Turn an idea into a real build plan.
Tell BudDIY what you want to build and it hands you a complete plan — an exact materials list, a step-by-step cut list, and an interactive 3D model you can orbit. Sheds, decks, patio pavers & water heaters.
Free to start. No trackers, no data selling. Your builds sync across your devices.
Your DIY
building buddy
From idea to build day
Three steps, no jargon
You describe the project. BudDIY does the math and draws the model.
Describe your project
Pick a type and enter a few dimensions — an 8×10 shed, a 12×16 deck. Plain choices, no engineering degree required.
See it in 3D
BudDIY builds a true-to-plan 3D model as you go. Orbit it, and switch between the finished look, the framing, and an x-ray view.
Get the full plan
A complete materials list, a step-by-step cut list, and an assembly manual. Take it to the lumber yard and start building.
What's inside
A real plan, not a rough idea
Every number is computed deterministically — no guessing, no hand-wavy estimates for the parts that have to be right.
3D you can trust
See it before you build it
Orbit a true-to-plan 3D model of your build. Flip between the finished exterior, the framing, and an x-ray view to understand exactly how every piece fits.
- Exterior, framing & x-ray modes
- Pinch to zoom, drag to orbit
- Geometry validated for soundness
Materials & cut lists
Everything you need, counted for you
BudDIY turns your dimensions into an exact shopping list and a step-by-step cut list — board by board, in the right build order. The arithmetic is deterministic, so it's the same every time.
- Shopping list with quantities
- Ordered cut list & assembly steps
- Save, revisit & share designs
Your Garage
Keep track of the tools you own — organized by category, with condition notes and a reminder of what you've lent out. Know what you've already got before your next project.
Shopping list
A running materials & tools list you can check off at the store, with a running total. Send a build's materials straight to it, or add your own items any time.

Why BudDIY
The math is done for you
Every quantity and cut is computed the same way, every time — so your shopping list and cut list actually add up. No spreadsheets, no back-of-the-napkin guessing, no surprise second trip to the lumber yard.
Materials counted, boards cut to length in build order, and a 3D assembly manual — from a couple of dimensions.
