There's quite a few different variants of kimchi, including non-spicy ones, known as white kimchi (백김치): https://en.wikipedia.org/wiki/Baek-kimchi

There's also diced radish kimchis (깍두기), sometimes non-spicy as well.

It's also the OG kimchi as Koreans didn't have red peppers until the Columbian Exchange (but have been preserving vegetable via brines since the Three Kingdoms era)!
