What Is QBCore Framework?

QBCore (often written as qb-core) is one of the three major roleplay frameworks for FiveM, alongside ESX Legacy and the newer QBOX. Originally developed as a modern alternative to ESX, QBCore has grown into a fully featured framework used by thousands of servers in 2026.

Key characteristics of QBCore:

• Clean Lua architecture — Modular design with clear separation of concerns
• Built-in systems — Player management, jobs, gangs, inventory hooks, vehicle ownership
• Active development — Regular updates from the QBCore team and a large contributor base
• Growing ecosystem — Thousands of compatible scripts on GitHub and paid script platforms

If you are building a new FiveM server today, QBCore is one of the strongest choices — especially if you value clean code and active community support.

QBCore vs ESX vs QBOX — Quick Comparison

Feature	QBCore	ESX Legacy	QBOX
Architecture	Modern, event-driven	Classic, table-based	Modular, performance-first
Script Ecosystem	Large and growing	Largest	Smallest (new)
Learning Curve	Medium	Low	Medium-High
Performance	Good	Good	Best
Community Size	Very large	Largest	Growing
Job System Built-in	Basic	Basic	Basic
Active Development	Yes	Yes	Yes

All three frameworks provide a basic built-in job system with limited features. For a production roleplay server, most owners supplement the default system with a dedicated job management solution that provides in-game configuration, unlimited jobs, and advanced features like crafting, garages, and economy chains.

Essential QBCore Scripts Every Server Needs

Job System

QBCore ships with qb-core job definitions, but the built-in system is minimal — you define jobs in a config file and restart the server every time you change something. For a serious server, you need either:

• Custom Lua job scripts (requiring developer time), or
• A complete job management system like Jobs Creator that provides in-game creation, editing, grades, markers, shops, crafting, garages, armories, and boss menus — all without code

Jobs Creator is fully compatible with QBCore and uses the framework's native job and gang systems under the hood.

Inventory

The two most popular QBCore-compatible inventories are:

• ox_inventory — Modern, performant, and feature-rich. Uses metadata for item properties.
• qs-inventory — Feature-focused with a polished UI. Good drag-and-drop support.
• qb-inventory — The default QBCore inventory. Functional but more limited.

Vehicle System

• qb-garages — Default garage system for QBCore
• jg-advancedgarages — Advanced alternative with impound, key system, and more

Phone System

• qb-phone — Default phone with basic apps
• qs-smartphone — Premium phone with advanced features
• lb-phone — Popular premium option with extensive app support

Housing

• qb-houses — Basic housing system
• bcs-housing — Advanced housing with interior customization

How to Install QBCore Scripts Properly

Every QBCore script follows the same installation pattern:

Step 1: Download

Download the script from its source (GitHub, Tebex, or another platform). Extract the .zip if needed.

Step 2: Place in Resources

Move the script folder into your server's resources/ directory. Many servers organize resources into subfolders:

resources/
  [qb]/
    qb-core/
    qb-radialmenu/
    qb-target/
  [standalone]/
    ox_lib/
    ox_inventory/
  [jobs]/
    advanced-jobs-creator/

Step 3: Add to server.cfg

Add ensure resource-name to your server.cfg file. Order matters — dependencies must load before the scripts that need them:

# Core (must load first)
ensure qb-core
ensure ox_lib

Database
ensure oxmysql

Inventory and items
ensure ox_inventory

Jobs and economy
ensure advanced-jobs-creator

Step 4: Import SQL

Many scripts include a .sql file. Import it into your database using phpMyAdmin, HeidiSQL, or the command line:

mysql -u root -p your_database < script_name.sql

Step 5: Configure

Open the script's config.lua (or config/ folder) and adjust settings for your server. With Jobs Creator, all configuration happens in-game through the tablet — no file editing needed.

Performance Tips for QBCore Servers

1. Use ox_lib — It provides optimized replacements for common QBCore functions like notifications, input dialogs, and targeting.
2. Avoid redundant resources — Don't run two inventory systems or two phone scripts. Each adds tick time.
3. Monitor resmon regularly — See our complete resmon optimization guide for step-by-step instructions.
4. Update dependencies — Outdated versions of oxmysql, ox_lib, and qb-core often contain performance bugs that have been fixed in newer releases.
5. Choose optimized scripts — Premium scripts like Jobs Creator are built with performance as a priority, maintaining 0.00 ms idle resmon.

Common QBCore Script Issues and Fixes

Issue	Cause	Fix
"attempt to index a nil value (field '?')"	Script loaded before qb-core	Move ensure qb-core above the script in server.cfg
"No such export"	Missing dependency (often ox_lib)	Install the required dependency
Players have no money after restart	Database not properly connected	Check oxmysql connection string and SQL imports
Job not showing in-game	Job not registered in shared.lua or not ensured	Add job definition or use Jobs Creator for in-game management
Inventory items missing	Item metadata not in ox_inventory/data/items.lua	Register items in the inventory configuration
"Resource yielded during load"	Async operation in resource startup	Check fxmanifest.lua for correct script order
