Codex Reset Radar
Web
Codex Reset Radar
Codex Reset Radar is a web dashboard for developers who use Codex every day. It shows how much of the current usage allowance is left, when the next reset window begins, and whether the window is a direct reset or a banked rollover. It records a dated reset history for every past window with start time, end time, consumption and reset type, and it collects public Codex reset announcements so an unusual reading can be matched with an official note. Everything runs in the browser with nothing to install, and the main use is scheduling heavy refactors and batch runs against real reset windows instead of guessing.
