- 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
Pick VTEX if
- Fits if you run several storefronts or countries and have a team to roll out a platform
- Works for distributors adding B2B ordering or retailers opening a marketplace to outside sellers
Look elsewhere if
- Skip it if you want to see a price before talking to anyone, because none is published
- Not for you if you're a small shop: it's aimed at mid-size and large merchants
- Tight if you need a free plan or a trial, as neither is listed
- Watch out: customer service and retail media are sold as separate products, not part of the commerce platform
How we grade them
| 1.4GPANacelleWeak | 2.0GPAVTEXFair | |
|---|---|---|
| Value for money | D$500 a month flat plus 20% of proven incremental revenue, far above the category's $29 middle, and the cost grows with results. | CNo price is published, so we can't place it. The get-started page leads to a sales conversation, which is what a platform for large merchants usually does. |
| Free plan and trial | DNo free plan or trial on record. The pricing page says billing starts only after the first lift report, but gives no length. | FNo free plan and no self-service trial are listed on the pages we read. |
| Features | DOne narrow job, an ad-matched storefront with a shopping assistant, on top of Shopify. It isn't a store platform. | BD2C, B2B and marketplace selling, order routing across warehouses and stores, multi-store and multi-currency. Nothing in the listing is missing from an enterprise store's core job. |
| Ease of use | CNo rating on record. It's a one-click install, but needs read-only access to your Meta ad account. | CNo app-store rating on record. It's a platform you roll out with VTEX's team rather than sign up and start. |
| Platforms and integrations | CWeb only, working with Shopify and Meta. | BWeb platform with a WhatsApp shopping flow, hundreds of ready-made apps and an API for your own extensions. No desktop or phone apps listed. |
| Best for | Shopify stores spending heavily on Meta ads | large merchants selling in several countries |

Worth knowing
Nacelle

- 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.
VTEX
- No prices are published; the get-started page leads to a conversation with a VTEX solution engineer.
- The platform targets larger merchants, and the pages we read list no free plan or self-service trial.

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.
