BigCommerce vs Nacelle (2026): which should you pick?

Pick BigCommerce if

• Fits if you want discount types and shipping rules built in rather than added as apps
• Works for selling on Amazon, eBay and Walmart from one catalog

Look elsewhere if

• Tight if your sales are growing, as passing $30K a year moves you up to Growth at $79 a month
• Pricey if you want abandoned-cart emails, customer groups or stored cards, which start on Growth at $79 a month
• Watch out: paying through a provider outside BigCommerce's list adds 2% a sale on Core and 1% on Growth
• Watch out: Scale covers $33,333 of sales a month and charges 0.9% on anything above it
• Skip it if you want a free plan, as there's only a 15-day trial

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

BigCommerce

• Each plan caps sales over the past twelve months (gross order value minus 10%); passing $30K on Core or $100K on Growth moves the store up a plan.
• Orders paid through providers outside BigCommerce's embedded list carry a fee of 2% on Core, 1% on Growth and 0.6% on Scale.
• Scale covers $33,333 of sales a month and charges 0.9% on sales above that.
• Customer groups, abandoned-cart emails and stored cards need Growth or higher, and product filtering needs Scale.

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.

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.
