QBCore vs ESX vs Qbox: Which FiveM Framework to Pick in 2026

Choosing a framework is the first big decision when you set up a FiveM server, and also the hardest one to reverse. The QBCore vs ESX debate has been open for years, and Qbox has since joined the conversation as a serious third option. In this guide we compare all three without fanboyism: what each one offers, how they really differ, who each one suits and what your choice means when it is time to buy scripts.

What is a FiveM framework and why does it shape your whole stack?

A FiveM framework is the base everything else is built on: it handles player characters, money, jobs, items, permissions and communication between resources. Almost every script you install later depends on it, so installing qb-core or es_extended is not installing “just another script”. It is installing the nervous system of your server.

This has an enormous practical consequence. A mechanic script for QBCore calls functions like QBCore.Functions.GetPlayer, while its ESX equivalent uses ESX.GetPlayerFromId. They are not interchangeable without adaptation. See how even something as simple as adding money to a player from the server changes:

-- QBCore
local Player = QBCore.Functions.GetPlayer(source)
Player.Functions.AddMoney('bank', 500)

-- ESX Legacy
local xPlayer = ESX.GetPlayerFromId(source)
xPlayer.addAccountMoney('bank', 500)

-- Qbox
local player = exports.qbx_core:GetPlayer(source)
player.Functions.AddMoney('bank', 500)

Three frameworks, three different APIs for the same operation. And this repeats in every system: how jobs and grades are defined, the database structure, the character selection flow, the permissions system and even the format of inventory items. That is why the framework decides which scripts you can use, which tutorials help you, which developers can assist you and even which support community stands behind you.

Switching frameworks later is possible, but it costs time and money, so it is worth spending an afternoon deciding well now. If you are still building the server from scratch, remember the framework is one of the first pieces of the full process, from txAdmin to server.cfg, and everything else is built on top.

Where does each framework come from?

ESX is the veteran, QBCore is the dominant option today, and Qbox is the newer fork built on the ox stack. Knowing their origins explains their strengths: ESX has the oldest legacy, QBCore has the most coherent official ecosystem, and Qbox has the most modern core.

ESX, the veteran

ESX (es_extended) is the oldest roleplay framework still alive. It was born in the golden age of European roleplay servers and for years was the de facto standard. Its modern version, ESX Legacy, cleaned up much of the old code and increasingly relies on the ox ecosystem: ox_lib for utilities and UI, ox_inventory as the inventory and oxmysql as the database connector.

Its big asset is its legacy: thousands of scripts, tutorials and developers know ESX. Its big weight is that same legacy: a lot of old content uses outdated APIs and code quality varies widely.

QBCore, the current leader

QBCore grew out of the old qbus and became the reference framework of the English-speaking scene. Its qb-* ecosystem is huge and very coherent: qb-inventory, qb-garages, qb-policejob, qb-adminmenu and dozens of official resources covering almost everything a roleplay server needs at launch.

QBCore’s structure is popular because it is explicit: player data lives in PlayerData, items use metadata natively (important for stateful objects such as weapons with a serial number) and the official documentation is reasonable. Most of today’s premium script market is developed for QBCore first.

Qbox, the evolution on top of ox

Qbox is a community fork of QBCore born when some of its contributors decided to modernize the base without carrying legacy compatibility. Its core, qbx_core, is built directly on ox_lib and adopts ox_inventory as the standard inventory, with emphasis on performance, security and modern Lua practices.

The key detail: Qbox keeps a compatibility bridge with QBCore, so many qb-* scripts work on Qbox untouched or with minimal changes. That lets it tap into the QBCore ecosystem while it builds its own.

QBCore vs ESX vs Qbox: how do they compare side by side?

QBCore has the largest ecosystem and community, ESX Legacy has the longest history and a strong European base, and Qbox has the most modern core with the best out-of-the-box performance. The table below summarizes the five criteria that matter most when choosing.

Criterion	ESX Legacy	QBCore	Qbox
Learning curve	Medium; plenty of documentation but scattered and partly outdated	Low-medium; clear structure and decent official docs	Medium; requires knowing ox_lib and more modern concepts
Script ecosystem	Huge but aging; new content usually arrives via ox	The largest and most active in the premium market	Growing; inherits much of QBCore’s through the bridge
Performance	Good with the ox stack; mixed with old resources	Good by default, depends heavily on the qb-* resources you pick	Very good; the core is optimized by design
Community	Large, strong in Europe	The largest and most active worldwide	Smaller but technical and growing
Future	Stable, moderate development pace	Very established, continuous evolution	Modern project with clear technical direction

An honest warning about performance: the framework itself is rarely the bottleneck. A well-built ESX server with ox resources outperforms a QBCore server full of badly optimized scripts. What you see in resmon depends far more on the quality of each resource than on the framework logo.

Which framework should I choose for my server?

Choose QBCore if you start from scratch and want the least friction, ESX Legacy if your community already lives there, and Qbox if you prioritize performance and a modern ox-based core for a long-term project. Standalone resources work on all three, so they never lock you in.

Choose ESX if…

• Your target community or your roleplay references already use ESX.
• You already have experience with es_extended and the ox ecosystem.
• You want to take advantage of years of accumulated scripts, maps and documentation, accepting that you will have to filter out what is outdated.

Choose QBCore if…

• You are starting from zero and want the path of least friction: more scripts available, more recent tutorials, more developers on the market.
• You plan to buy premium scripts: most stores develop for QBCore first.
• You value a coherent official ecosystem where inventory, jobs and administration speak the same language.

Choose Qbox if…

• You care about performance and code cleanliness more than the raw number of available resources.
• You already work with ox_lib and ox_inventory and want a core that treats them as first-class citizens.
• You are building a long-term project and prefer a modern base even if it means a bit more initial work. More native Qbox scripts are being published, on top of everything it inherits from QBCore.

What about standalone? Standalone resources do not depend on any framework and work on all three. They are the safe option for utilities, UI systems or isolated mechanics, and a good way to reduce the coupling of your server.

What can I keep when migrating from one framework to another?

You keep standalone resources, maps and MLOs, vehicles, clothing and peds, and most of the ox stack. You lose framework-bound scripts such as jobs, shops and gangs, which need an equivalent version or manual adaptation, and your database needs migration. Switching on a live server is serious, but you do not lose everything.

Here is what can be reused:

• Standalone resources: HUDs, UI systems, utilities and minigames that do not touch the framework migrate unchanged.
• Maps and MLOs: 100% independent of the framework.
• Vehicles, clothing and peds: asset streaming resources do not depend on the framework either.
• The ox stack: if you use ox_lib, ox_inventory and oxmysql, you are halfway there when moving between ESX Legacy and Qbox, because both adopt them naturally.

What does not carry over: framework-bound scripts (jobs, shops, gangs, factions) need their equivalent version or manual adaptation, and the database requires migration because ESX and QBCore structure users, characters and items differently. The inventory is usually the most delicate point, because the item format and its metadata change between systems; in our comparison of the best FiveM inventory we explain those differences in detail.

The least painful route today is QBCore to Qbox: since it is a fork with a compatibility bridge, a large part of your qb-* resources keep working while you migrate the rest in phases.

A phased migration plan

If you decide to make the jump, do not do it all at once on a Friday night. The process that works best in practice is this:

1. Set up a test server with the new framework and a copy of your database. Never migrate directly in production.
2. Inventory your resources: classify each one as standalone (migrates as is), framework-dependent with an equivalent version available, or dependent with no equivalent (it will have to be adapted or replaced).
3. Migrate the data: characters, money, vehicles and items. Community tools exist for the most common routes, but always review the result by hand with several test accounts.
4. Test with your staff for at least a week: economy, jobs, inventory, police and every flow that touches money or items.
5. Announce the date, freeze the economy for a few hours and run the switch with a way back if something goes wrong.

Told like this it sounds like a lot of work, and it is. That is exactly why it pays to choose well the first time.

How does your framework affect buying scripts?

Your framework decides which scripts run on your server, so check three things before buying: declared compatibility with your framework and inventory, the dependencies it needs, and active maintenance. This is where the decision shows up in your wallet.

1. Declared compatibility: the product page should explicitly state support for your framework and your inventory. “QBCore compatible” does not always mean compatible with Qbox or ox_inventory, although more developers now publish multi-framework versions that detect the environment automatically.
2. Dependencies: many modern scripts require ox_lib or oxmysql. If your server still runs old resources, note it before paying.
3. Active maintenance: frameworks evolve and abandoned scripts break. Prioritize stores that offer free updates and real support.

Before you buy, check that a script names the frameworks it supports and its exact dependencies. The QBCore, ESX, Qbox and standalone pages explain what to look for in each case.

So, which one wins: QBCore, ESX or Qbox?

There is no universal winner. QBCore is the default for anyone starting in 2026 purely because of ecosystem size, ESX Legacy is still a solid choice if your community lives there, and Qbox is the technical bet for long-term projects that value a modern base on ox. All three are mature frameworks you can build a great server on.

The real difference is made by the quality of the resources you install on top and the care you put into your economy and administration. Whatever you choose, make it a strategic decision and not a cage.
