Claude Code Env (CCE)

English ｜ 简体中文

Are you tired of manually editing environment variables to switch between different models? If you don't want to use claude-code-router, then CCE is a great choice. It's a lightweight command-line tool that allows you to manage and switch between various large models that comply with the Anthropic API specification through simple commands.

Why use CCE?

CCE solves common pain points when using Claude Code:

• ✅ Multiple models - Quickly switch between official APIs, proxy servers, and enterprise networks.
• ✅ Environment variables - Avoid frequently editing environment variables like ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN.
• ✅ Team collaboration - Easily share and sync configurations with your team.

How is it different from claude-code-router?

It should be noted that CCE is not a proxy tool or request router. It's just a client-side environment variable switcher, whose only job is to help you manage and set environment variables (ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN, etc.) for your terminal session. It doesn't intercept or forward any of your requests. This also means that the model service it points to (whether it's the official API, third-party proxy, or other services) must be compatible with the Anthropic API specification.

Install

pnpm add -g @vainjs/claude-code-env
