Balance Panel — DSH's Scalable Balance/Usage Panel

Balance Panel is a floating balance panel plugin for DeepSeek Harness, designed to address the cumbersome hassle of checking balances when switching between multiple backends. It is fixed on the right side of the Web UI and automatically switches its displayed content based on the current session, supporting three backends: OpenCode Go (subscription quota), Zhipu, and DeepSeek (pay-as-you-go billing). The plugin adopts an extensible architecture and supports adding new providers through configuration. After installation, it must be enabled in Settings, and a refresh interval must be configured. The plugin is secure and reliable: API keys are parsed only on the server side, and it includes independent caching and cross-site protection mechanisms.
