"Speaking as a dev with over 12 years of experience in both dev and ops"

I think you aren't the target market. The target market is probably people who are new to coding or even self-taught indie hackers who aren't too technical but oriented towards building a product as quickly as possible

OK I have been the ultimate decision-maker in a number of SaaS vendor selection situations so I am the target market for people who would build an offering using this. I can tell you that multi-tenant shared anything is pretty much an absolute dealbreaker for me and most people like me. Why?

1) In any financial regulated environment your regulator will usually specifically require this (at least in jurisdictions I'm familiar with). Am I prepared to go to battle with my regulator on behalf of a vendor? Most definitely not.

2) Even if I'm not in that situation, do I trust the vendor to have tech protections that work well enough that my customer data won't leak if there's some sort of problem, leading to a GDPR/data protection nightmare? No. No I don't trust anyone that much. I wouldn't even trust code that I myself had written that much (ie when I have built b2b saas solutions I have insisted on single tenant shared nothing). I've actually used (a demo of) a multi-tenant saas where the vendor has insisted on the security of their multitenant solution and been shown another customer's data on more than one occasion.

3) Even if I did trust the vendor and wasn't in a regulated environment which required single tenant, would I be prepared to go to war with my internal legal counsel over the data protection implications of multitenant? No. I want to keep a good working relationship with them and their life is hard enough as it is. They want single tenant shared nothing that's good enough for me.

4) Even if none of the above applies a lot of big corporates will want the option to host a solution in a cloud subaccount that they own. That's clearly not on the cards with something like this.

As someone whose background is primarily in embedded systems, how common are single tenant SaaS architectures?

The only webapps that I've released commercially were all intended for internal use by a single customer, running on their private hardware, with usually only a single login, so I'm about as far from this space as you can get and still be a dev...

I was always under the impression that most SaaS was multitenant, with the individual tenants sharing tables, but being disambiguated by customer ID. Am I that far off?

Is there a list anywhere of these types of checks you do which are critical to approving a saas vendor?
