SiteTran runs as a small Widget Code in your Stencil theme's base layout. BigCommerce keeps rendering your store as usual, and SiteTran shows each shopper their language.
Sign up free and create a site for your store. SiteTran gives you your Widget Code, which adds the language dropdown to your storefront.
Open your theme's files, then paste the Widget Code into templates/layout/base.html right before </body> and save and apply the file.
Open your store and pick a language. SiteTran discovers your text as you browse, then you translate it with AI, your own translators, or both, and publish.
<script>var sitetran = {site_id: your_site_id};</script> <script src="//c.sitetran.com/widget/v3.js"></script> <div id="sitetran_translate_element"></div>
SiteTran gives you your own ready-to-paste code, with your site ID already in it. The div is where the language dropdown appears.
base.html before you apply it.<script> tags, and the Widget Code also has a div that places your dropdown. One file keeps all three lines together.Stencil storefronts load a lot after the first page view: filtered results, quick view, the cart preview. Here's how SiteTran handles each part of a BigCommerce store.
When a shopper ticks a filter, sorts or pages through a category, Stencil themes swap in new results without a full reload. SiteTran watches the page and translates them as they appear, along with filter names and values from your product options.
These open in modals and dropdowns that load after the page. SiteTran translates them when they open, so a shopper can browse, compare and add to cart without leaving their language.
Text, button and HTML widgets you drop in with Page Builder render on the page like the rest of your theme, so they're translated too. So are web pages such as Shipping & Returns and your blog posts.
Option labels like Size and Color are translated as phrases. For messages where a number changes, such as bulk pricing tiers or "Only 3 left", turn on Automatic Number Variables so one translation covers every value.
Your catalog, price lists and currency conversion keep running in BigCommerce, and the currency selector works as before. SiteTran translates the words around your prices and never writes back to your products.
Text that apps add to your storefront is translated like any other text. With Multi-Storefront, add the Widget Code to each storefront's theme. B2B Edition's Buyer Portal has its own translation settings in BigCommerce.
SiteTran loads from your theme's base layout, so every page built on it is translated, from the home page and filtered categories to the cart and My Account.

Shoppers browse categories, filter results, open quick view, read reviews and check their cart in their own language, so nothing gets lost before they decide to buy.
Account pages are translated too, and you choose which personal details, such as addresses and order history, stay exactly as written.
Like every storefront translation tool, checkout, order confirmation and order emails use BigCommerce's own language settings. BigCommerce's checkout comes pre-translated into English, French, German, Italian, Norwegian, Polish, Portuguese, Spanish, Swedish, Danish and Dutch, and shows your storefront's language. Your theme's language files can add or adjust checkout text.
To show each shopper checkout in their own language, BigCommerce's multi-language storefronts cover checkout and order emails. Book a call and we'll help you plan checkout for your markets.
BigCommerce made multi-language storefronts generally available in August 2026, and the App Marketplace has translation apps that work very differently. Here's what each approach involves.

|---|---|---|---|---|
| How it works | You add a translation for each product, category and setting in the Translations Manager, or send them with the GraphQL Translations API. | The app serves translated copies of your pages, usually on language subdomains such as fr.yourstore.com, set up with DNS records. | A widget sends the page to Google's machine translation in the shopper's browser. | SiteTran translates your storefront as it renders in the shopper's browser, using translations you control. |
| What's covered | Catalog, categories, brands, navigation, checkout, emails and more. Theme text comes from your theme's language files. | Storefront pages. Checkout depends on the app and on BigCommerce's checkout script rules. | Visible text on pages where the widget loads. | Every page on your base layout, including filters, quick view, Page Builder widgets, blog and app content. |
| Who translates | You or your team, field by field. BigCommerce lists AI-assisted translations as coming later. | Machine translation, then manual edits or paid human translation. | Google machine translation only. | DeepL, Google Translate or OpenAI, plus your own translators and reviewers. |
| Languages | Up to five per storefront. | 100+, with language counts tied to plan. | 100+. | 187+, unlimited on every plan. |
| Language URLs for SEO | Yes: language subfolders, translated product URLs and language sitemaps. | Yes, on subdomains or subdirectories, often on higher plans. | Usually no. | Same URLs by default. Language URLs through the Static Translation API and a proxy. |
| Changes to your store | Turn on languages. The language selector needs a recent theme, such as Cornerstone 6.19.0 or newer. | Install the app and add DNS records per language. | Install the app. | Paste the Widget Code once. No DNS or catalog changes. |

A BigCommerce catalog can hold thousands of product names, option labels and descriptions. Start with machine translation, refine with your own team, and decide what goes live.
Get suggestions for any phrase, or translate new phrases automatically as shoppers find new products. You choose whether they're approved automatically or reviewed first.
Invite your own translators, or your distributor in each market, and choose who can approve. Turn on AI Translation Review for a second opinion on each translation.
Lock brand names and technical terms in the Glossary, set Translation Rules that AI translation follows, such as formal "Sie" in German, and reuse past work with Similar Phrases.
Choose from three dropdown types, with or without flags, and add your own CSS so it sits neatly beside your currency selector. Shoppers are switched to their browser language automatically.
Here's what's translated as soon as you install SiteTran, and how to give each language its own indexable URL on BigCommerce.
SiteTran translates more than visible text. When a shopper switches language, the page's metadata switches with it.
lang attribute, set to the selected languageBy default, every language uses your store's existing URLs and the shopper's choice is remembered. For a separate, indexable page per language, SiteTran's Static Translation API returns translated HTML for URLs like these:
These pages are served by a proxy or edge worker in front of your storefront. BigCommerce's own language subfolders are another route, using translations stored in BigCommerce. We'll help you choose.

Six BigCommerce-specific checks that separate a translated store from one that sells in that language.
SiteTran discovers text when it's shown. Tick each filter, open quick view and the cart preview, run a search and trigger your pop-ups once, or turn on Machine Translation Auto Translate so new text is translated as shoppers find it.
Recent Stencil themes show their own language selector when BigCommerce languages are turned on. Pick one approach, and position SiteTran's dropdown with CSS next to your currency selector.
Add brands and product lines to the Glossary. In your theme templates, add translate="no" to SKUs, part numbers and anything that must never change.
My Account shows addresses and order history. Exclude those elements with sitetran.ignore_selectors, or turn off Public Phrase Discovery for stores with sensitive data.
German and French filter labels and buttons run longer. Add CSS per language where a label wraps, and swap carousel images that have English text baked in.
Place a test order in each language you launch and confirm checkout reads the way shoppers in that market expect, adding BigCommerce's checkout translations where you need them.
Most setup problems come down to which theme was edited, a security setting, or a translation that isn't live yet.
