Not in the near future. We've realized that the "staging" workflow is quite different than production, and companies like Render, Heroku, etc.. are missing a few key features that we wished were there; so we're doubling down on per-PR staging.
Yea I had the same question. I'm interested in this but it doesn't make sense for me without the production piece or having it run on top of our own Kubernetes cluster.
We do offer an on-prem solution if you're interested. You could simply spin up a kubernetes cluster on your infra and "helm apply". Feel free to reach out at my email above if you want more specifics.
