Lots of people have given benefits here so i'll give some of my unique use cases that haven't been mentioned. I use it for reasons mentioned, but also;

- I work at a big org and run 10+ dev services for a mobile app team. My team uses macOS because that is what we are familiar with. We are large enough to not be able to use Docker desktop. The alternatives (Rancher Desktop, Podman) consume between 2 + 8GB before you run your app and they have TERRIBLE file system I/O. Nix gives us isolated, reproducible environments + native i/o.

- Inside our iOS project we are using Nix Shell in the build phases for things like linting, code gen etc. Ensures everyone is on the same version across developers and CI machines. Updating versions is so simple. We can also share a network attached Nix store with all the binaries to save space on CI machines.

- Once you get everyone to install it, you can add new tooling + languages for free by adding nix-env instead of bash as the she bang in your shell scripts. Need to run some ruby thing? Well you know everyone has nix installed, just do nix-shell and add the ruby version you need - its guaranteed to work everywhere.
