Yes, the code of the analyzer itself cannot be built on macOS or Windows directly. In those cases you will have to use either podman or docker to use the binaries prebuilt on/for Linux. The whole system depends on a lot of other stuff on Linux so it won't easily run on other OSes.
Ah, that's too bad. For me at least, that makes the barrier to entry too high. Having to learn some new software (docker) just to try some other software is just too much.
