Nixᛦ is used for both developent and deployment; the production version in particular is deployed to a DigitalOcean droplet running NixOSᛦ. Nix makes reproducible development environments easy and possible. A testament to this is how easy it is to contribute to neuron (see CONTRIBUTING.md) - as with one command, nix-shell, you get the full development enviornment including Haskell IDE support starting from a pristine system with nothing but Nix installed.
