What is your project about? What are the latency requirements? How many concurrent users you expect to have? If these numbers are not high, why are you not using a general purpose language like go or Kotlin?

I used vapor for a evaluation project a while ago and abandoned it quickly. While Swift is a nice language, it is still a 2nd class citizen on non-Mac systems.

You can do a small PoC project and see if you like it.
