TokensTool is a Java-based management interface for PandoraNext, a reverse proxy system for accessing ChatGPT APIs. It allows users to add, refresh, and manage tokens including share_token, pool_token, and access_token. The tool provides a web interface for managing tokens.json and config.json files, supports hot-reload of configurations, integrates with one-api for synchronized token distribution, and includes Docker deployment scripts for one-click setup of both PandoraNext and the token management service.
