Locize
The native translation backend for i18next·locize.com
Locize is a cloud-based localization and translation management platform that connects developers, translators, and product teams. It lets teams manage translation keys from code, translate and review them in a dedicated UI, and deliver updates via CDN/API without requiring an app redeploy. It is built by the creators of the i18next JavaScript internationalization library and integrates natively with i18next as well as other i18n frameworks, file formats, and CI/CD pipelines.

Pricing
All fixed plans are billed monthly with no annual pricing shown. All plans, fixed or usage-based, include a 14-day free trial with full feature access and no credit card required. Overage blocks are tiered and get cheaper at higher cumulative volumes; on Enterprise you can buy extra download blocks, on other fixed plans you upgrade to the next tier; the Free plan auto-unpublishes translations instead of blocking when over its limit. The Usage-Based plan has a $5/mo base fee plus usage-based costs with no seat/namespace/language limits.
