Best FiveM Frameworks in 2026 - ESX, QBCore, Qbox, vRP, and OX Compared

ESX (Extended Roleplay Script, also known as ESX Legacy) has been the most widely used FiveM framework since 2017. With over 10,000 active servers and 500,000+ daily players, no other framework matches ESX's reach. Started by JapaneseAngel and now maintained as ESX Legacy by the community on GitHub, it is 100% free and open-source. Key strengths: largest resource ecosystem by far (thousands of compatible scripts on the FiveM forums and GitHub), extensive documentation at docs.esx-framework.org covering every function and event, massive Discord community with 13,000+ developers providing support, built-in job system with police, EMS, mechanic, taxi, and customizable civilian roles, and economy system with banking, black money, and society accounts. ESX Legacy (1.10+) has been modernized with 40% faster SQL queries and a refactored event system. Best for: servers that need maximum resource compatibility and rapid deployment using existing scripts.

QBCore emerged as a clean, modern alternative to ESX and has grown into one of the FiveM docs' officially recognized frameworks. It uses a Lua-based architecture that is lighter than ESX, with faster boot times and lower resource CPU usage. Key strengths: cleaner modern code structure with better error handling, built-in integration with ox_lib and ox_inventory (the industry standard inventory system), comprehensive documentation at docs.qbcore.org covering installation, configuration, and development, and a rapidly growing resource ecosystem that covers most essential RP features. QBCore uses a modular design with well-organized shared configuration files. Best for: new servers starting in 2026 that want clean foundations and don't need ESX's massive legacy script library. The framework overhead is notably lower than ESX, making it better suited for servers with 64+ concurrent players.

Qbox is the newest officially recognized framework on the FiveM docs, created on September 27, 2022. It started as a QBCore fork with the goal of improving upon QBCore while maintaining backwards compatibility. Today, Qbox strives to be much greater, deeply integrating Overextended's resources (OX Inventory, OX Target, ox_lib) into its core. Key strengths: 99% backwards-compatible with existing QBCore scripts (making migration smoother than switching to ESX or OX Core), utilizes best-in-class Overextended resources natively, built-in multicharacter, queue system, and multijob support, and active development with frequent updates. The framework is not affiliated with the Overextended team but leverages their resources extensively. Migration from QBCore involves updating job grades to numeric format, running a SQL migration, and updating server config files. Best for: QBCore server owners wanting to modernize, new servers wanting QBCore compatibility with OX resource integration, and communities wanting built-in multijob without external scripts.

vRP (vRP Framework) is the lightest officially recognized FiveM framework, designed for simplicity and performance. It uses Lua-based configuration files rather than a large module system, making it accessible for server owners without extensive programming experience. Key strengths: minimal resource overhead makes it the fastest framework for small to medium servers, simple folder-based resource management, easy to set up and configure with clear documentation, and popular in European RP communities. The tradeoff is a smaller resource ecosystem compared to ESX and QBCore, fewer modern features, and less active development. Best for: small servers (<32 slots), European communities where vRP is well-established, quick experimental servers, and server owners who prioritize simplicity over feature richness.

OX Core is built by the Overextended team (overextended.dev), the creators of OX Inventory, OX Target, OX MySQL, and ox_lib - tools that have become industry standards used across frameworks. OX Core itself is a modern, TypeScript-based framework with the cleanest architecture and best developer experience available. Key strengths: seamless integration with the entire Overextended ecosystem, modern TypeScript definitions for type-safe development, best-in-class inventory (OX Inventory) and interaction (OX Target) systems built-in, and active development by the team that sets standards for the entire FiveM community. However, OX Core is NOT listed on the official FiveM docs framework page - it is more accurately described as the foundation for the Overextended ecosystem of tools rather than a standalone RP framework in the traditional sense. Many servers use Overextended tools (OX Inventory, OX Target, ox_lib) with other frameworks like ESX, QBCore, or Qbox. Best for: developers who want the most modern stack, are comfortable writing TypeScript/Lua, and plan to build custom systems rather than relying on pre-built resources.

ESX Legacy: Largest community (13,000+ Discord members), most resources, best for traditional RP with maximum compatibility. Best choice if you want ready-made scripts for every possible feature. QBCore: Cleaner code, better performance, growing ecosystem, strong documentation at docs.qbcore.org. Best choice for new servers prioritizing clean foundations over maximum script availability. Qbox: QBCore improved with Overextended integration, 99% QBCore script compatibility, built-in multicharacter and multijob. Best choice for QBCore owners wanting to upgrade, or new servers wanting the best of both worlds. vRP: Lightest weight, simplest to learn, smallest ecosystem. Best for small communities and European servers. OX Core: Most modern architecture, smallest ecosystem, requires development skills. Best for developers building custom servers from scratch. Our top recommendation: ESX for maximum compatibility, QBCore for performance, Qbox for the modern sweet spot with QBCore compatibility plus OX integration.
