Documentation · Website · Blog --- ## Why Better i18n? Most localization tools weren't built for modern developer workflows. Better i18n is different: - **GitHub-native** — translations sync as PRs, reviews happen in your existing workflow - **CDN-delivered** — translations served from [Cloudflare's edge network](https://cloudflare.com), updated without redeployment - **AI-powered** — context-aware translation with [Google Gemini](https://deepmind.google/technologies/gemini/), not word-by-word machine output - **TypeScript-first** — full type safety across [Next.js](https://nextjs.org), [React](https://react.dev), [Expo](https://expo.dev), and [React Native](https://reactnative.dev) - **MCP-ready** — AI agents can manage translations through the [Model Context Protocol](https://modelcontextprotocol.io/) ### How it compares | Feature | Better i18n | [Crowdin](https://crowdin.com) | [Lokalise](https://lokalise.com) | [Phrase](https://phrase.com) | |---------|:-----------:|:------:|:--------:|:------:| | GitHub-first workflow | ✅ | Partial | Partial | ❌ | | AI translation with context | ✅ | ✅ | ✅ | ✅ | | CDN delivery (no redeploy) | ✅ | ❌ | ❌ | ❌ | | TypeScript SDKs | ✅ | ❌ | ❌ | ❌ | | MCP server for AI agents | ✅ | ❌ | ❌ | ❌ | | CLI scanner (unused key detection) | ✅ | ❌ | ❌ | ❌ | | ICU MessageFormat support | ✅ | ✅ | ✅ | ✅ | | Open-source SDKs | ✅ | Partial | ❌ | ❌ | | Free tier | ✅ | ✅ | ❌ | ❌ | ## Packages | Package | Description | Version | |---------|-------------|---------| | [`@better-i18n/cli`](./packages/cli) | CLI for scanning, syncing, and managing translations | [](https://www.npmjs.com/package/@better-i18n/cli) | | [`@better-i18n/next`](./packages/next) | [Next.js](https://nextjs.org) SDK with middleware and hooks | [](https://www.npmjs.com/package/@better-i18n/next) | | [`@better-i18n/use-intl`](./packages/use-intl) | [React](https://react.dev) hooks for [use-intl](https://www.npmjs.com/package/use-intl) integration | [](https://www.npmjs.com/package/@better-i18n/use-intl) | | [`@better-i18n/expo`](./packages/expo) | [Expo](https://expo.dev) / [React Native](https://reactnative.dev) integration with offline caching | [](https://www.npmjs.com/package/@better-i18n/expo) | | [`@better-i18n/core`](./packages/core) | Core utilities for locale handling and formatting | [](https://www.npmjs.com/package/@better-i18n/core) | | [`@better-i18n/mcp`](./packages/mcp) | [MCP](https://modelcontextprotocol.io/) server for AI agent integration | [](https://www.npmjs.com/package/@better-i18n/mcp) | | [`@better-i18n/schemas`](./packages/schemas) | Shared [Zod](https://zod.dev) validation schemas | [](https://www.npmjs.com/package/@better-i18n/schemas) | ## Quick Start ```bash # Install the CLI npm install -g @better-i18n/cli # Initialize in your project npx @better-i18n/cli init # Scan your codebase for translation keys npx @better-i18n/cli scan # Sync translations with the Better i18n platform npx @better-i18n/cli sync ``` ## Framework Integration ### Next.js ```bash npm install @better-i18n/next ``` ```typescript // middleware.ts import { createI18nMiddleware } from '@better-i18n/next'; export default createI18nMiddleware({ locales: ['en', 'tr', 'de'], defaultLocale: 'en', }); ``` See the [Next.js integration guide](https://docs.better-i18n.com/sdk/next) for routing, server components, and metadata setup. ### React with use-intl ```bash npm install @better-i18n/use-intl ``` ```tsx import { BetterI18nProvider, useTranslations } from '@better-i18n/use-intl'; function App() { return ( ); } function MyComponent() { const t = useTranslations('common'); return {t('welcome')}; } ``` ### Expo / React Native ```bash npm install @better-i18n/expo ``` ```tsx import { BetterI18nExpoProvider, useTranslations } from '@better-i18n/expo'; export default function App() { return ( ); } ``` Supports offline caching, OTA translation updates, and automatic locale detection. See the [Expo guide](https://docs.better-i18n.com/sdk/expo). ### MCP Server (AI Agents) ```bash npm install @better-i18n/mcp ``` Connect AI assistants like [Claude](https://claude.ai), [Cursor](https://cursor.com), or [Windsurf](https://windsurf.com) to your translation workflow through the [Model Context Protocol](https://modelcontextprotocol.io/). ### Agent Skill Give your AI agent permanent better-i18n knowledge — SDK setup, key naming, CDN behavior, GitHub sync, and MCP tool usage — without pasting prompts each session. ```bash npx skills add better-i18n/skills ``` Works with Claude Code, Cursor, Windsurf, and any agent that supports custom instructions.
