If I’m okay with the software (not just trying it out) am I missing out by not using dockers?

No, I think in your use case you’re good. A lot of the key features of containers, such as immutability, reproduceability, scaling, portability, etc. don’t really apply to your use case.

If you reach a point where you find you want a stand-alone linux server, or an auto-reconfiguring reverse proxy to map domains to your services, or something like that - then it starts to have some additional benefit and I’d recommend it.

In fact, using native builds of this software on Windows is probably much more performant.
