Free 3D Load Planning Sandbox

Test the P4P packing API in your browser — no code, no signup, no API key. Describe what you are shipping and what you are shipping it in, and get back a complete packing plan with exact 3D coordinates for every item.

What you can test

• Cartonization — pack individual products into the smallest shipping carton that fits, respecting weight limits and upright-only items.
• Palletization — stack cases onto pallets with heavier items on the bottom and a stable, repeatable pattern.
• Containerization — fill 20' and 40' shipping containers and see how much of the cube you actually used.
• Truck loading — plan trailer loads in side- or front-loading order so the load can be built in sequence.

How it works

1. Describe the items. Length, width, height, quantity, and weight. Mark anything that must stay upright, and set how much weight each item can carry on top of it.
2. Describe the containers. Your carton, pallet, container, or trailer sizes, with an optional maximum weight and cost. Dimensions can be given in inches, centimetres, or feet.
3. Run the pack. The sandbox sends one POST /api/pack request and renders the answer in 3D. You can step through the load one item at a time to see the order it was built in.

What you get back

For every item: the container it belongs to, its exact position, its orientation, and its place in the loading sequence. For every container: which items it holds, the total weight, and how much of its volume was used. Anything that could not be packed is reported separately rather than silently dropped.

Results can also be rendered as an animated isometric SVG, which is useful for dropping a picking or loading diagram straight into a warehouse document.

Free without an API key at one request per minute. With a key it is $0.03 per request with no rate limit, and new accounts start with $10 in credit.
