ESX vs QBCore vs QBox: Which Framework Should You Use in 2026?

Guides · 8 min read · Published: 2026-05-10 · Updated: 2026-06-08

If you have spent any time in FiveM server development communities, you have seen this argument play out hundreds of times. ESX loyalists say QBCore is bloated. QBCore fans say ESX is outdated. QBox supporters say both of the others are unmaintained. Everyone has an opinion, and almost none of them are based on anything measurable.

I have built and maintained servers on all three. Here is what actually matters when you are making this decision in 2026.

What a framework actually does

A FiveM framework is a shared Lua library that gives your scripts a common language. Instead of every resource reinventing how to give a player cash, a job, or an inventory item, the framework standardises it. ESX exports functions like ESX.GetPlayerData(). QBCore uses QBCore:GetCoreObject(). QBox uses ox_core functions.

The framework handles: player data persistence (MySQL), job systems, money handling, identity, and the event bus that all your resources communicate through. When you install a paid script, it targets one of these frameworks — which is why picking the right one matters before you buy anything.

ESX

ESX is the oldest of the three, originally developed around 2018. It has by far the largest ecosystem of available scripts — both free and paid. If you can think of a feature, someone has probably built it for ESX. The documentation is patchy in places, but the community on the official ESX Discord is huge and questions get answered quickly.

The knock against ESX is that the core codebase carries a lot of legacy decisions. Some older ESX scripts use patterns that are genuinely expensive in resmon terms. The modern es_extended (ESX 1.9+) has cleaned a lot of this up, but you will still encounter old scripts that have not been updated and drag your server performance down.

TIP: If you are starting out and want access to the widest library of free scripts to build your server without a massive budget, ESX is still the safest choice in 2026. The ecosystem depth is unmatched.

QBCore

QBCore launched around 2020 as a more structured alternative to ESX. It enforces cleaner patterns — shared objects, consistent event naming, and a well-documented API surface. Servers built on QBCore tend to feel more polished because the framework nudges you toward better code.

QBCore also has excellent txAdmin integration, and the qb-target / qb-menu ecosystem is a joy to work with once you know it. Resmon on a well-built QBCore server is generally lower than a comparable ESX setup, because QBCore never accumulated the legacy baggage.

The downside: QBCore has fractured somewhat. The "official" QBCore organisation went quiet for a period, and several forks appeared (QBox being the most prominent). The script ecosystem is smaller than ESX, and you will hit gaps where you need to port an ESX script or write something yourself.

QBox

QBox is the youngest of the three and positions itself as a clean reimplementation of QBCore using modern Lua practices and ox_lib as its dependency backbone. Instead of maintaining its own inventory, targeting, and menu systems, QBox delegates to ox_inventory, ox_target, and ox_lib — resources that are maintained separately and used across all three frameworks.

This is a genuinely smart approach. ox_lib is some of the best-maintained Lua code in the FiveM space. By building on top of it, QBox benefits from those improvements automatically. Resmon on a QBox server is the lowest of the three when everything is set up correctly.

WARNING: QBox has the smallest script ecosystem of the three. If you need a specific feature on day one, you may find yourself writing custom code. This is a better choice for experienced developers than for people building their first server.

Head-to-head: what actually matters

• Script availability — ESX wins. If you need it, it exists somewhere.
• Code quality and structure — QBCore and QBox are roughly equal, both ahead of legacy ESX.
• Resmon / performance — QBox slightly edges QBCore, both beat an unoptimised ESX setup.
• txAdmin compatibility — all three work well with txAdmin. No difference.
• Community support — ESX has the largest absolute community; QBCore has strong Discord presence; QBox is smaller but very active on GitHub.
• Long-term maintenance — ESX is in active development. QBCore has active forks. QBox is actively maintained. None of them are going away.

Which should you pick?

Start with what your team knows. If someone on your team has built servers before, use their framework — the productivity gain from familiarity outweighs almost any technical difference between the three.

If you are starting fresh with no existing knowledge: pick QBCore. It has a large enough ecosystem to build a full server, enforces good practices from the start, and has excellent documentation. ESX is not a bad choice either — just be selective about which scripts you install and avoid anything that has not been updated in two or more years.

QBox is worth considering if you have Lua experience, care deeply about performance, and are comfortable with a smaller selection of ready-made scripts.

INFO: All Revo Scripts are compatible with ESX, QBCore, and QBox out of the box. You do not need to switch frameworks to use our scripts — they detect your setup automatically.
