What is Intlayer?

Most i18n libraries are either too complex, too rigid, or not built for modern frameworks.

Intlayer is a modern i18n solution for web and mobile apps.
It’s framework-agnostic, AI-powered, and includes a free CMS & visual editor.

With per-locale content files, TypeScript autocompletion, tree-shakable dictionaries, and CI/CD integration, Intlayer makes internationalization faster, cleaner, and smarter.
