What is FiveM development and what does a FiveM developer do?

FiveM extends Grand Theft Auto V into a moddable multiplayer framework. A FiveM developer writes Lua for CitizenFX, builds NUI in HTML or React, connects MySQL via oxmysql, integrates ESX or QBCore (or custom frameworks), and optimizes for OneSync population, entity limits, and server tick performance.

Do you work with ESX, QBCore, Qbox, and ox_lib on FiveM servers?

Yes. PiTyUs ships features across ESX Legacy-style economies, QBCore and Qbox stacks, ox_lib notifications and input dialogs, ox_inventory patterns where needed, and fully custom frameworks when design goals go beyond off-the-shelf templates.

Can you build NUI (in-game browsers) for FiveM?

NUI is a core specialty: React, Vue, or Vite-built panels, shops, MDTs, crafting UIs, and admin tools with accessible markup, responsive layouts, and tight Lua↔JS bridges using NUI callbacks and message contracts.

How do you approach FiveM server performance and OneSync?

Profiling-first: reducing redundant events, batching state updates, respecting entity and player bucket rules, tuning population zones, and validating database queries. The goal is stable frame time for clients and predictable server ms under peak concurrent players.

Do you offer website and landing page work for FiveM brands?

Yes. Next.js and modern static sites for server brands, waitlist pages, rules and lore sites, and documentation hubs—SEO-oriented structure, fast Core Web Vitals, and design systems that match in-game identity.

What is CitizenFX scripting and how does it relate to FiveM?

CitizenFX is the runtime behind FiveM. Scripts use Lua with FiveM natives for entities, players, and world state. Resources are packaged with fxmanifest.lua, loaded by the server, and coordinated with client and server contexts.

How much does a custom FiveM script cost?

Pricing is scope-based rather than fixed. A small standalone resource is very different from a multi-job economy, a full NUI inventory, or an ESX-to-QBCore migration. Share the framework, the feature list, and the deadline, and you get a clear estimate with milestones before any work starts—no surprise scope creep.

Can you fix, optimize, or refactor an existing FiveM server?

Yes—server audits and refactors are a core service. That includes OneSync and server-tick profiling, removing redundant events and net traffic, fixing resource conflicts, hardening exploitable handlers, cleaning up oxmysql queries, and upgrading aging ESX or QBCore stacks without breaking live gameplay for your players.

Should I use ESX or QBCore for my GTA V roleplay server?

Both are solid—the right choice depends on your resource library, your team's familiarity, and how much custom work you plan. QBCore and Qbox ship a more modern core and tooling out of the box; ESX Legacy has a huge ecosystem and battle-tested scripts. PiTyUs builds on all of them, and on fully custom frameworks when off-the-shelf templates limit your design.

Can you convert or bridge scripts between ESX, QBCore, and Qbox?

Yes. Framework conversions and bridges are common work: porting jobs, inventories, and economies between ESX and QBCore/Qbox, wiring ox_lib and ox_inventory compatibility layers, and keeping shared exports stable so the rest of your server keeps working during the migration.

Do you build custom FiveM HUDs, phones, and inventory UIs?

NUI is a specialty. Custom HUDs, phone apps, inventories, crafting tablets, police MDTs, and admin panels in React, Vue, or vanilla CEF—responsive, accessible, and tuned for 1080p in-game rendering with tight Lua↔JS callback contracts and optimistic UI where it helps.

How can I contact PiTyUs for a FiveM commission?

Join the PiTyUs Discord at https://discord.gg/64a26MK4jZ, open a support ticket there, or send a direct message to the user pityus on Discord. Describe your scope, framework (ESX, QBCore, or custom), timeline, and whether you need NUI, database work, or full-stack delivery. This site does not list a public email or GitHub for inquiries.

What is CRM Development (crmfivem.dev) and how is PiTyUs involved?

CRM Development is an affiliated FiveM platform at https://crmfivem.dev/ offering server-oriented packages, custom scripts, and ESX/QBCore ecosystem resources, with secure role-based access and a cohesive design system. PiTyUs leads the product UI and front-end engineering; the live site credits PiTyUs in the footer as the design partner.

Engineering

Using Git to manage FiveM resources

Put a FiveM server or script under Git: what to commit and what to ignore, a .gitignore for server-data, keeping licence keys and tokens out of the repo, large streamed assets and Git LFS, branches for testing, private GitHub repos, and deploying with git pull.

Overview

“Who changed the garage config?” and “it worked yesterday” stop being mysteries once your server is in Git. Every change has an author, a date and a message, broken edits can be undone in seconds, and a test server can run a branch before it reaches players.

01Setting up the repository

In your server-data folderbash

git init
git add .
git commit -m "Initial server state"
git branch -M main
git remote add origin [email protected]:you/your-server.git
git push -u origin main

What to ignore

.gitignoretext

# FXServer generated
cache/
*.log

# txAdmin data
txData/

# secrets
secrets.cfg
*.env

# node / build output of NUI projects
node_modules/
web/dist/

# OS junk
Thumbs.db
.DS_Store

Whether to commit NUI build output depends on your deploy: if the server does not build, commit the built files and ignore only node_modules.

Keeping secrets out

server.cfg (committed)cfg

exec secrets.cfg
ensure oxmysql
ensure ox_lib

secrets.cfg (ignored)cfg

sv_licenseKey "..."
set mysql_connection_string "mysql://fivem:...@localhost/fivem"
set discord_bot_token "..."

Large streamed assets

Vehicle and map packs can be gigabytes. GitHub warns on files over 50 MB and blocks files over 100 MB. Use Git LFS for large binary assets, or keep asset packs in a separate storage and only version scripts and configs.

A simple workflow

Create a branch for a change: git switch -c garage-rework.
Test it on a local or test server — see local development server.
Commit with a clear message, merge into main.
On the live server: git pull, then ensure or restart the changed resources.

Paid and escrowed resources

Purchased resources are licensed to you; putting them in a public repository redistributes them. Keep server repos private, and never publish escrowed files — see asset escrow explained.

Frequently asked questions

Should I put my FiveM server in Git?

Yes — at least resources and configs. It gives you history, undo and safe deploys.

What should a FiveM .gitignore contain?

cache/, logs, txData/, secret files, node_modules/ and build output you do not deploy.

How do I keep my license key out of GitHub?

Put it in a secrets.cfg that server.cfg execs, and add that file to .gitignore.

Can I push large vehicle packs to GitHub?

Files over 100 MB are blocked. Use Git LFS or store large assets elsewhere.

Need this built, not just explained?
