Why Shopify Plus brands choose Checkout Components over Checkout Blocks.
Checkout Blocks is a free, Shopify-owned tool for content blocks, form fields, and Shopify Functions. It does not include upsells, third-party integrations, or revenue analytics. Checkout Components does, at flat pricing.

Free is misleading when revenue is missing.
Checkout Blocks does not include checkout upsells, cross-sells, post-purchase offers, or revenue analytics. To match what Checkout Components does, you'd add a separate upsell app on top.
Your tech stack, connected at checkout.
Checkout Blocks does not connect to any third-party applications. Checkout Components plugs the recommendation engines, review platforms, and identity tools you already use directly into the checkout surface.
Built to prove ROI.
Checkout Blocks ships with no analytics or reporting. Checkout Components shows AOV lift, conversion funnels, top-performing products, and component-level attribution in real time.
Independent, fast, merchant-led.
Checkout Blocks was acquired by Shopify in June 2024. Since then, independent feature work has slowed and the roadmap aligns with Shopify's broader platform priorities. Checkout Components is independently owned with a roadmap shaped by merchant feedback.
- Roadmap driven by merchant requests, not platform priorities
- Direct line to founders for Plus-tier accounts
- New features ship monthly, not quarterly
Test every change. Ship the winners.
Checkout Blocks has no built-in A/B testing, to test a change you'd need to wire up a third-party experimentation tool against the checkout. Checkout Components ships unlimited A/B tests on every plan, with component-level winner attribution baked in.
- Run unlimited concurrent A/B tests at checkout
- Automatic statistical significance + winner detection
- Test upsells, content, integrations, same tool
See every difference.
Their cost grows. Yours doesn't.

About Checkout Blocks, side by side.
Is Checkout Blocks free?
Yes, Checkout Blocks is free to install. But it ships with no upsell or cross-sell engine, no third-party integrations, and no revenue analytics, so the ROI of using it to grow your store is hard to measure or achieve.
Does Checkout Components support Shopify Functions?
No. Checkout Components handles personalisation through UI extensions and display rules. If you specifically need custom discount logic, payment-method filtering, or shipping-rate rules via Shopify Functions, Checkout Blocks is a great tool for that use case, and the two can run side by side.
Can I use Checkout Blocks and Checkout Components together?
Technically yes, but in practice most Checkout Components merchants replace Checkout Blocks. Checkout Components covers content, upsells, input fields, branding, and analytics, the full checkout customisation stack.
Why did Shopify acquire Checkout Blocks?
Shopify acquired Checkout Blocks in June 2024 to consolidate checkout customisation into its platform. Since the acquisition, independent feature development has slowed and the roadmap has aligned with Shopify's broader priorities rather than merchant-specific revenue goals.
Does Checkout Blocks have upsells?
No. Checkout Blocks does not include a product upsell engine. It is primarily a content, form, and Shopify Functions tool. To add product recommendations at checkout to lift AOV, you need a dedicated upsell app like Checkout Components.
How quickly can I see results with Checkout Components?
Mantle had their first upsell configured within 90 minutes of installing. Most merchants see measurable AOV lift within their first week. The average ROI across Checkout Components merchants is 22.7×.
