Which one is for you
Pick Commerce Layer if
- Fits if you are a developer who wants checkout and order APIs behind your own front end
- Works for prototypes and small live stores under 100 orders a month
Look elsewhere if
- Skip it if you want a ready-made storefront, as there isn't one
- Tight if you outgrow 2 users, 2 markets or 1,000 SKUs, since the next step is a sales quote
- Not for you if you want a published price above the free plan
- Watch out: payment gateway fees are not included in Commerce Layer's per-order cost, and there is no on-premise version
Pick Nacelle if
- Fits if you run a Shopify store with large Meta ad spend
- Works for brands that want a control-group measurement of the extra sales
Look elsewhere if
- Not for you if you're not on Shopify, as Delta runs there
- Pricey if results are good, because 20% of proven extra revenue goes on top of $500
- Watch out: the pricing page says there is no lift data yet, and its examples are hypothetical
- Watch out: it isn't the headless platform Nacelle was known for
How we grade them
| 2.2GPACommerce LayerFair | 1.4GPANacelleWeak | |
|---|---|---|
| Value for money | BThe Developer plan is $0 with 1,000 SKUs and 100 free live orders a month, and Enterprise is a quote. Free but capped, with no published price in between. | D$500 a month flat plus 20% of proven incremental revenue, far above the category's $29 middle, and the cost grows with results. |
| Free plan and trial | BDeveloper plan: 1 organization, 2 users, 2 markets, 1,000 SKUs, unlimited test orders and 100 live orders a month, which a small project could live on. | DNo free plan or trial on record. The pricing page says billing starts only after the first lift report, but gives no length. |
| Features | CCheckout, order management, markets, price lists and promotions through APIs. The listing shows a gap: no built-in storefront, so a front end has to be built or bought. | DOne narrow job, an ad-matched storefront with a shopping assistant, on top of Shopify. It isn't a store platform. |
| Ease of use | DNo store rating on record. It is an API platform that developers must build on. | CNo rating on record. It's a one-click install, but needs read-only access to your Meta ad account. |
| Platforms and integrations | CWeb platform with a core API and MCP access. No desktop or phone app, and no integrations listed. | CWeb only, working with Shopify and Meta. |
| Best for | developers building their own storefront | Shopify stores spending heavily on Meta ads |

Worth knowing
Commerce Layer
- It is an API platform with no built-in storefront, so a front end has to be built or bought separately.
- The Developer plan is capped at 2 users, 2 markets and 1,000 SKUs; above that, pricing is custom through sales.
- Payment gateway fees are not included in Commerce Layer's per-order cost.
- There is no on-premise version, and no trial period outside the free Developer plan.
Nacelle
- Pricing is a $500 monthly platform fee plus 20% of measured incremental revenue, so the cost grows with results.
- The pricing page says there is no lift data yet; its examples use hypothetical lift chosen by the reader.
- Delta runs on Shopify and is built around Meta ads; the page lists questions about TikTok, Google and non-Shopify stores without answers visible in the page text.
- This is no longer the headless commerce platform Nacelle was known for; the site mentions a few large brands still running on it.
Key features
Commerce Layer
- Universal checkout API
- A stateless checkout that handles multiple markets and currencies and connects to the payment gateway and tax calculator a team picks.
- Distributed order management
- Tracks inventory across locations and covers the order lifecycle from reservation to shipment. Sold as an add-on to the Enterprise plan.
- Promotion engine
- Market-specific promotion rules set in a visual editor or a JSON-based rule language. Also an Enterprise add-on.
- Markets and price lists
- A market ties together a merchant, an inventory model and a price list, so one organization can sell in several regions or business models.
- Shoppable links
- Links turn a SKU or set of SKUs into a small storefront that can be shared by email, SMS or messaging apps without building a full site.
- Metrics and provisioning APIs
- The Metrics API pulls order, return and cart history for custom reports; the Provisioning API automates account and credential setup.
Nacelle
- Ad-matched storefront
- Delta reads the Meta ad a shopper came from and reshapes the homepage, collection and product pages and recommendations around that ad's message.
- Paige shopping assistant
- An AI shopping assistant trained on the store's catalog answers questions about products, shipping and returns, and knows which ad brought the shopper.
- Control-group measurement
- A control group on the same store measures what Delta added. The performance fee is billed on the lower bound of that measured range.
- One-click install
- Delta installs as a Shopify app with no theme edits, works with the existing theme, and can be set back to zero exposure.
- Read-only Meta access
- Delta reads campaigns, creative and Meta's performance data per asset; the site says it never edits a campaign, budget or creative.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
