Get Started

Test Any Product

Is your product ready for your target markets? We offer localization testing for web, mobile, software, and hardware.

Guaranteed Quality

We verify the accuracy, consistency, and overall quality of your localized product with your target audience.

Reliable Usability Testing

Linguistic and functional testing go hand in hand. We take care of both.

Our Localization Testing Services

Localization testing is an integral step of any localization task—whether it’s for web, mobile, or software localization.

Our localization team will perform functional, linguistic, and cosmetic validation to test your product inside out. Our goal: to bust the bugs before your users do.

Why is localization testing necessary?

Localization testers verify that your localized content is linguistically correct, culturally appropriate, and that it fits within the context. They examine the functionality of your product to ensure proper operation on localized operating systems and supported platforms.

Localization QA testers are the very first people to see the translated or localized product in context and are therefore the only people who can verify its consistency, accuracy, and overall quality.
