20+ years ago, Lindows had a great app store that let you create an “aisle” of your favorite apps so if/when you’d reinstall your OS, instead of searching and installing all your apps one-by-one, you’d just go to your aisle, click “install all” and boom.
Is there anything that exists like that today?
Assuming you are using an apt/dpkg distro:
Save the list of packages on your reference system:
dpkg --get-selections > packages.lst
Then install packages based on that list on your target system, after updating the list of available packages:
dpkg --merge-avail <(apt-cache dumpavail) dpkg --clear-selections dpkg --set-selections < packages.lst apt-get dselect-upgrade
