Hi @rebootcode,

There’s no limit on how many subdomains Caddy can manage. You can point as many as you like as long as you’ve configured Caddy to handle them.

You’ll want to know about LetsEncrypt’s rate limits, though:

The main limit is Certificates per Registered Domain, (50 per week). A registered domain is, generally speaking, the part of the domain you purchased from your domain name registrar. For instance, in the name www.example.com, the registered domain is example.com. In new.blog.example.co.uk, the registered domain is example.co.uk. We use the Public Suffix List to calculate the registered domain.
