Make it with your AI

Describe a game to Claude or ChatGPT. Rally gives it a real multiplayer engine, servers and a place for people to play it.

  1. 1

    Connect your AI

    Add Rally Studio to Claude, ChatGPT or any app that supports MCP. It uses the plan you already pay for.
  2. 2

    Describe your game

    Say what you want to make. Your AI builds it in Rally Studio, playtests it with bots and fixes what breaks while you watch.
  3. 3

    Play it with everyone

    Ask your AI to publish it and share the link. Friends play right in the browser with no account, even inside a post on X.
