Introducing Mod Builder: AI-Powered Scripts for FiveM & Roblox

Today we're launching Mod Builder - a new feature in Sprixen that brings AI-powered asset and script generation to two of the biggest modding ecosystems: FiveM (GTA V multiplayer) and Roblox.

Until now, Sprixen focused on indie game developers building original games. Mod Builder expands that to the millions of developers building on top of existing platforms - a market worth over $1.5 billion annually in creator payouts (Roblox alone) and growing fast.

What is Mod Builder?

Mod Builder is a chat-driven development environment where you describe what you want and AI generates working code. It combines three things no other tool does together:

• Lua/Luau script generation - production-ready FiveM resources or Roblox experiences
• NUI interface design - custom HTML/CSS/JS overlays for FiveM (inventory, phone, HUD)
• 3D asset generation - models and props using Sprixen's existing TRELLIS pipeline

The AI understands FiveM architecture (client/server scripts, natives, events, NUI callbacks) and Roblox patterns (Services, RemoteEvents, DataStores, typed Luau). It doesn't just write generic code - it writes platform-native code.

Why FiveM & Roblox?

These two platforms represent massive, underserved developer communities:

• FiveM: 130,000+ concurrent players, 30,000+ active servers, and a creator economy estimated at $250-400M annually. Every server runs on Lua scripts that control the economy, jobs, UI, and mechanics. Server owners pay real money for good scripts on the Cfx Marketplace and Tebex.
• Roblox: 3.5 million active developers, 144 million daily active users, and $1.5 billion in annual creator payouts. Developers build experiences in Luau (a typed Lua variant) using Roblox Studio.

Both platforms use Lua-based scripting. Both have huge demand for quality content. And both have primitive AI tooling today - most developers still write everything from scratch or buy pre-made scripts.

How It Works

1. Choose Your Platform

Select FiveM or Roblox at the top of Mod Builder. For FiveM, choose your framework: QBCore, ESX, or Standalone. The AI adapts its code style and APIs accordingly.

2. Pick a Template or Start from Scratch

We ship with 8 ready-to-customize templates:

FiveM:

• Job System - markers, blips, animations, payment
• Inventory HUD - dark NUI with grid layout and drag & drop
• Phone UI - smartphone with apps and messaging
• Vehicle Shop - dealership with preview and purchase

Roblox:

• Obby Course - checkpoints, timer, DataStore leaderboard
• Tycoon - droppers, upgraders, collectors, rebirth system
• Combat System - sword combos, abilities, cooldowns
• Pet Simulator - egg hatching, rarity tiers, evolution

Or describe your idea from scratch and the AI generates all files.

3. Chat to Build & Iterate

The AI creates all necessary files in one response: fxmanifest.lua, client.lua, server.lua, config.lua, and HTML files for NUI. View the code with syntax highlighting, preview NUI overlays live, and iterate by chatting.

4. Export

Copy individual files or download everything. For FiveM, you get a resource folder ready to drop into your server. For Roblox, you get scripts organized by Roblox Studio service structure.

What Makes It Different

Several AI script generators exist for FiveM and Roblox (BLDR Chat, Intelliscripts, SuperbulletAI). Here's what Sprixen adds:

• Scripts + UI + 3D in one place - no other tool generates Lua code, NUI interfaces, and 3D models together
• Visual consistency - Sprixen's core differentiator. Assets generated in the same project share visual DNA
• Multi-platform - FiveM and Roblox in one tool (competitors serve only one)
• Framework-aware - QBCore, ESX, and Standalone output for FiveM. Typed Luau for Roblox
• Code quality - production-ready with config files, server validation, proper event naming

What's Coming Next

Mod Builder is launching in beta. Our roadmap includes:

• More templates (police MDT, housing, banking, shop systems)
• ZIP download for instant server deployment
• 3D model export optimized for FiveM (.ydr format)
• Roblox Studio MCP integration (connect directly to Studio)
• GTA 6 / Project ROME support when it launches (November 2026)
