This looks beautiful. Are the alternatives simply listed in order by their GitHub stars? How do you handle projects hosted on Gitlab, Bitbucket, etc. Surely it wouldn't be fair to do a 1-1 comparison, right?

Have you looked at alternatives to your site like AlternativeTo and LibHunt? Do you plan on using any of that data as well or perhaps even linking to pages on those relevant sites? Sorry for the unsolicited advice, but I feel like being able to take advantage of the work already done by those platforms in some way could be a big step towards setting you apart. Just saying as someone who uses/contributes to AlternativeTo a lot
