Is Phrase or Transifex better for software localization?

Phrase (formerly Memsource) is better for professional localization teams and translation agencies who need a full CAT (Computer-Assisted Translation) tool with TM, glossary, and quality assurance. Transifex is better for developer-centric localization with strong CLI/API integrations and community translations. Transifex's developer workflow is more streamlined; Phrase's translation tools are more professional.

What happened to Memsource — is it now Phrase?

Yes — Memsource rebranded to Phrase in 2022 after acquiring the Phrase Strings platform. Phrase now offers both a TMS (Translation Management System, formerly Memsource) and Phrase Strings (developer-focused localization). The combined platform competes more directly with enterprise TMS solutions. Existing Memsource customers continued on the same platform under the new Phrase brand.

Frequently Asked Questions

What file formats do Phrase and Transifex support?

Both platforms support the most common localization file formats: JSON, YAML, PO/POT (gettext), XLIFF, iOS strings, Android XML, and more. Phrase (formerly Memsource) supports a broader range including Microsoft Office documents, DITA, InDesign IDML, and other complex document formats — reflecting its origin as a professional translation tool for agencies. Transifex focuses on software-centric formats. For document translation beyond software, Phrase has the advantage.

Does Transifex work with React i18n?

Yes — Transifex has native support for React localization through its Transifex Native SDK, which provides an over-the-air translation delivery system specifically for React apps. This means you can update translations without deploying a new version of your app. Phrase also integrates with React through its CLI and file-based approach. Transifex's React-native SDK is a differentiator for teams that want real-time translation updates in their React applications.
