In their own words
i18nexus
i18nexus is a web and API localization workspace for developers, AI agents, and teams handling application copy. Developers can manage translations through a REST API, CLI syncing, and an MCP interface for AI coding agents. The CLI imports existing local JSON files, synchronizes them during development, and retrieves translations before production builds. A shared dashboard lets developers, product managers, translators, and other members review, edit, and verify translations. The service supports more than 100 languages, translation history, and versioning. It highlights React and Next.js integrations with next-intl, i18next, and react-intl, while also supporting frameworks that consume JSON files. Machine translation can use OpenAI, DeepL, or Google Translate, depending on the plan. Listed plans provide unlimited projects, languages, and translators, while string and member counts are limited. Plans also impose monthly machine-translation character limits. A free plan is available; paid plans start at $14/mo.
