AutoLingo vs Weglot vs Native translation
May 2026 · 9 min read
Running a multilingual PrestaShop store? This comparison covers the three main approaches — an API-powered back-office module, a SaaS overlay, and the built-in native translation — with honest trade-offs on price, data privacy, quality and automation.
For most stores that want automatic translation with full control over quality and cost, AutoLingo is the best choice. Weglot is faster to set up and works well for small catalogues, but the subscription cost compounds quickly as your word count grows. Native PrestaShop translation is free but entirely manual — viable only for very small catalogues.
The three approaches
AutoLingo — back-office API
A PrestaShop module that connects your store to DeepL, Google or OpenAI using your own API key. Translation happens in the back-office — names, descriptions and meta fields are written directly into the PrestaShop language rows. $39.99 a year with no word limits; cancel and the installed module keeps working.
- ✓Flat $39.99/yr — not tied to word count
- ✓Your own API key — full cost transparency
- ✓Data goes directly to DeepL/Google/OpenAI
- ✓Translations stored natively in PS DB
- ✓Auto-translate on save + manual panel
- ✓Four providers
- ✓Translation log in the back-office
- –Requires an API key
- –No visual front-end editor
- –Newer module
Weglot — SaaS overlay
A subscription SaaS that injects a JavaScript snippet. It intercepts rendered pages, sends text to Weglot’s servers (DeepL/Google under the hood), caches it and serves translated versions via subdomain or subdirectory. From €15/month for 10,000 words.
- ✓Fastest setup (minutes)
- ✓Translates everything visible — no gaps
- ✓In-context visual editor
- ✓No API key to manage
- ✓Works with any PS version/theme
- –Subscription — cost grows with word count
- –Content routed through Weglot servers
- –Translations stored in Weglot, not your DB
- –Stops working if subscription lapses
- –JS overhead on every page
Native PrestaShop
PrestaShop has built-in multilingual support: every product, category and CMS page has a language tab where you type translations manually. There are no automatic features — everything is entered by hand.
- ✓Completely free
- ✓No third-party dependency
- ✓Full control over every word
- –100% manual — no automation
- –Scales very poorly (100+ products = hundreds of hours)
- –No quality check or translation log
Translation quality
All three options can achieve high-quality translations for e-commerce content — the differences are in how they get there.
Which AI engine?
AutoLingo lets you pick: DeepL (European languages), Google Translate (broadest coverage) or OpenAI GPT-4o mini (nuanced product descriptions). You pay the provider directly at their published rates. Weglot uses DeepL and Google under the hood but routes requests through their servers, adding a cost layer — and you don’t choose which engine is used.
HTML preservation & meta fields
AutoLingo sends content in html format (tags stay intact) and translates every translatable field per product: name, description, short description, meta title and meta description, written to the correct row in ps_product_lang. Weglot translates what it sees on the rendered page — a field not visible in the front end will not be translated.

Pricing
The cost gap compounds fast. A store with 500 products (≈200 words each) = 100,000 words. With Weglot you’d pay €79/month (Business). With AutoLingo: $39.99 a year + ≈$2.87 in DeepL credits for the initial translation. Even Weglot Starter (€15/month, €180 a year) costs more than a full year of AutoLingo by month 3 — and only covers 10,000 words.
Data privacy
This is where the two automated approaches differ most sharply.
AutoLingo
Your content is sent directly from your server to the API you configured. It never touches AutoLingo’s infrastructure. The translated text is written into your PrestaShop database. If you cancel your API key tomorrow, all your translations remain in your database, intact.
Weglot & GDPR
Your content is routed through Weglot’s servers, translated, cached on their CDN and served from their infrastructure. If the subscription lapses, translated pages stop being served — a genuine lock-in risk under data-residency requirements. If your descriptions contain personal data, routing through a third-party SaaS requires a DPA with that SaaS.
Who should use AutoLingo
AutoLingo is the right choice if…
- ✓Your catalogue has more than a few dozen products — the flat price pays off quickly
- ✓You want translations stored natively in your DB — no lock-in
- ✓You need meta fields translated for SEO, not just visible text
- ✓You want to choose your provider and pay them directly — no markup
- ✓Compliance means content must not leave your infrastructure
- ✓You want OpenAI for complex product descriptions
Weglot is the better choice if…
- ✓You need translations live within the hour, zero config
- ✓Your catalogue is small (< 10,000 words) and stays in Starter
- ✓You need an in-context visual editor for your team
- ✓You want to translate the whole store (theme, modules, checkout) without mapping fields
Native PS is the right choice if…
- ✓Your budget is strictly zero
- ✓Your catalogue has fewer than ~20 products and manual is fine
- ✓Translation quality must be human-reviewed before going live
Final verdict
AutoLingo is the best value for any store planning to stay multilingual long term. The flat $39.99 a year means you’re not locked into a fee that grows with your catalogue. Translations live in your own database, work with any theme and survive provider changes.
Weglot earns its place for stores that need to go multilingual today with minimal technical effort, or that value the in-context visual editor. Just model the long-term cost before committing.
Bottom line: if you translate more than 50,000 words and want to own your data, AutoLingo pays for itself in a single month versus Weglot Business. For rapid zero-config setup on a small catalogue, Weglot wins. For zero budget, native PS in manual.
