no angled, curved or diagonal corner cabinets (blind corners only).
  • Worktop corners are butt joints; mitred corners and L-shaped single-piece tops are not modelled.
  • Nesting is heuristic (very good, not proven optimal) and nests rectangles only.
  • Hardware positions follow common European (System 32, Blum-style) defaults; check your exact hinges and slides.
  • No CNC toolpaths/G-code; DXF is for import into CAM software.
  • The 3D view uses simple box geometry (no rounded edges, handles as bars) and needs WebGL.
  • Phones get a simplified, mostly read-only layout; editing is best on a tablet or desktop.
