The control plane for AI-assisted development: describe a product in a sentence, see the plan before a byte is written, and build behind gates that actually block — reuse enforced, security forced, every number on this page generated from the sources it claims.
No signup for the intake — it runs in your browser and produces a file you own.
One sentence. The intake reads what it can, quotes its evidence, and asks only what's left — six irreversible decisions always wait for you.
Nothing is written until you've seen every file, every skip, and every reason. "Where did the marketplace go?" is answerable from the plan itself.
13 stages, 3 human gates. Row-level security forced, migrations additive, prototypes structurally unable to ship.

Step 0 happens in the Console: answer the intake and press Download rathvan.json — that file is your answers, and the command above turns it into the repository. The plan prints first and writes nothing.
