Those of us that use Nix don't have the problems you complain about. Just write (or vibe-code) a flake.nix for each project, and you can have arbitrary versions of whatever language (Node, PHP, whatever), arbitrary environment variables, port setups, and whatever else. Add in Direnv and you don't have to do anything but `cd` into your project directory. Then simply add an extra output to create a Docker image for your project.
The idea of paying double digits annually for a service that's basically a weaker version of Nix, and which lacks Linux support, is absurd.
