Down the track I believe we can deliver a self-hosted solution.
Also in the next couple of weeks, with just a user id, you will be able to place a call directly from Zendesk (for example) without us knowing anything about the user.
Has varius API integrations too
It is a nice project, but the docs need some love. You can also hire premium support for 30usd/month directly from the creator of the project, which I'm sure would happily help you with your prod deployment!
You have also development docs on docker / ubuntu / mac / win!

I would certainly try/ dig deeper / pay 30usd, it's the best alternative I've found so far!
