Installation

Install the Babelize CLI and set up your environment in under a minute.

Prerequisites

Node.js 18+

Babelize CLI requires Node.js 18 or later. Check with `node --version`.

GitHub Account

You'll need a GitHub account to connect your repositories.

Install the CLI

Install globally so you can use babelize from anywhere:

npm install -g @babelize/cli

Or run directly without installing:

npx @babelize/cli --help

Make sure everything works:

babelize --version

You should see the installed version number.

Authenticate with your Babelize account:

babelize login

This opens a browser window to complete the login. If you don't have an account yet, create one for free.

Install the SDK

The Babelize SDK lets you translate strings directly in your application at runtime — no CLI, no locale files, no configuration.

npm install @babelize/sdk

pnpm add @babelize/sdk

yarn add @babelize/sdk

bun add @babelize/sdk

For React applications, install the React bindings as well:

npm install @babelize/sdk @babelize/sdk-react

And add the build plugin for automatic lockfile generation:

npm install -D @babelize/vite

See the SDK documentation for a complete guide to setting up translations in your app.

Install the MCP Server

The MCP (Model Context Protocol) server lets AI coding agents like Cursor, Claude Desktop, and opencode interact with Babelize directly from your editor.

npm install -g @babelize/mcp

Or run on-demand without installing:

npx -y @babelize/mcp

Set your API key:

export BABELIZE_API_KEY=bblz_sk_xxxxxxxxx

See the MCP Server guide for configuration with Cursor, Claude, and other AI tools.
