I'm sorry we haven't delivered a better self-hosting experience. This is clearly something we could do better. As I mentioned in your link[1], we're targeting a release of our CLI in Q1 (last week of march).
> its a been long time since their launch
It has been 8 months since our alpha launch*, and just over 1 month since our beta. I hope that sets some context, because personally I think we (and the community) have delivered a lot in that time. I'm very proud of what our small team has been able deliver.
> The product is not self hostable
Note that Supabase is self-hostable, it's just lacking documentation, which we will rectify in Q1.
