Atuin has been the absolute best CLI tool I’ve found in years.
I use it every single day that I’m at a computer. It's very easy to learn (2 or 3 essential hotkeys), and makes finding old shell commands a breeze. I was able to self-host the sync server in well under an hour, start to finish.
(@ellie - if you see this thread, thanks for all the elbow grease you put in! You’ve built something really special.)
