For site owners
Put a 3D container load calculator on your own site
One iframe and no script. Your visitors get the real planner — plain-English input, stacking and weight rules, an interactive 3D plan — without leaving your page or making an account.
Free to embed. No key, no signup, no per-view charge.
The snippet
Paste this where you want the calculator. Change the height if you want it taller; everything else works as it stands.
<div style="max-width:100%">

width="100%" height="720" loading="lazy"

Running, on this page
This is the same iframe the snippet gives you, on this page, right now. Type a load into it — nothing here is a screenshot.
The embed is the planner with the chrome removed: no navigation, no cookie banner, no analytics, and it never asks your visitor to sign in before they get a result.
Options
Add these to the iframe URL. Anything not on this list is stripped, so the planner keeps one canonical address.
| Parameter | What it does |
|---|---|
embed=true |
Required. Serves the planner alone — no header, no footer, no consent banner. |
lang=en |
Interface language. English today; the parameter is honoured so a second locale needs no snippet change. |
mode=ai |
Opens on the describe-it input rather than the item grid, for visitors more likely to type a sentence than fill a table. |
g=<id> |
Loads a specific saved calculation, so you can embed one worked example rather than an empty planner. |
What it costs, and the one condition
Nothing, and there is no view limit. The single condition is the attribution link in the snippet: keep it, keep it visible, and keep it a real link. That link is the entire price of the widget, and it is why there is no bill and no key to manage.
- Free, unlimited views
- Keep the attribution link
- Commercial sites welcome
Questions
Do my visitors have to sign up to use it?
No. A visitor can run a calculation without an account — that is the point of the embed. Signing in only matters if they want to save the result or run more than the free allowance.
Will it slow my page down?
The snippet sets loading="lazy", so the planner is not fetched until the visitor scrolls near it. Nothing is loaded on your page itself: no script, no stylesheet, no font.
Can I restyle it to match my site?
The frame follows your page width and honours the visitor's light or dark preference. Deeper theming is not available through the iframe — if you need the planner to look like your product rather than sit inside it, use the API and render the result yourself.
Can I remove the attribution link?
Not on the free embed — it is what pays for it. If you need an unbranded version, that is a licensing conversation rather than a no: get in touch.
Or try the full planner first
Same solver, with the history, exports and multi-container comparison the embed leaves out.
