I'm working on a Heroku / Render / Flyio alternative thats free, open source, built on top of Kubernetes.

Supports deployments of your own apps as well as 15k+ other packages (postgres, airbyte, dagster, etc) via helm charts.

Reason? Got sick of paying for the massive markups on PaaS but missed the simplicity and convenience.
