Locize: sovereignty score and 8 European alternatives

Locize is a localisation platform that connects an application's i18n setup to translators and delivers translation updates continuously. It is built by the creators of the open-source i18next library but works with other i18n libraries too. Keys are synced from the codebase through a CLI, CI or direct integration. Translators work in a dedicated interface with an in-context editor, glossaries and AI-assisted translation, using Locize AI or the customer's own LLM keys. Role-based access, review steps, quality checks and an audit trail are included. Translations are published through a CDN or API, so updates need no full redeploy.

Locize is operated by inweso GmbH, a Swiss company based in Altnau. Switzerland is outside the EU but in EFTA. Its privacy policy states that the application and customer data are hosted in Ireland by Amazon Web Services, with encrypted disaster-recovery copies on EU-based BunnyCDN storage. Published translations on the Pro CDN may be cached at edge locations in the United States and worldwide. Locize itself is a commercial hosted service, not open source.

Why digital sovereignty matters with Locize

Locize is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Data is hosted exclusively in the EU, so Locize scores best on data residency.

Locize is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Locize together with your other vendors and gives a total score, a heatmap and the main risk drivers.
