Oh gotcha - the 'pricing' page initially gave me the impression that routing was closed/paid. But I guess it's just hosted deployment?

Yes, exactly.

Our commercial offering provides more insight into your iroh deployment as well as a hosted relay network. At the enterprise tier you can also get priority access to our engineering team.

Obviously we want to make people aware of these services. But we also have projects that use iroh at large scale without using iroh services.
