Mine is hosted at https://dhruvkb.dev. I also made an open-source project that allows you to build a similar one for yourself. It's called Récivi and it's hosted at https://recivi.dhruvkb.dev.
I prefer the more simple monochromatic approach used by Simple Icons [1] but that can be too restrictive at times and many icons do not translate to that style. You can still use their brand guidelines and license metadata to avoid infringing copyright.
