About i18nexus

i18nexus is a hosted service for managing translations in React and Next.js projects. It manages strings for the next-intl, i18next and react-intl libraries and treats the shared workspace as the source of truth, with local translation JSON files generated from it instead of edited by hand.

Setup starts with a CLI command run inside the app repository, which creates an account and project, detects the i18n library, sets up languages and namespaces, and imports existing translations. A listener keeps local files synced as you build, and an MCP connection lets AI coding agents add or update copy through the platform. Translations can be generated with AI and then reviewed, edited and verified by the team before being synced back.

The product has API access, guides for React and Next.js with both the App Router and Pages Router, and a pricing page. Signing up is free and does not require a credit card, and there is no self-hosted edition of the service. The documentation also covers the REST API for teams that want to automate how translations are pulled into their builds.
