Choosing a framework is one of the biggest decisions when building a FiveM roleplay server. In 2026 there are three serious contenders: ESX, QBCore and Qbox. Here's an honest comparison of performance, script ecosystem, ease of use and active development to help you pick the right one.

ESX — the most-used framework

ESX (EssentialMode Extended) has been the dominant FiveM framework since 2017-2018 and still has the largest server count and the biggest library of ready-made scripts. It is also remarkably efficient — community benchmarks show ESX using noticeably less CPU than both QBCore and Qbox. The trade-off is that some older ESX resources are less structured and unoptimised. Pick ESX if you want maximum script availability and proven performance.

QBCore — mature but slowing down

QBCore launched in 2020 with cleaner code and a more roleplay-focused design than ESX, and it built a huge ecosystem of free and premium scripts. However, in 2026 core QBCore development has largely stalled. It's still perfectly usable if you already have a server invested in it, but new servers should think carefully before starting fresh on it.

Qbox — the modern QBCore successor

Qbox is a community fork of QBCore built for modern FiveM: Lua 5.4, native integration with the ox ecosystem (ox_lib, ox_inventory, ox_target) and roughly 25-40% lower CPU usage than QBCore. Crucially, Qbox is backwards-compatible with most QBCore resources, so the existing script library mostly still works. It ships with ox_inventory by default, avoiding one of the most common beginner mistakes. Qbox is the fastest-growing framework and the recommended path for a brand-new modern RP server.

Quick recommendation

  • Choose ESX if you're new, want the widest selection of ready-made scripts, or care most about raw performance.
  • Choose Qbox if you're building a fresh modern roleplay server in 2026 and want clean code + the ox ecosystem.
  • Stay on QBCore only if you already have a server heavily invested in it.

Whatever you choose, buy scripts that explicitly support your framework. At W-Development every script lists its ESX / QBCore / Qbox compatibility so you never install the wrong version.
