The Core Mission

Never get blocked in the middle of a refactor.

Hitting an unexpected 5-hour rate limit kills developer momentum. LimitBar sits quietly in your macOS menu bar, giving you instant situational awareness of your quota, costs, and provider health.

⏱ Precision Reset Countdowns

Plan deep work around actual reset windows

Stop guessing whether your prompt will trigger a lockout. LimitBar calculates per-provider session, daily, and weekly resets down to the minute, showing exactly how many tokens and minutes remain before refreshing.
