What your shoppers get
- A small compare button in the corner of every page, and one on each product tile.
- On a product page: "Add this product" — the widget reads the name, price, stock and picture straight off your page.
- On a category or search page: tick the products they want from a list of what is on the page.
- A search of your catalogue by name, on Shopify and WooCommerce. On other platforms shoppers add products by tapping them on the page.
- A plain-language verdict, a side-by-side table of ten or more attributes — including the problems owners most often report — and a chat that answers follow-up questions about those products.
- Their list stays with them from page to page. Nobody has to sign in.
One line to install
Paste this before the closing </body> tag of your site, with the key we give you in place of YOUR-KEY:
<script src="https://widget.compareio.website/widget.js" data-site="YOUR-KEY" async></script>On Shopify: Online Store → Themes → Edit code → theme.liquid, just above </body>. On WordPress / WooCommerce: any "header and footer scripts" plugin, or your theme's footer. On Wix: Settings → Custom code. On Squarespace: Settings → Advanced → Code injection. On BigCommerce: Storefront → Script manager. On Magento or PrestaShop: your theme's footer template. The widget loads after your page, never before it, and adds nothing to your page weight until a shopper taps it.
Built for a store, not against it
- The comparison is built from your product data plus the manufacturers' published specifications. It never searches other shops, never mentions another retailer, never shows another price. The panel says so, in writing, under every verdict.
- Comparisons made on your store are private to your store: they are not published on compare⁄io, not listed, not indexed by search engines.
- No cookies are set on your site and nothing about the shopper is collected. The shopper's list lives in their own browser.
- The widget cannot read or change anything on your page beyond the product information every shop already publishes for Google. It draws its button, and that is all.
- Your colour, your corner: the button takes your brand colour and sits left or right, as you prefer. The per-tile buttons can be switched off.
What it costs
Your shoppers pay nothing and never need an account. The widget is available now as a lifetime deal on AppSumo: you pay once, and your plan gives you a number of comparisons every month, for good. Repeats of the same comparison are free and are not counted.
| Plan | Comparisons |
|---|---|
| AppSumo 2,000 | 2,000 a month, refilled on the 1st, for good |
| AppSumo 5,000 | 5,000 a month, refilled on the 1st, for good |
| AppSumo 10,000 | 10,000 a month, refilled on the 1st, for good |
Need more in a busy month? Extra credits will be on sale from your dashboard — one credit is one comparison, and they never expire: 1,000 for $9, 5,000 for $35, 10,000 for $59.

Questions people ask
Does it work with Shopify?
Yes. Shopify stores get the most out of it: the widget reads Shopify's own product data (real price, variants, stock, vendor) and lets shoppers search your catalogue by name from inside the panel. Stores selling in several countries are handled — shoppers see the price in the currency your store is showing them, not your home one.
Does it work with WooCommerce?
Yes, and it does not care where your products live: if you have changed your product address from the WooCommerce default, or WordPress sits in a subfolder, it still finds them. WooCommerce stores also get catalogue search by name inside the panel.
Does it work with Magento, BigCommerce, PrestaShop, Wix, Squarespace or a custom-built store?
Yes — each of those is recognised by its own product markup, so the compare button appears on your product tiles without any setup. Shoppers add products by tapping them on the page rather than searching a catalogue, which is what most people do anyway. Anything else that publishes the standard product information Google reads (structured data or Open Graph tags — nearly every store does) works too.
My theme is unusual — what if it does not find my products?
Tell us and we will set it up for your theme. It is a one-off change on our side, at no charge, and it usually takes minutes: we ask you to run one line in your browser's console, which tells us exactly what your tiles look like.
Will it slow my site down?
No. The line loads a small script after your page has finished, and the panel itself is only fetched when a shopper taps the button.
Where do the facts in the comparison come from?
From your product pages first — name, price, availability, description, brand — and from the manufacturers' published specifications for the rest. No web search runs, so nothing comes from other retailers. Each verdict says this underneath.
Can shoppers see comparisons made on other stores?
No. Every store's comparisons are its own, and they are never published or listed anywhere.
Can I turn it off?
Remove the line, or switch the widget off on your business dashboard. Either takes effect within about five minutes.
What happens when my allowance runs out?
Any extra credits you have are used next, one per comparison. With none left, the button stops offering new comparisons until the month turns over. Nothing else on your site changes, and nothing breaks — a shopper who taps it is simply told it is unavailable.
