akregator is unfortunately part of the kde-pim, requiring akonadi, and a bunch of kde deps, see for example:
% pacman -S akregator

I was hoping there’s something which way less dependencies, hopefully GTK rather than Qt… At some point I wanted to use kmail and korganizer, also part of kde-pim, but besides korganizer never fixing a pretty old bug, the amount of deps I needed, plus the akonadi DB, made go back on that attempt. The same goes for akregator unfortunately…
