Roblox Game Architecture Reference

1. Overview

Load this reference when:

• Starting a new Roblox game from scratch and need to decide where code and assets go
• Organizing or refactoring an existing codebase that has grown unwieldy
• Answering architecture questions: "Where should this script go?", "How should client talk to server?", "How do I structure modules?"
• Onboarding onto a Roblox project and need to understand the standard conventions
• Choosing between a flat script layout and a modular loader pattern

This document covers the Roblox data model, service hierarchy, script types, client-server communication, module patterns, framework options, folder organization, best practices, and anti-patterns.
