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.

Business

A portfolio that wins FiveM work

Build a FiveM developer portfolio: what server owners look for, showcase videos, open-source samples on GitHub, case studies with performance numbers, a clear list of services and stack, testimonials, and where to publish it.

Updated 11 Sept 20268 min readBy PiTyUs · FiveM developer

Overview

Server owners hiring a developer have been burned before: missed deadlines, laggy scripts, developers who vanish. A good portfolio answers their fears before they ask — it shows finished work, proves quality with numbers, and makes it obvious how to work with you.

What clients look for

Finished, working systems — not tutorials.
Evidence of performance (idle resmon, tested with players).
Framework experience matching theirs (ESX, QBCore, Qbox).
Communication: clear scope, updates, deadlines.
Security awareness — see secure server events.

What to include

Piece	Why
30–60 s videos per project	Shows the result in seconds
2–3 open-source repos	Proves code quality
Short case studies	Shows how you think and deliver
Stack and services list	Clients see the fit immediately
Testimonials	Social proof from real servers

A case study template

The problem: “The server’s garage script cost 1.2 ms and duplicated cars.”
The solution: what you built or changed, and why.
The result: “0.02 ms idle, zero duplicates in three months, 180 players peak.”
A short clip or screenshot.

Where to publish

A personal site or a single page (with your videos embedded), GitHub for code, a Tebex store for products, and a Discord server for clients. Keep the same name everywhere so people can find you. Contracts and pricing: freelance contracts.

Frequently asked questions

What should a FiveM developer portfolio include?

Short videos of finished work, a few open-source samples, case studies with performance numbers, your stack and services, and testimonials.

Do I need a website?

Not strictly, but one page that collects videos, repos and contact details makes you look far more professional.

Should I share code publicly?

Share a few clean examples. Clients want proof you write maintainable code.

How do I get my first clients?

Release useful free resources, help in communities, and turn every small job into a case study.

Need this built, not just explained?

Ten years of FiveM work, from Lua to NUI

Custom resources, React NUI, ESX / QBCore / Qbox integration, OneSync performance audits and security reviews — plus the websites and SEO around your server brand.
