Design it. Cut it. Build it.
Timberly is a free 3D woodworking planner for beginners. Design furniture from real lumber — and get your cut list, cutting diagrams and shopping list automatically.
No sign-up. No install. Runs in your browser and saves on your device.
From viewport to photo
One click turns your working 3D view into a photo-real render. Drag the divider.
Everything between the idea and the lumber run
Built for first projects — honest about wood, sizes and what your tools can do.
Real lumber, real sizes
Drag 2×4s, plywood and boards from a US & EU stock catalog. A "1×" is 19 mm here too — no imaginary dimensions.
Cut list & shopping list
Always up to date as you design. Board and sheet cutting diagrams squeeze the most out of every purchase.
Joinery that fits your tools
Tell Timberly what tools you own and it suggests joints you can actually make — and warns about shelves that would sag.
Rooms & built-ins
Draw walls, doors and windows, then design closets and cabinets that fit the space — with cut-to-fit helpers.
Parametric design
Drive sizes with named parameters and formulas like $width / 2. Save your builds and reuse them across projects.
Community library
Browse builds shared by other makers — no account needed. Rate and comment, pin favorites, and publish your own designs, parameters included.
Made for beginners
AR preview on your phone, guided interactive tutorials, and an interface in 17 languages.
From idea to build day
Sketch it in 3D
Start from a template, generate a cabinet, or drag boards in one by one. Snapping and alignment keep everything square.
Let Timberly check it
Collisions, unconnected parts, sagging shelves and impossible joints show up before you cut anything.
Print and build
Take the shopping list to the store, the cutting diagrams to the saw, and Shop mode to your phone at the bench.
Power tools, when you're ready
Advanced features stay out of your way until you want them.
AI rendering
Turn your exact camera view into a photo-real image — pick a scene style and floor, preview it full screen, download it. Works with your own Google Gemini key.
AI assistant
Chat with an assistant that designs alongside you — it can add, move and resize parts in your project. Your API key goes straight from your browser to the provider, never through us.
Physics simulation
Flip on gravity and watch your build react — a quick, honest answer to "will it actually stand?" before you cut anything.
Load & sag simulation
Optional engineering checks: assign real shelf loads — books, display, heavy shop gear — and get span warnings before the wood bows.
Your designs stay yours
Timberly is local-first: projects save in your browser and never need an account. Sign in only if you want free cloud sync across devices. Project files are plain, documented JSON — you can export everything, anytime.
Frequently asked questions
Is Timberly really free?
Yes. The planner is free and needs no account — projects save right in your browser. Signing in is optional and only adds free cloud sync across devices. The AI rendering and assistant features use your own API key.
Do I need to install anything?
No. Timberly runs in any modern desktop browser — nothing to download or install. The AR preview works in your phone's browser too.
Does it work with imperial and metric measurements?
Both. Enter fractions like 1‑3/4" or millimeters, pick from real US and EU lumber sizes, and use the interface in 17 languages.
Can it really generate my cut list?
Yes — the cut list, board and sheet cutting diagrams and a shopping list update live as you design. Print them, or open Shop mode on your phone at the saw and check cuts off as you go.
What can I design with it?
Furniture and shop projects built from real lumber: tables, bookshelves, cabinets, workbenches, planters — and closets or built-ins fitted to your room, using walls, doors and windows you draw yourself.
