I skimmed through their docs but couldn't find whether they:

* support for abstract apps, not only HTTP/web apps like heroku, let's say I want to deploy a SIP app

* support for HTTP/2 and potentially HTTP/3

If they do support these two I would say it's enough to be considered Heroku killer.

You can route arbitrary TCP or UDP services through our load balancing layer just fine. I'm not sure what SIP actually needs, but it might work. We don't currently have a way to route TCP connections directly to individual VMs, so stuff like WebRTC doesn't work.

We do support HTTP/2.
