What Is a FiveM Framework?

A FiveM framework is the core engine that powers your roleplay server. It handles everything players depend on day-to-day:

Player jobs, salaries & society systems
Inventories & item management
Banking, shops & economy
Vehicle ownership & garages
Admin tools & permission systems
Integration with scripts, MLOs, and custom resources

If MLOs are what your world looks like, your framework is what makes it work. The two most widely used frameworks in 2026 are ESX and QBCore — and choosing between them is the most important decision you'll make when setting up your server.

Why Your Framework Choice Matters

Benefit	Why It Matters
Script compatibility	Most scripts are written for one framework — picking wrong means fewer resources
Community support	Larger communities = faster help when things break
Performance	Modern frameworks handle player load and sync differently
Developer ecosystem	More devs familiar with your framework = easier to hire help
Long-term stability	Active maintenance means security patches and GTA updates are covered

Did you know? Every script and MLO on FiveVault is tagged by framework — ESX, QBCore, QBOX, OX Core, or Standalone. Browse all scripts →

Prerequisites

Before you start, make sure you have:

Requirement	Details
FiveM server	Any artifact (recommended: build 6016+ for modern frameworks)
MariaDB / MySQL	Both frameworks require a database (MariaDB 10.6+ preferred)
txAdmin	Highly recommended for managing either framework
server.cfg access	To add `ensure` lines and configure startup order
Basic server knowledge	You should know how to upload resources and edit configs

Step 1: Understand What Each Framework Actually Is

ESX (es_extended) is the oldest and most widely used FiveM framework. Originally released around 2017, it introduced jobs, inventories, and society systems to FiveM RP. It's mature, battle-tested, and has an enormous library of compatible scripts. QBCore launched as a modern alternative around 2020. It was built with cleaner code architecture, better performance, and a more active open-source community. It quickly became the go-to for new servers wanting a fresh start.

ESX    → Mature, massive script library, older codebase
QBCore → Modern, cleaner code, fast-growing ecosystem

Pro tip: If you're using ESX, always use ESX Legacy — a community-maintained rewrite that modernized the original codebase. Never use the original unmaintained es_extended.

Step 2: Compare the Script Ecosystems

This is where most server owners get stuck. The script you want might only exist for one framework.

ESX script count (2026): 10,000+ resources on GitHub, CFX forums, and marketplaces QBCore script count (2026): 6,000+ resources, but growing faster year-over-year

You can check a script's framework compatibility by looking at its fxmanifest.lua:

lua

dependency 'es_extended'   -- ESX only
dependency 'qb-core'       -- QBCore only
-- No dependency = likely standalone (works on both)

Step 3: Set Up Your Chosen Framework

For QBCore:

Download from github.com/qbcore-framework/qb-core
Place in: resources/[qb-core]/qb-core
Add to server.cfg: ensure qb-core
Install oxmysql for database support

For ESX Legacy:

Download from github.com/esx-framework/esx_core
Place in: resources/[esx]/es_extended
Add to server.cfg in this order:

ensure oxmysql
ensure es_extended

Import the included .sql file into your database

Pro tip: Both frameworks have official recipe installers via txAdmin — this is the fastest way to get a clean base server running without manually placing files.

Step 4: Choose Based on Your Server's Goals

Not sure which to pick? Use this as a guide:

Situation	Recommended Framework
Starting fresh in 2026	QBCore — modern, better long-term
Migrating an existing server	ESX — less friction, preserves compatibility
Need a massive plug-and-play script library	ESX
Building custom scripts with a dev team	QBCore
Want the strictest code quality standards	QBOX (QBCore fork)
Need framework-agnostic flexibility	OX Core

Framework Compatibility

Framework	Compatibility Notes
Standalone	Works on every server. No extra config needed.
ESX Legacy	Best compatibility with existing scripts. Use `es_extended` from the ESX-Framework org only.
QBCore	Best for new servers. Growing library, excellent OX integration.
QBOX	A stricter, quality-controlled fork of QBCore. Fully QBCore-compatible.
OX Core	Standalone core. Pairs well with both ESX and QBCore via `ox_lib`.

How to check a script: Open its folder. If you see dependency 'qb-core' or dependency 'es_extended' in fxmanifest.lua — it's framework-specific. If you see neither — it's standalone.

Troubleshooting Common Framework Issues

❌ "ESX not initialized" on a QBCore server

Solution: You've installed an ESX-only script. Check fxmanifest.lua for dependency 'es_extended' and find the QBCore equivalent, or use a bridge resource.

❌ QBCore player data returns nil

Solution: The player hasn't fully loaded yet. Ensure your logic runs server-side only after the QBCore:Server:PlayerLoaded event fires.

❌ ESX jobs not saving to database

Solution: Your SQL import is incomplete. Re-import es_extended.sql and confirm oxmysql starts before es_extended in server.cfg.

❌ txAdmin recipe fails mid-install

Solution: Usually a GitHub rate limit or missing dependency. Wait 60 seconds and retry. If it fails again, manually install the core resource.

❌ "You lack the required entitlement" error

Solution: Your server's license key in server.cfg doesn't match your CFX account. Log into keymaster.fivem.net and verify.

❌ Scripts conflict after installing a second framework

Solution: Never run ESX and QBCore on the same server — they will conflict. Pick one and stick with it.

Recommended Resources for Your Framework

Resource	Type	Framework
oxmysql	Database bridge	Both
ox_lib	Utility library	Both
ox_inventory	Inventory system	Both
qb-target	Interaction system	QBCore
ox_target	Interaction system	Both
esx_society	Job society system	ESX

Final Tips

✅ New server in 2026? Default to QBCore — it's where the ecosystem is heading
✅ Always use ESX Legacy — never the original unmaintained es_extended
✅ Always use oxmysql as your database bridge — works with both frameworks
✅ Don't mix frameworks — running ESX and QBCore on the same server causes conflicts
✅ Test on a dev server before switching frameworks on a live production server
✅ Check FiveVault's framework filter before downloading any script or MLO
✅ Join the official Discords — QBCore and ESX both have large, active support communities

Frequently Asked Questions

Q: Can I switch from ESX to QBCore without losing player data?

A: Not directly. Player data structures differ between frameworks. You'd need a custom migration script — it's doable but requires a developer.

Q: Which framework do most FiveVault scripts support?

A: FiveVault has strong coverage for both. ESX has more total scripts, but QBCore is growing fastest. Always use the framework filter when browsing.

Q: Is QBCore free?

A: Yes. QBCore is fully open-source under the GPL license. All core resources are free on GitHub.

Q: What is QBOX and should I use it?

A: QBOX is a stricter, more quality-controlled fork of QBCore. Good choice if you want cleaner code standards, but it has a smaller script ecosystem than mainline QBCore.

Q: Will ESX be supported in 2026 and beyond?

A: Yes. ESX Legacy is actively maintained and isn't going anywhere. Thousands of servers depend on it and the community remains large and active.
