Universal OAuth authentication library for AI providers’ MAX subscriptions. Currently supports Claude AI with Gemini, Grok, and ChatGPT Max coming soon.

​
Features

  • MAX Subscription Access: Leverage your existing AI provider MAX subscriptions programmatically
  • Multiple Providers: Claude AI (available), Gemini, Grok, ChatGPT Max (coming soon)
  • Environment-Specific Builds: Separate Node.js and browser-compatible builds
  • OAuth 2.0 + PKCE: Secure authentication with industry standards
  • Token Management: Automatic token refresh and secure storage
  • Browser & Node.js: Works in both web applications and server environments

​
Why Use MAX Subscriptions?

Instead of paying per API call, leverage the subscriptions you already have:
  • Cost Effective: Use your existing MAX subscriptions instead of pay-per-use APIs
  • Higher Limits: MAX subscriptions often have higher rate limits and priority access
  • Latest Models: Access to the newest and most capable models in each provider’s lineup
  • Consistent Experience: Same interface across different AI providers

​
Installation

npm install @vibe-kit/auth

​
Environment Compatibility

  • Node.js: Use @vibe-kit/auth/node for full functionality including file system access and browser launching
  • Browser: Use @vibe-kit/auth/browser or default import for browser-safe functionality
  • Universal: The default import provides browser-safe functionality that works everywhere

​
Security

  • Tokens are stored with restricted file permissions (CLI)
  • Automatic token refresh prevents expired token usage
  • PKCE (Proof Key for Code Exchange) for secure OAuth flows
  • State parameter validation prevents CSRF attacks
