Apache has mod_md, a built-in LetsEncrypt-compatible module that requires very little configuration and no external daemons or cron jobs: https://httpd.apache.org/docs/2.4/mod/mod_md.html Three lines per virtual host: MDomain, MDContactEmail and MDCertificateAgreement. Using it in production for three years without any issue. I don’t know what’s Apache stance on LLMs, I guess neither for nor against.
