But I don’t wanna lol
Too bad

Nostr.build.
The problem is costs add up very fast: a 100MB file viewed by 1k people becomes 100GB egress, which is $0.1 at best from certain providers. Then there’s CDNs for optimization, and also moderation work to filter out CP and other unwanted content (legal liability). Also, backups.
