Overview

Zapy is an AI-powered CLI tool for Unity game development: point it at a game design document and it generates the corresponding Unity C# scripts.

It lives in a production-grade TypeScript monorepo, with Python in the AI pipeline — built to shorten the distance between a designer’s intent and running gameplay code.

Highlights

01

Design-doc to code

Transforms game design documents into structured Unity C# scripts using LLMs.

02

Production-grade monorepo

A disciplined TypeScript monorepo setup with shared tooling across the CLI and AI pipeline.
