Nim is “just C” at the end of the day, so by leveraging the —-compileOnly flag you can use Nim anywhere you can use C

Now that arc/orc are the default memory management strategy, it’s even possible to keep some of the niceties from the standard library when doing so — but that will depend on your target of course.

Even going the “no heap allocation” route is totally feasible, you sort of end up using Nim as a nicer C syntax with extra features. All of the libraries we write for work have two interfaces, one that returns (possible heap allocated) results, and one that takes a buffer pointer (as a var openArray[T] param) in instead.
