Zerohedge is a good news site that caters to right/libertarian.
Revolver.news is a news aggregator that leans right/libertarian. It's basically like Drudge before Drudge went left after Trump.
Besides resources like this one and the super small list above, I'm really not sure anymore.
I can no longer recommend Reason. They used to be half-decent but they're fully co-opted by the left now.
The Cato Institute was decent-ish once upon a time, but I believe they were also co-opted by the Kochs (neocon/RINO).
And you'll never see me recommend Reddit. It's a leftist AND bot hellscape now. BUT, check out the anarcho capitalism sub if you're over there. It's probably the last bastion of true ancap/libertarian discussion.
I'd have to guess you can still find at least a handful of decent libertarian personalities on Twitter/X that have their own blogs or something.
