Altcoin Alternative Service? Cryptocurrency Similarities?

[PremiumCodeX]

Dear Members, Hi Everyone!

I wonder if a service such as Alternative(dot)me exists, but for altcoins.

Under alternative of a cryptocurrency, I mean another cryptocurrency with the same vision, mission, technical fundamentals...etc.

Do you know about any alternative finding service for altcoins?
Or how else could I find similar cryptocurrencies to the one I like? (Or at least whose campaign is based on the same keywords.)

Thank you very much in advance,
