I believe this kind of service is the way forward when it comes to developer tooling. But paying $39/mo/user for having the right to deal with the deployment myself for a tool that is still alpha is pretty high. I understand the (tremendous) value prop, but that's the kind of price I'd be expecting from a SaaS version, not from a self-hosted app. Although not giving a discount for self-hosting and a price per user is the "modern" way to do open source (see gitlab or mattermost), it still feels a bit wrong.
Anyway, excuse my old man rant, awesome work and good luck making a business out of it! I'll give it a try.
For me it's a different issue. To me, Developer Tools are very personal, and I've come to view using non-free IDEs as a waste of time in the long-run. If I'm going to set it up for myself individually, I want the whole thing to be open source*.

It was this philosophy that kept me away from JetBrains IDE's for years. Eventually, someone talked me into giving it a try and there was no going back for me! Basically ALL the other software I run, from the OS on up, is FLOSS, but I happily pay to run WebStorm for my JS/TS development! The value provided to me is light-years ahead of the Eclipse/VSCode flavor of the month.
I remain a firm proponent of FLOSS, but I am also realistic about the value of truly great proprietary software!
