Interesting ... just tried it on Brave Search, and they work there as well.
Once you start using DuckDuckGo with "bangs," it's hard to go back. Just add "!" followed by a platform's initials to your query for a site-specific search.
'!chat' for AI, '!r' for reddit, and '!yt', & 13,567+ 🤍🤌
If you're still using Google, give DDG a serious try. When you really need Google results, just add "!g" to your query. It's simple yet powerful.
DDG isn't perfect, but Google is worse—it's not even close.

Brave is my go-to; I use it all the time with !brave on DuckDuckGo.
I avoid !g and DuckDuckGo's default search as much as possible. Since DuckDuckGo uses Bing, the results aren't great.
Interestingly, Brave is building their own independent search index, which is really great and important.
I mainly use DDG to search other sites.
