Embed a free restaurant calculator on your site

Paste one line of HTML and your readers get a working calculator instead of a screenshot of one. 9 of them, all free, all running the same math as our tool pages.

Free, for any site

Commercial or not, one page or fifty. No account, no API key, nothing to sign. If it's useful to your readers, take it.

Keep the attribution

The caption line in the snippet is the price: a working link to the tool page and to Marji. Restyle it to match your type, but leave the links live and followed.

Nothing tracks your readers

The frame loads Marji's own code and nothing else. No Meta Pixel, no Google Analytics, no cookies, no third-party requests — the embed route ships a Content-Security-Policy that blocks them outright.

The math is the same math

The embed runs the identical compute function as the tool page, in the reader's browser. No numbers are sent to us, so nothing you or your readers type is stored anywhere.

Pre-filling an embed

Every input is readable from the query string, so you can open the calculator on the numbers your article is about. Writing about the 30% delivery commission on a $16 entrée? Point the frame at /embed/delivery-margin-calculator?menuPrice=16&commissionPct=30 and it opens there. The parameter names are the field keys shown on each tool page’s shareable link.
