Comparison
T Lab alternative for Shopify: T Lab vs Unlost
T Lab is one of the highest-rated translation apps on Shopify, with generous product allowances. Where it differs from Unlost comes down to two things: when automatic updates kick in, and who pays for the AI.
We make Unlost, so read this with that in mind. Everything said about other apps comes from their own Shopify App Store listing and Shopify’s help center, checked on 7 October 2026. Prices and limits change; check the listing before you choose.
The short version
Stick with T Lab if you need images or third-party app content translated, have a very large catalogue, or are happy to manage your own API key on the Premium plan.
Unlost is the better fit if you want new and changed content translated automatically without moving to a top plan or managing API keys, and you want the text in your theme’s code translated too.
Where they really differ
Automatic updates. T Lab’s Autopilot, which translates new and updated content for you, is part of its $59.99 Premium plan. Unlost translates new and changed content within a minute on every paid plan, starting at $13.99.
API keys. T Lab’s Premium plan runs on your own DeepL, Google or ChatGPT key, which means a second account and a second bill. Unlost includes the AI in every plan, so there’s nothing to set up and nothing extra to pay.
Images and app content. Credit where it’s due: T Lab translates images and content from third-party apps. Unlost focuses on your store’s own texts, including text written into the theme’s code.

What Unlost translates
Pretty much everything a shopper reads: products with their variant options, collections, pages, blog posts, menus and policies; SEO titles, meta descriptions, URL handles and image alt texts; notification emails; your theme’s texts, including text written straight into the theme’s code, like a Custom Liquid block; and the metafields your theme shows.
All of it is saved in Shopify itself, so it stays in your store if you ever remove the app. Product names stay as you wrote them, short texts like buttons and sizes get an extra check, and anything uncertain goes to a review list. Edits you make yourself are never overwritten.
