OpusBar: a pixel cat in the macOS menu bar that shows which Codex session needs you

[kushalBanda]

I built this. When several Codex sessions run at once, one can sit on an approval prompt in a window you are not looking at. OpusBar puts a pixel cat in the macOS menu bar. It takes the state of the most urgent session: running, thinking, needs you, done, error or idle. A badge counts the sessions waiting.

For Codex:

• Sessions in any terminal, tmux pane or editor show up within 30 seconds, before you connect anything.
• Connect Codex in Settings > Agents and the cat also knows what each session is doing. Run /hooks in Codex once and approve OpusBar's hooks.
• 5-hour and weekly limits with reset times, per CODEX_HOME. Warnings at 80% and 95%.
• Usage over 24 hours to 90 days by model and project, with an "API value" at OpenAI list prices.
• Local only. No account, no telemetry. The hook drops your prompts, code and replies before OpusBar sees the event.

It handles Claude Code the same way. Free, open source (Apache-2.0), macOS 14 or later.

What would you want a menu bar to show about a Codex session that it does not show today?
