StableBar

StableBar replaces or sits below the macOS menu bar. Built-in widgets show workspaces from AeroSpace, yabai, OmniWM or macOS Spaces, the frontmost app's menus, the clock, CPU and memory, network, battery, sound and your next meeting, without running any scripts. Any widget can open a popup with graphs, lists, sliders and toggles, and any script that prints text or JSON can be a widget.

You set it up in the app: a guided setup picks a preset, a theme and a placement, and shows each choice on your real bar. After that, Settings saves to a plain JSON file you can also edit by hand. StableBar is notch-aware, puts a bar on each display and can keep windows clear of it. More themes and widgets come from a built-in store.
