What is Tomato for NixOS?

Tomato's a visual DAG editor that builds NixOS configs as graphs, generates configuration.nix, and deploys with one click.

How does Tomato handle NixOS deployments?

It uses nixos-rebuild switch on your real machine, pulling ambient settings from OODN registry for smoothly deploys.

Will Tomato replace manual Nix editing?

Not fully yet—it's early—but for stacks and modules, its drag-drop beats text files, especially with pre-builts like Grafana.
