Deepseek Dafeiyu Pet is a Windows desktop pet application that monitors DeepSeek API account balance and usage.
The tool solves the problem of tracking DeepSeek API spending by combining a desktop pet character with real-time balance monitoring. It displays account balance, daily usage, peak-valley pricing periods, and per-request consumption statistics. The pet itself is a transparent, frameless window featuring a whale character with three-view animation (front, side, and back) implemented in Python using PySide6. The character can walk freely around the desktop, follow the mouse cursor, or remain stationary, with automatic view switching based on movement direction. Users can drag the pet to reposition it, and it snaps to screen edges for convenient placement.
The application suits Windows users who actively use DeepSeek's API and want persistent visibility into their spending without a separate monitoring tool. It works as a standalone desktop application independent of DeepSeek Harness, making it accessible to anyone with a DeepSeek API key. The tool includes weather display, customizable appearance options, sound effects, and application notifications. Its settings interface organizes configuration across eleven categories including balance and usage, weather, music, appearance, interactions, and performance options. The right-click menu provides quick access to core functions without nested submenus, reducing interaction friction.
Development activity shows consistent maintenance with a structured changelog documenting updates. The project includes comprehensive settings architecture supporting light, dark, and system-following themes. The codebase demonstrates attention to user experience details such as numeric scrolling animations, elastic sound effects, and position-locking features. Configuration files are stored in the user's AppData directory rather than cluttering the desktop, and the application provides straightforward uninstallation through Windows settings.
