Relay tools IS this. It has an api for deployment too. I have many plans to further execute on exactly this kind of thing, inciuding supporting more relay flavors, more self hosting, more networking setups. Obviously, there is an opportunity to revisit and rewrite a lot of it to achieve true 'one click', and I had plans to do this.
BUT I needed funding and I guess nobody on the opensats voting team has seen what I've been doing the last year (for free).. Y'all should give me a boost or something if you think I've helped your projects in the last 2 years+, I feel like I've done a lot, esp for NIP17.
I'm still working on it pretty much daily, and I may apply again with smaller goals I don't really know. The urgency and excitement is suppressed knowing I'm basically on nostr deth row.
The amount of work required to execute on this is quite a lot, and my submission reflected this.
