Two shortcomings that we are aware of and working on: - Persistent storage - Custom domains
Once we get those, we think the service will be incredibly valuable to people wanting to learn Kube or needing to deploy a web app without having to jump through the hoops of setting up a cluster on one of the big cloud providers.
We are aiming for absolute simplicity for beginners who otherwise wouldn't have tried Kubernetes; for example, people who are currently running a few personal projects on a single $5 droplet. Our app gets you set up with one click via github auth, and you should be able to deploy your personal projects on Kube for free now.
