Ugh. Do you really want that though? They do have a store don't they? Just no one wants to use it.
Debian has had a browseable catalog since forever but it's still waaay better to just go to a third party's website and see how they say to install whatever thing.
Yeah, but that's just because Debian's software catalog is deliberately full of outdated and/or broken packages. It's like that on purpose. On most other distros native packages trump third-party install scripts any day of the week. On Debian you can just use Nix or Flatpak to get good packages.
