I haven't had any issues with `fnm` so far. It's been fast and I like how it prompts you to install a missing node version as soon as you jump into a directory with a `.nvmrc` file.

All the package managers that provide shell wrappers kinda tend to be bad at this, unless they use their own command to wrap over project specifications, like uv.

These days, I've been personally relying more on direnv to automatically activate certain shell configurations, and then nix to manage binary dependencies like node or go or php.
