It's hard for me to say. I've written a few random open source projects for Wordpress and Webpack that consistently get a few hundred daily downloads even 7 years later, but it's all behind the scenes stuff that doesn't really get talked about even by the people that use my projects.
I've also created a question-based card game for social connection that I produced and sold 200 units of. Far less scale, but people tell me weekly about the impact that it had on their lives and the connections that they formed through it. It's really shaped the values of the social community I belong to, so in a ripple effect kind of way, I think it's had a pretty huge impact.
And I've also worked on some
widely used web apps for NASA and OpenStreetMap, written a lot of code and shipped some big features but only as a productive IC.
