How do I see every package installed on Ubuntu?

Moving to a new machine and I want a list of what I installed so I can put the same stuff back. Is there a command that shows only what I added myself and not the whole system?

apt list --installed gives you everything, but it's thousands of lines, so pipe it: apt list --installed | grep firefox, or | less to scroll. if you only want the stuff you actually chose to install rather than every library pulled in with it, apt-mark showmanual is much more useful. and snaps don't show up in either of those, run snap list for them (flatpak list too if you use flatpak).
