Recently it’s come to my attention that Caddy has an AI sponsor so I have been looking at moving away from Caddy.

I’m currently looking for another reverse proxy to use in place of Caddy. For TLS I am looking into using CertBot and it appears there’s a module (https://github.com/desec-io/certbot-dns-desec) I can use that works for https://desec.io/ to handle my certs.

I have two questions, the first is about CertBot. Since Caddy is handling my certs automatically, how often would I want to renew my certs? Desec.io has this command to obtain a cert:

certbot certonly \
     --authenticator dns-desec \
     --dns-desec-credentials /etc/letsencrypt/secrets/$DOMAIN.ini \
     -d "$DOMAIN" \
     -d "*.$DOMAIN"

Would I be required to run the same command periodically to renew my cert?

My second question is a bit more open ended. I am looking to hear any suggestions or experiences about different reverse proxies that are preferably free of AI. There is a list here with some suggested alternatives: https://codeberg.org/ethical-foss/open-slopware#web-servers
