I recommend most people use Caddy instead of Nginx. The only benefits of Nginx are certain modules providing application-server capabilities, the ability to re-load all configs with zero downtime, and better performance on limited hardware (although most sites won't need to handle more than a few hundred requests per second, which Caddy can handle perfectly well).

+
+[Migadu](https://www.migadu.com)
+: Managed email hosting for seirdy.one. Running my own mail server and keeping my IP approved by all the entrenched players isn't worth the effort, especially if I ever choose to run something like a Tor exit node in the future. Migadu also offers an API, which I use to generate and list email aliases on the fly. My only gripes are that they still support TLS 1.1 and 1.0 for some reason, and that they don't yet support any open IMAP extensions that allow 2FA.
+
+[deSEC](https://desec.io/)
+: Managed DNS name servers. I could run something like PowerDNS or TrustDNS myself, but I'd need to use separate IPs (and ideally a separate server or two) for redundancy. I wanna keep seirdy.one cheap to host, and deSEC was free. It offered DNSSEC along with nice record types like SSHFP, HTTPS/SVCB, and OPENPGPKEY. OPENPGPKEY and SSHFP are especially useful, since keys distribution should have multiple distribution mechanisms with different sources of trust when manual verification isn't ideal.
+
+[Namecheap](https://www.namecheap.com/)
+: Domain registrar. I do not endorse Namecheap. I initially picked it since it ticked the right boxes: Whois privacy, domain locking, DNSSEC, custom name servers, decent support, and good prices. Porkbun and Gandi are other options that tick these boxes.

+[Digital Ocean](https://www.digitalocean.com)
+: My VPS provider. I do not endorse Digital Ocean for most peoples' needs. It's far pricier than equivalent options, and is only worth that price if you need top-tier support and a very good SLA. That being said, it does offer a lot of free credits ($100 if you sign up with someone's referral code; another $100 if you're a student); I started using Digital Ocean for the free credits. Scaleway and BuyVM are much better options if you want to go cheap. If I ever manage to get my hands on a home internet connection with excellent uptime, I might switch to self-hosting.
