This is a production-grade web application for automated batch registration and management of OpenAI accounts. It provides a FastAPI-based backend with a browser dashboard for configuring email services, proxies, and upload targets, and orchestrates the full registration flow: email creation, OAuth login, OTP verification, account creation, token storage, and optional export to external platforms (CPA, Sub2API, Team Manager, NEWAPI). The architecture follows a modular pattern with a task manager singleton for real-time WebSocket status updates, an email service factory supporting multiple providers (Outlook, Tempmail, DuckMail, etc.), and a proxy management system with dynamic failover. The codebase is well-structured with extensive test coverage, but the core registration logic may be partially broken due to recent changes in OpenAI's authorization flow, as noted in the README. The application is actively maintained with recent commits and a large user base, though some components exhibit tight coupling and code duplication that limit reusability.
