Both are Mac menu bar apps. Usagebar does one job for Claude Code: how much of your 5-hour and weekly limit is used, and when the next window opens. Cost Doctor shows those limits for Claude Code and Codex, then names the session that used them, says why, and tells you when something has failed.

Cost Doctor is a Mac menu bar app that reads the logs Claude Code and Codex already write. It names the session that is using your tokens, says why, and turns your screen red when a check fails while an agent sits waiting. Nothing leaves your Mac.
