In Caddy 2.3, Caddy [1] will default to both Let's Encrypt and ZeroSSL [2]. If it can't get a cert from one, it will try the other. You can configure more too, including self-signed certs, as a last fallback for example. Caddy will be the first web server and ACME client to support multi-issuer fallback. (Pre-releases coming soon, or you can build from source and try it today.)
ZeroSSL's website is being updated to clarify that certs are free and unlimited through ACME. You can even view them in your ZeroSSL dashboard.
