I'm trying to get a wildcard certificate, but running into the issue that I use Namecheap as a registrar, and for API access I need to spend more money than I'm willing to, so I'm looking for alternative solutions.

One of the supported DNS Servers is LuaDNS, which looks provide what I need. Namecheap supports a 'Personal DNS' option, explained here. Can I register ns1.luadns.net as a personal DNS, and will this, in combination with the luaDNS certbot plugin, solve my wildcard certificate issue?

thanks

Yes, you've pretty much got a handle on it. The terminology is a bit confusing, but you basically need to tell NameCheap that your domain's authoritative nameservers are ns1-4.luadns.net. This would also work the same way with any other DNS provider (there are a ton out there).

NameCheap Custom DNS settings

Then you add your zone over on the LuaDns site, generate your API key and such and you're good to go.

It may take a while for the NS record changes to propagate out over the Internet and you don't want to try and get your cert until they do. You can run dig/nslookup queries against your ISP DNS servers (or a public resolver like Google's 8.8.8.8). But there are also websites that can check a bunch for you like this:
