CheckoutStackFeatures
Everything here is shipped.
No roadmap items, no coming-soon badges. If it is on this page, it is in the app you install today.
Live preview while you type
The editor renders the actual block from the actual form state, inside a frame that mimics checkout. The countdown ticks in the preview. You are not reading a description of what will happen.
A/B testing and per-block analytics
Two variants, assigned at random per checkout and stable across every step. Checkouts reached, checkouts completed, conversion rate. A two-proportion z-test gates the winning label, and rates stay hidden below 20 checkouts.
Variables and light formatting
Drop the shop name, the buyer's first name, the item count, the cart total, the first product or the countdown into any text. Bold and links are supported. No HTML is ever parsed or injected.
Native image handling
Browse the store's Shopify Files or upload a new image from inside the app. Uploads land in the merchant's own Files library, so nothing is hosted by us.
Market and locale targeting
Limit a block to specific Shopify Markets, currencies, countries or languages. These come from Shopify's Localization API and need no extra permissions.
Nothing waits on us
Published blocks live in one app-owned Shopify metafield. The checkout extension reads that metafield and renders. Disabled blocks are stripped from the payload entirely, so they cost nothing.
The four block types
Banner
Title, body and four tones. Collapsible, dismissible, and an optional countdown that actually ticks down in the buyer's browser.
Reviews
Star ratings, verified badges, customer photos and reviewer avatars, in three layouts. Hide the long tail behind a read-more.
Trust list
Icon, headline and one line of copy, repeated. The reassurance list that sits under the pay button on every good checkout.
Image
Any image from the store's Files, with width, alignment, alt text and an optional link. Upload straight from the app.
Display rules
Every block can be limited by any combination of the fifteen fields opposite, matched on all or any conditions.
Rules are evaluated inside checkout from Shopify’s own signals, live. Add an item and a cart-total rule re-checks immediately. Change the shipping country and a country rule follows.
Shipping state or province, customer email and login state require Shopify’s protected customer data approval. Until that is granted they evaluate as empty. Everything else works on day one.

Wrap text in double asterisks for bold, or use markdown link syntax for a link. Anything a variable cannot resolve falls back to empty rather than printing the placeholder at a buyer.
Try it on your own checkout.
The free plan runs one block with every feature except A/B testing and analytics.
