This allows deployments to skip local Nix evaluation entirely using a single `fh` command, making it viable even on memory-constrained devices. The post walks through a Home Manager example supporting macOS and Ubuntu, explains the CI/GitHub Actions setup, and notes that Magic Nix Cache's free tier reaches end-of-life on February 1st, 2025. The same approach extends to NixOS, nix-darwin, and custom packages. ## Full article daily.dev links to this article rather than hosting it.
