zpoweralertd gives you power notifications as you need them. Paul Allen has mistaken it for poweralertd, which seems logical, because zpoweralertd also depends on UPower and a notification daemon such as mako, and in fact does the same exact thing poweralertd does, and it also has a penchant for D-Bus integration and lightweight code. poweralertd and zpoweralertd even support the same command-line arguments, although zpoweralertd is slightly more modern.

If you couldn't tell by now, zpoweralertd is a Zig rewrite and drop-in replacement of poweralertd.
