Per-component Internationalisation solution for JS application. Type-Safe. Translate with AI. Edit Visually.

What it solves

Intlayer addresses the complexity and rigidity of traditional internationalization (i18n) libraries. It simplifies the process of making web and mobile apps multilingual by providing a toolset that integrates AI-powered translation, a visual editor, and a CMS, reducing the manual effort required to manage translations across different frameworks.

How it works

Intlayer uses a per-component content declaration approach where translations are kept close to their respective components (1 component = 1 dictionary). A dedicated compiler extracts content from these components and generates dictionary files. It supports TypeScript for type-safety and autocompletion, and uses tree-shaking and dynamic loading to ensure that only the necessary content is loaded, optimizing the final bundle size.

Who it’s for

Developers using modern web frameworks like Next.js, React, Vite, Vue.js, Nuxt, and Preact, as well as Express for backend services, who need a scalable and maintainable way to handle internationalization.
