Why we made this free
If you write about nutrition, fitness or fast food, you've probably typed out a calorie table by hand — and then watched it go stale the next time a chain changed its menu. This widget is the alternative: your readers get a working calculator, and you never have to maintain a number again.
All we ask is that you keep the credit link in the snippet. That's the whole deal — no fees, no account, no strings.
Options
| What | How |
|---|---|
| Width | Set to 100% — it fills whatever container you drop it in. |
| Height | Pick one above, or set your own. Chipotle and Subway need the most room. |
| Auto-resize | Optional — see the snippet below if you want the iframe to grow to fit. |
| Lazy loading | Already on (loading="lazy"), so it won't slow your page down. |
Optional: auto-resize the iframe
The widget posts its height to the parent page. If you want the iframe to resize itself instead of using a fixed height, add this once, anywhere on the page:
Where the data comes from
Every number is cross-referenced from the chain's own published nutrition disclosures and verified before it ships. Where a chain only publishes regional or incomplete data — Subway's newer signature sandwiches, for instance — we say so on the page instead of guessing. If you spot something wrong, tell us and we'll fix it.
FAQ
Is it really free?
Yes. No signup, no API key, no usage limits, no fees. Keep the credit link and you're done.
Will it slow my page down?
No. It's a single lightweight iframe, lazy-loaded, with no ads, no tracking pixels and no external dependencies.
Can I use it on a commercial site?
Yes — blogs, publications, gyms, coaching sites, all fine.
Can I change the colours?
Not yet. If you need it to match your brand, email us — if enough people ask, we'll add a theme option.
Which chains are available?
Chipotle, Panda Express, Starbucks, Subway, Taco Bell and Chick-fil-A right now. McDonald's, Wendy's and KFC are next.
