One click on Shopify. One script tag anywhere else.

Reviews, loyalty and wishlist widgets for Shopify, Next.js and headless stores. Shopify gets a native app with theme blocks, and everything else gets a script tag and an API.

Shopify, without the setup chores.

Connect your store and your data comes across and stays in sync. The widgets go on from the theme editor you already know.

  1. Step 1

    Connect the store.

    One OAuth approval, started from Shopify or from Meisei. Meisei registers its webhooks and starts the backfill on its own.

  2. Step 2

    Your data arrives.

    Products, customers and orders sync in, and the webhooks keep them current from then on. Review requests can be going out the same day.

  3. Step 3

    Widgets go on the theme.

    The theme app extension adds the review and loyalty widgets as blocks in Shopify's own theme editor, with deep links that take you straight to the right spot.

Widgets that match your storefront.

Every widget is styled through CSS custom properties with neutral defaults. A theme editor with a live preview changes them, and your own custom CSS can restyle anything else, with a version history to go back through.

If you don't write CSS, describe the look you want and Meisei's AI writes the stylesheet against the widget's real markup.

The whole install, on any storefront

<script src="https://cdn.meisei.example/embed.js"

<div data-meisei-reviews="classic-tee"></div>

No platform needed.

Meisei was designed around the custom storefront, so nothing here depends on a platform.

Script-tag widgets
Reviews, loyalty and wishlists render from one script tag and a publishable key. If your storefront serves HTML, they run on it.
The REST API
Headless builds skip the widgets and read the same API the dashboard uses. Our example store is a plain custom storefront that integrates through the public API alone.
CSV that matches your old app
Imports read a Yotpo, Judge.me or Okendo export unchanged. Pick the format and upload the file the other app gave you, with no column-mapping spreadsheet in between.
Webhooks out
Meisei sends each change to your systems as it happens, whatever your stack.

Questions, answered.

Which platforms does Meisei work with?

Shopify has a native app. Any other storefront, including WooCommerce, BigCommerce, Next.js and custom builds, adds the widgets with a script tag and connects its data through CSV or the REST API.

Does Meisei work with Klaviyo?

Yes. Meisei sends review, loyalty and wishlist events and profile properties to Klaviyo, so you can use them in your own flows.

Can I style the widgets to match my store?

Yes. Adjust colors and fonts in a live theme editor, write your own CSS with a version history, or describe the look you want and let AI write the CSS for you.

Does Meisei support Next.js?

Yes. The React widgets render on the server in the Next.js App Router, so reviews are in the HTML the server sends. That includes Vercel Shop, Vercel's Shopify storefront template, which takes the widgets with no mapping at all.
