One company stands behind it.
One repository, one license, one place to read every line that decides a verdict.
Sweep, score, contract, and CI-gate calls, self-hosted on your own infrastructure, with unlimited seats and every capability included. The deterministic checks decide the verdict; the model judge stays advisory unless you opt it in. When the evidence can't support a call, hotato reports NOT SCORABLE rather than guessing.
