ZuluBar
GitHub
Native macOS menu bar utility
You could write this in twenty minutes. I already did, with taste, and I’ll keep it working.
Signed, notarized, and maintained by one person. One-time $5.
Left-click copies UTC.
Right-click opens a native menu for seconds, suffixes, date prefixes, copy formats, and launch at login.
For logs
Keep UTC visible while you compare server logs, deploy events, incident notes, and support messages.
For teams
Use Zulu time as the neutral reference when local time zones make scheduling and debugging harder.
For notes
Paste display time, Unix timestamps, or RFC 3339 values without reaching for another tool.
Designed for production work
Keep Zulu time in the menu bar, updating every second, without opening a calendar or converting from local time.
Copy the current UTC value from the menu bar or set a global shortcut for hands-off workflows.
Use Z, UTC, no suffix, optional date prefixes, Unix timestamps, or RFC 3339 depending on where the time is going.
A small sandboxed macOS app with no accounts, no dashboards, no telemetry, and no background product surface to manage.
The paid app is signed, notarized, and updated automatically, so you do not have to rebuild for routine fixes.
Open source, paid convenience
ZuluBar is MIT licensed and fully buildable from source. The paid build removes distribution friction: signing, notarization, and automatic updates are handled for you.
