Built for engineering teams who are measured on conversion.
A data layer for teams that own their storefront and are judged on what it converts. It is not a no-code tool and it does not pretend to be.
Your front end stops making live platform calls on every page load. It reads from an index built for the job, which is where the speed comes from.
What it is.
Nacelle sits between Shopify and your storefront and indexes your product, collection and content data into a fast, queryable layer.
You build the storefront, in whatever framework your team already runs. Nacelle makes it fast enough to be worth building.
What it produces.
Speed is not a vanity metric in ecommerce. It is the most reliable conversion lever there is, and it compounds as mobile grows as a share of traffic.
FTD, one of the largest floral commerce businesses in the world, runs its storefront on Nacelle.
Results depend on the storefront you build. Nacelle removes the platform as the bottleneck. What you do with that headroom is your team's work.
What it costs you
Honesty, because this is the part most vendors skip. A headless storefront is a real engineering project. It needs front-end engineers who own it, a build and deploy pipeline, and a team willing to maintain a storefront rather than install a theme.
Brands that do this well are usually large enough to have an engineering function with a mandate to improve conversion, and they treat the storefront as a product rather than a marketing asset.
If that is not your team, this is the wrong tool, and we will tell you so on the first call.
Who it is for
- Ecommerce teams with in-house front-end engineering
- Brands where conversion rate is an engineering KPI, not just a marketing one
- Storefronts complex enough that a theme has become the constraint
- Teams already running or seriously evaluating a custom front end
Nacelle Headless is a live product in production at scale, including at FTD, and it is fully supported. Nacelle's current focus is Delta, our post-click optimization product for Shopify, but Headless is not going anywhere and existing customers are supported as they always have been.

If you have a front-end team and a conversion mandate, we will tell you honestly whether this is worth your time.
