Qovery Engine – open-source multi-cloud deployment

Overall it seems badly designed, so one of the 3 cloud you picked-up did not work for whatever reason, what is the state of your deployment, 2/3? Can you reconcil? It looks like fire and forget, not very applicable in a real scenario.
Heroku still has one of the easiest setups of anyone on the market, and they've just been coasting in recent years. Poor container support, auto-scaling is naive, random routing (see rap genius), no health checks, pricey, etc.
Previously Deis built a Heroku like service on top of Kubernetes, but they got acquired by Microsoft, and the product has since atrophied.
Convox[0] seems similar to Qovery, with the added ability of self-hosting (UI is closed source though).
I think Qovery not having a UI is a deal breaking for many. Heroku's CLI, UI, and API is a killer combo.
