Barista

Barista is a menu bar switch for macOS's built-in caffeinate command. Turn it on to keep the system or the display awake, and turn it off to let the Mac sleep again. You choose which caffeinate options apply, and it can switch on automatically when it starts. It suits people who want caffeinate without a terminal, although it does not expose every caffeinate option.

It requires macOS 13.6 or later and is a universal build. The DMG is not notarized and carries only an ad-hoc signature, so macOS blocks the first launch and you need to allow it in System Settings.
