Stackshare seems the most similar since it is also community based. Those websites seem mostly focused on dev tools.
I want more than just tech stacks and what it is built with. I want the tools to market and monetize, productivity tools, fun tools, etc. And I want it to be like a directory of indie makers and digital creators with a link in bio.
However, if you're planning on monetizing: the competition is fierce. The industry is called Technographics. For example, Wappalyzer can segment millions of companies using thousands of tools (here's their list: https://www.wappalyzer.com/technologies/). You'll see 40 A/B testing tools, 104 Live Chat tools, 63 Issue Trackers. It's intense.
Edit: I just saw Twelve.Tools. Even though you didn't know the websites I mentioned, it's clear you DEFINITELY know technographics! Great site.
I did not know the term Technographics, TwelveTools is just a minimalist directory of tools, but indeed it categorizes tools too.
I think RamenTools won't compete in this industry, it's more taking the way of makers and products than technologies. It may not make millions but it's gonna be a fun project. :)
