Embed our cost calculators on your site

Free to use on any site, including commercial ones. No signup, no API key, no tracking scripts on your page. The only condition is that you keep the attribution link.

Why you might want one

Both calculators answer a question vendor pricing pages avoid: what the tool costs once you add the billing unit that is charged on top. WhatsApp platforms quote a subscription and leave out Meta's per-conversation fee. Automation tools quote a plan and leave out the fact that a Zapier task, a Make operation and an n8n execution are not the same amount of work. If you write about these tools, the calculator does that arithmetic for your reader inside your page.

We keep the numbers current — every figure is checked against the vendor's own pricing page and dated. When a vendor changes price, your embed updates with it. Nothing to maintain on your end.

WhatsApp API Cost Calculator

Subscription plus Meta's per-conversation fee, which platform pricing pages leave out. The reader enters the Meta rate for their own country.

Workflow Automation Cost Calculator

Zapier, Make and n8n on the same volume, each priced on the cheapest plan that actually covers it — task vs operation vs execution included.

Making it resize itself

The iframe ships with a fixed height that fits most layouts. If you would rather it match its content exactly, the widget posts its height to the parent window — add this once, anywhere on the page:

<script>
window.addEventListener("message", function (e) {
  if (!e.data || !e.data.stackpick) return;
  document.querySelectorAll('iframe[src*="trystackpick.com/embed/"]').forEach(function (f) {
    if (f.contentWindow === e.source) f.style.height = e.data.height + "px";
  });
});
</script>

Terms, in plain words

• Use it on as many pages and sites as you like, commercial included.
• Keep the attribution link in the snippet. That link is the whole price.
• Do not alter the numbers or re-host the widget on your own domain — if the figures drift from what we verified, the attribution stops being honest.
• We load no cookies and no analytics inside the frame, so it will not complicate your consent banner.

Some links inside the widget point to tools we have an affiliate relationship with. That never changes the ranking: rows sort by price, computed in your reader's browser from the same public figures we publish on our pricing index. Full detail in our how we make money page.
