Recently started a small project with a limited number of developers and in the end; a limit number of users. But the project has an important function. Decided on PostgREST as backend, with a thin VueJS frontend. We get a backend and API for free, and our developers know SQL very well. I think it's a brilliant choice for our use case, although admittedly not something I would use for some other projects where I'd need more scaling on DB level, etc.
