Back in the day (2017), when I was just getting started with react and graphql, I was looking for a little (useful) side project I came up with the ecosystem explorer.
Here's the original description from my Hackernews submission: Based on the github api and github topics, look up and compare popular repos for any framework or technology.
Original motivation: As a react developer I find it quite inspiring to look from time to time what is going on the angular or vue world.
As an example, go ahead and compare react, vue and svelte.
The tool never got any attention really, but I still use it from time to time, and usually I do come accross something interesting.
