This entry (heroicons.dev) is a third-party web viewer, built by developer zaydek and not Tailwind Labs, for browsing and copying the official Heroicons icon set: the same 300+ MIT-licensed icons found at heroicons.com.
It offers an alternate browsing UI (dark mode, flexible search) for the same underlying icon data, which some users find faster or preferable to the official site.
Good if you specifically prefer this viewer's UX; functionally redundant with heroicons.com since it mirrors the same icon set rather than adding unique icons.
Not the official Heroicons site: the canonical source and any licensing questions should go through heroicons.com and Tailwind Labs, since this is an independently maintained mirror.
Open-source icons from the team behind Tailwind CSS.
