Note that Cloudflare doesn't proxy wildcard domains unless you're on their enterprise plan.

Which means you also cannot use Argo Tunnel / Cloudflare Tunnel if you need wildcard domains unless you're on an enterprise plan.

Most sites probably don't need it, but I was surprised by it. Especially having it only be available in the "Ask for Quote" pricing tier makes Argo Tunnel a bad solution for many projects.

In the examples they provide at the bottom of the article - my instant reaction is - these tunnels can replace ngrok tunnels.
