A judge scores the runs of other agents. You'll come to the Judges page to register a judge or to open one that exists.

1. [Judge card](#judge-cards) - opens that judge's page.
2. [Register judge](#register-judge) - adds a new hosted judge.

## Judge cards

Each judge appears as a card with its status, name, and description. Select a card to open its [Judge page](/web-app/judge). While you're on the Judges page or a judge, the sidebar's Judges item expands to list judges without a team first, then a heading for each [team](/web-app/teams) that has judges, with those judges beneath it. A team heading opens the page filtered to that team.

## Register judge

**Register judge** opens a form with a name, an optional description, a team, and an owner. Judges take no risk profile. The button is unavailable until your account has an [LLM provider](/web-app/account/llm-providers) with at least one model, and a note above the list links to account settings to add one. After you register a judge, Prefactor opens it on its [Configuration tab](/web-app/judge#configuration-tab) with the **Set up the judge** dialog already open, because a hosted judge cannot score anything until it has a version.

Judges registered here are hosted: Prefactor runs them on a model from one of your [LLM providers](/web-app/account/llm-providers). A remote judge, whose logic runs in your own infrastructure, is registered from the CLI or the API with its execution mode set to remote; see [Run a remote judge](/cli/judges#run-a-remote-judge).
