The documentation regarding Argo and Argo tunnels is a bit confusing for me and every single blog post and/or third-party article always mentions that “Argo” is a paid service. That’s exactly what I see here.
However, I have created a couple of Argo Tunnels and everything is working. I have not enabled “Argo” or "Argo Smart Routing) and I don’t intend to (for the foreseeable future). In this scenario what are the limitations of this “free” service? How free is free regarding Argo Tunnels? Are there any speed constraints or bandwidth limits when using Argo tunnels WITHOUT Argo Smart Routing? Is it really free?
