What is QBCore?
QBCore (QB-Core) is the most popular FiveM roleplay framework in 2026, providing the complete foundation that every other script on your server depends on. It handles player management, job systems, inventory, housing, vehicles, banking, and economy through a modern, event-driven Lua architecture designed for performance and maintainability. QBCore replaced the older ESX framework as the community's preferred choice due to its cleaner codebase, better resource efficiency, and highly active development community. The framework uses standardized exports and events that make third-party scripts more reliable and easier to integrate. Its built-in systems include multi-character selection, apartment management, gang territories, and a flexible item framework that script developers build upon. QBCore's documentation and Discord community are among the most active in the FiveM ecosystem. VertexMods carries hundreds of verified QBCore scripts across categories like police, jobs, vehicles, drugs, and HUD — all tested for QBCore compatibility before listing.
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, VertexMods offers an ESX to QBCore converter tool that helps translate common patterns. Many popular scripts on VertexMods 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. VertexMods provides step-by-step guides with every QBCore script download to make setup straightforward.
What are the most essential QBCore scripts?
Every serious QBCore roleplay server needs a core set of scripts that create the foundation for immersive gameplay. A police job with MDT integration (such as qb-policejob or premium alternatives) provides law enforcement mechanics including arrests, evidence collection, and dispatch. An advanced inventory system replaces the default with drag-and-drop functionality, weight limits, and crafting support. A phone app handles player communication, banking, social media, and job notifications. A housing or apartment script gives players property ownership and interior customization. An advanced garage system manages vehicle storage, impound mechanics, and dealership purchases. A drug manufacturing chain adds illegal economy depth with growing, processing, and distribution stages. A banking and ATM script rounds out the economy with transfers, loans, and transaction history. VertexMods hosts verified versions of all these essential QBCore scripts, each security-reviewed and performance-tested.
Where can I find safe QBCore scripts to download?
Safe QBCore scripts should only be downloaded from verified marketplaces that manually review every submission for malicious code. The FiveM community faces a persistent problem with backdoored scripts — resources that appear legitimate but contain hidden code granting attackers admin access to your server, leaking your database including player IPs and Discord tokens, or injecting cryptocurrency miners that consume server CPU. Common distribution vectors for compromised scripts include random GitHub forks, Discord direct messages, unverified Tebex stores, and suspiciously free versions of known premium resources. Red flags include obfuscated or encoded Lua code, scripts that make HTTP requests to unknown external servers, and resources that request unnecessary file system permissions. Always review server-side files before installing any script, looking for base64-encoded strings, external API calls, or dynamic code execution. VertexMods security-scans every QBCore script before listing, making it a trusted source for safe downloads.
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. VertexMods 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. VertexMods includes performance benchmarks on product pages, helping server owners choose scripts that maintain healthy server tick rates.
