I get annoyed that no one mentions software for just the user. Part of the joy of programming is making stuff you want not just to sell or to get famous. I vibe coded so many chrome extensions I lost count. Most apply just to one site, they save me one click or something. It's fun!
Wouldn't it be easier and/or faster to create a userscript? I've "vibe coded" tens myself, but never really saw the use case for making a full extension out of any of them. Genuinly curious what you made.
