Revvy

A new way to drive Unreal — in natural language.

Revvy is an AI assistant built right into the Unreal editor. With no external tools or API keys, you control Blueprints, materials, UMG, animation, and levels just by talking to a chat panel. Manual work becomes a single sentence. Built by RevStudio and battle-tested daily on real game projects in production.

Highlights

  • It uses the Claude Code CLI already on your machine. No signup, no billing, no token to issue.
  • It handles Blueprints, materials, UMG, Niagara, animation, and landscape — 32 services and 1,068 methods in all.
  • 35 domain skills load only when needed, cutting context usage by 50–65%.
  • Connect from VS Code, Cursor, Claude Code, or AntiGravity over MCP.
  • The MCP server is written in native C++ HTTP, so it runs light with no Python runtime.
  • We use it every day building a real game. It's the tool we use, so it's the tool we fix.
