A free, fast, browser-based cabinet and plywood designer.
Turn your ideas into accurate cutlists in minutes.
Designing shop furniture usually means juggling tools: you model in one app, export to another to get a part list, and hunt down a plugin for your cut layouts. Panelizer folds all of that into one place.
Model, extract parts, and generate optimized cutlists — together, for free, directly in your browser.
It’s built for speed and simplicity, not to replace heavyweight CAD.
- Need full parametric modeling? SketchUp or Fusion 360 are the right tools.
- Want to sketch a cabinet and walk into the shop with a cut diagram 5 minutes later? That’s Panelizer.
- Direct Manipulation: Create, move, and resize plywood panels right in the 3D workspace.
- Smart Snapping: Assembly-aware snapping ensures your joints line up perfectly.
- Error Prevention: Visual overlap detection catches mistakes before you make a cut.
- Ultimate Flexibility: Mix multiple materials and thicknesses in the exact same build.
Working in 18mm plywood but thinking in inches? No problem. Pick your preferred unit for anything, mix and match freely, and Panelizer handles the conversions for you.
Every panel becomes a manufacturing part automatically. Get a clean, real-time list detailing dimensions, material, thickness, and quantity. When you're ready to order or build, hit export to generate a CSV.
One of Panelizer's biggest strengths. Tell it what sheet goods you have on hand, and its optimization engine handles the rest:
- 🧩 Nests parts onto sheets to minimize waste.
- 🌲 Respects grain direction for visible panels.
- 🪚 Accounts for kerf and edge margins.
- 🚨 Flags missing stock or insufficient sheets.
The result? A visual cut diagram that's actually useful at the saw.
