Codex Reset Radar is a web dashboard that helps developers track Codex usage limits and uncertain reset windows. It shows the current usage-limit and reset status, keeps 26 weeks of reset history so past patterns stay visible, and surfaces public reset announcements from Tibo beside the measured data. Predictions are presented as evidence-based likelihoods rather than exact countdowns, and stale or missing signals are called out instead of being smoothed over, so a developer can decide whether to continue a heavy AI coding session, pause, or move to work that does not depend on the next reset window. It runs in the browser, is free to read, and requires no installation or account.
