What is QBCore?
QBCore (QB-Core) is a widely used FiveM roleplay framework that handles player management, jobs, inventory, vehicles, banking, housing, and economy systems. Server owners choose it because the ecosystem has many tutorials, add-on resources, and familiar exports/events for developers. FiveMX groups QBCore-friendly resources across police, jobs, vehicles, drugs, HUD, and free mods so owners can compare options without digging through unrelated framework pages.
Are QBCore scripts compatible with ESX?
No, QBCore scripts are not compatible with ESX servers and will not function without significant rewriting. Each framework uses entirely different player data structures, event naming conventions, export functions, and database schemas. A QBCore script calls exports like QBCore.Functions.GetPlayerData() while ESX uses ESX.GetPlayerData() — these are fundamentally different APIs that cannot be swapped without modifying the entire script. Inventory systems, job definitions, item handling, and money management all work differently between the two frameworks at the code level. If you are migrating an existing server from ESX to QBCore, FiveMX offers an ESX to QBCore converter tool that helps translate common patterns. Many popular scripts on FiveMX are also available in both QBCore and ESX versions, clearly labeled on each product page so you can select the correct framework version before downloading.
How do I install QBCore scripts?
Installing QBCore scripts follows a consistent five-step process. First, download and extract the script ZIP file to your server's resources folder, keeping the folder name intact. Second, open your server.cfg and add 'ensure [script-name]' after your QBCore core resources to ensure proper load order. Third, import any included SQL files into your MySQL or MariaDB database using HeidiSQL or phpMyAdmin to create the required tables. Fourth, add any new job entries or shared items to your qb-core/shared files — many scripts require job grades or item definitions registered in QBCore's shared configuration. Fifth, open the script's config.lua to adjust settings like prices, cooldowns, permissions, and framework-specific options, then restart your server. Always read the installation documentation included with each script. FiveMX provides step-by-step guides with every QBCore script download to make setup straightforward.
What are the most essential QBCore scripts?
Most QBCore servers should start with a small, coherent stack: phone, inventory, HUD, banking, garage, admin tools, police, EMS, dispatch, jobs, and housing. Add drugs, heists, businesses, racing, courts, and prisons only after the foundation works under load. The best stack is not the largest one; it is the one where resources share compatible dependencies and do not duplicate core systems.
Where can I find safe QBCore scripts to download?
Download QBCore scripts from sources that show documentation, dependencies, update history, and support expectations clearly. The FiveM community has had problems with compromised scripts, so review server-side files before installing anything: watch for obfuscated Lua, unknown HTTP calls, dynamic code execution, and SQL changes you do not understand. Use a staging server before production and keep backups before importing scripts into a live database.
What is the difference between QBCore and QBOX?
QBOX is the next-generation evolution of the QBCore framework, forked from QBCore's codebase with significant performance optimizations, improved inventory systems, and a more modular architecture. QBOX maintains backward compatibility with most existing QBCore scripts while introducing modern Lua patterns, reduced memory usage, and faster event handling that can noticeably improve server tick rates. The framework's modular design makes it easier to swap individual components without affecting the rest of your server setup. If you are starting a brand-new server in 2026, QBOX is worth strong consideration for its performance advantages — benchmarks show 15 to 30 percent lower resource consumption compared to standard QBCore in typical configurations. However, QBCore still maintains the larger script ecosystem with more third-party resources available. Many scripts that work on QBCore will run on QBOX without modification. FiveMX labels scripts with both QBCore and QBOX compatibility tags to help you find resources that match your framework.
How many resources should a QBCore server run?
A well-optimized QBCore server typically runs between 50 and 150 resources without performance degradation, though the exact number depends entirely on script quality rather than quantity. One poorly coded script consuming 3 to 5 milliseconds of server time per frame causes more lag than 30 well-optimized scripts running at 0.01 milliseconds each. Use txAdmin's built-in resource monitor to identify which scripts consume the most CPU time, and address anything above 0.5 milliseconds under load. Consolidate overlapping functionality — running two inventory systems or three notification frameworks wastes resources and creates conflicts. Load order in your server.cfg matters: QBCore core must load first, followed by dependency libraries like oxmysql, then feature scripts in logical groups. Database connection pooling through oxmysql prevents connection exhaustion when many scripts query MySQL simultaneously. FiveMX includes performance benchmarks on product pages, helping server owners choose scripts that maintain healthy server tick rates.
