Overview

Intlayer is an open-source internationalization (i18n) and content management framework designed for modern JavaScript applications. It allows developers to declare translations directly alongside their components in TypeScript or JavaScript, ensuring type safety, autocompletion, and validation while keeping client bundles lightweight.

The platform features a compiler that automatically extracts content to generate dictionary files, an AI-powered CLI tool to automate translations, and a visual editor for non-developers. It also includes a headless CMS with Live Sync capabilities, enabling hot updates without rebuilding.
