Bestie is gender-flexible but still femme-coded; calling a friend bestie reads warm and slightly affectionate. Bro is masc-coded and used between guys or by anyone going for casual masculinity. Both are address terms — neither necessarily means the closest friend.

"Best friend," extended to anyone you're addressing warmly — including strangers on the internet. "Bestie, no" = "friend, that's wrong." Used as both a vocative and a generic Gen-Z address term. The word has become so bleached that it can be sincere or sarcastic in the same breath.
“"Bestie, you can't wear Crocs to a wedding."”
(slang) Brother .
“Bro, you good? You've been lookin' kinda out of it lately.”
Affectionate address — works across genders but reads slightly femme.
Casual address — reads masc, common in male friend groups but used by anyone informally.
