Reddy

AI IDE for game development

Make games with Reddy

Write code, build, and ask your editor to get things done. Reddy brings the work of making games into one IDE.

01 / PROJECT

Open your project and get started

Add your game project folder. Reddy identifies the engine and prepares the editor connection, with code and assets together in one workspace.

Project setup details

  • Connect the right engine

    Project files identify Unreal, Unity, Godot, or Roblox.

  • Prepare the editor connection

    Reddy installs the bridge for the first connection and guides you through updates or plugin activation.

  • Connect your AI tools

    Connections are configured so your AI can inspect or edit the game editor.

  • Check your changes

    Updates check for files you edited. If changes are found, Reddy identifies them and stops the installation.

Keep project decisions and conventions in a shared note for later conversations to reference.

02 / BUILD & DEBUG

Make a change, then build

Choose a run configuration to build or debug your project. Select an error to jump to the code that needs attention.

The run bar: a Build and run editor dropdown, a run button, and a connection indicator.
Choose a configuration and press run.

03 / REVVY

Ask your editor to get things done

The Revvy mascot — a white robot rabbit with mint and lavender ears.

“Show me the actors in this level.” Use the Revvy tab to inspect the running editor or make changes.

Your current AI and editing permissions are shown in the toolbar.
  • Connect Claude or Codex
  • Safe to inspect, Full to edit
  • Choose models from your installed CLI
  • Continue a conversation or start a new one

Changing AI or permissions starts a new conversation. In Claude, use /resume to return to an earlier one.

A closer look

Code and projects, together

Keep your code editor, terminal, Git, and browser in one window, with navigation and code tools built around game projects.

  • A project view for games

    Temporary build folders are hidden so you can focus on code and assets.

  • Find your way through code

    Use completion, go to definition, find references, and rename. Unreal code indexing starts when you open a C++ file.

  • See related Blueprints

    With the editor open, UCLASS declarations show how many Blueprints inherit from the class.

  • Work on tasks side by side

    Use separate worktrees, run multiple AI tasks, and schedule automated work.

  • Build targets are read from your project’s settings.

  • Compiler errors and Korean Windows console output are supported.

  • Engine-specific debuggers let you inspect execution with breakpoints.

FAQ

Which AI can I use?

Connect an installed and signed-in copy of Claude Code or Codex. You don’t need to enter a separate API key in Reddy.

How is project data handled?

Reddy connects to the editor on your PC. Data included in AI requests is handled according to your CLI and AI service settings and policies.

Does the editor need to be open?

It needs to be open for inspection and editing. Code navigation and builds also work with the editor closed.

What can I build?

Builds currently support editor targets on Windows. Game cooking, packaging, and Roblox run configurations are not included.

Which engine versions are supported?

Unreal targets 5.8 and Unity targets 6000.3. Godot uses the 4.5 API and has been checked on 4.6.1.

How does AI billing work?

Usage follows the account and plan of the AI service you connect. Check that service’s terms for details.
