https://github.com/mleku/reverse - this is a reverse proxy that i forked and modded to let you host a .well-known/nostr.json file (you have to create it manually). yes, you can directly see these by going to a nip-05 like https://turdsoup.com/.well-known/nostr.json i mean, you can basically copy one that exists, and just put your own npub and "username" (or _ so it shows as mine used to, just the domain, but actually _@mleku.dev, now i just use me@mleku.dev), and you put your hex pubkey in and voila (find it in one of your notes json if you want an easy way to get it). a $5/month VPS with one of these running on it might seem a bit expensive but the reverse proxy lets you put other things there too, like you could host your own media, a little web page, or like me, run a relay on it. though i would understand if you haven't the first clue about operating a unix shell.
