I often use pkgstats to check the popularity of Arch packages I use. Sometimes I notice a package is declining in popularity, and I’d like to find similar alternatives that are trending instead. Something like https://pkgstats.archlinux.de/fun
Are there any sites that categorize Linux software and show popularity within each category, so it’s easier to discover alternatives?
I don’t know of a service that tracks all major repositories to calculate a single popularity index. They are not really comparable to each other anyway.
Depending on what type of application you search for, I think “Flathub” could be one major source. It’s a pretty popular “platform” and not dependent on a certain distribution. There are “Trending” and “Popular” categories too. It’s excellent to find some new software (or to remind an older one exist) in my opinion. You don’t even need to install the Flatpak and can do it from Archlinux repositories (or the AUR if you prefer).
