Be more specific, how exactly does it benefit a developer?

The English doesn't quite make sense in the sub title. Change "There are thousands of ways to write an app. codelib.code helps you find how world use tools and give you the inspiration for building better software." to "There are thousands of ways to write an app. codelib.code helps you find how the world uses tools and gives you the inspiration for building better software."

So the app is to see how other apps use certain javascript libraries? I think the "Knowledge at your fingertips" would be better being more specific, a concise sentence saying how your app helps a developer.

Thank you so much for your feedback, it's right on point about what my landing page was missing. I'm changing a lot of the content now :)

I feel like setting the amount of days you want to get stuff done on in advance and then using the streaks as a way to stick to that. So like you say you want to get things down 5/7 days and then your streak continues unless you miss three days in one week. I tried to keep up a streak initially, but with a baby there were days when it simply was not possible to even get near my laptop.

For some context: I clicked through to the site with no knowledge of what your app did. For me I couldn't quite determine the purpose well enough with the main CTA text "Intuitive tool to find the most efficient texts on your site" I guess what it is missing to me is what is the goal, as the text would only be efficient depending on the goal. I feel like it needs more emphasis on what pain point it is trying to solve for your target audience.

I think search could belong in the header. Perhaps in the center. I don't think people will discover it in the more menu. Would be cool if you extended it in future to be work like the wip menu bar app as well, so if you are logged in you could create/complete todos from it.

Good idea on finding others who have implemented something before

An awesome milestone congrats!
