Updated my apps to describe what I use them for. But it’s funny you mention this because as I switched away from cloudflare tunnels I was learning how to get all of it working with nginx proxy manager. Took me a while cause im a dns/ssl noob. But I learned a lot and then switched to caddy for its simplicity.
Now a local caching dns server is not something I’ve thought about before and while not something I’d probably need it would be a great learning experience.
I did learn a bit about lets encrypt but happy caddy handles it all for me now. I still need to learn more though because I need to do some tls verification skipping for some of my sites. The other ideas are cool too. Thanks !
