dsh-price-phase

DeepSeek splits the week into peak and off-peak rate tiers, and the off-peak price is exactly half of the peak one, yet most GUIs never tell you which tier you are in at any given moment. dsh-price-phase adds a tiny badge to the DSH Web GUI input toolbar that shows whether you are currently in peak or off-peak hours, along with a live countdown to the next state change. It recalculates every thirty seconds from the system clock, and a hover reveals the current Beijing time, the surrounding time bands, and exactly when the switch will happen, all without opening a popup or navigating elsewhere.

The plugin deliberately does one thing and one thing only: no multi-timezone conversion, no rate comparison tables, no click interactions, and zero network requests. Every calculation derives from the browser local clock converted to UTC+8, so it works offline, carries no latency, and never shows a wrong state because an API call failed. Weekend countdowns are precise as well; after Friday 18:00 the next switch points to Monday 09:00, not Saturday 09:00. There are no third-party dependencies; the only require call is for react.

It is built for users who already access DeepSeek through the DSH Web GUI and want a glanceable cost-rate indicator before hitting send, especially those who factor running costs into daily habits. Users outside China can use it directly as well, because the plugin judges hours by Beijing time, which is the official reference; converting to a local timezone would actually produce the wrong result. If all you need is a quiet, accurate, bandwidth-free phase badge rather than a full dashboard, this plugin was written for exactly that.
