Starting a FiveM roleplay server in 2026 means picking a framework first — and the real question isn’t QBCore vs ESX anymore, it’s QBCore vs Qbox. We’ve shipped scripts for both and migrated servers between them. Here’s the honest comparison.
The Short Version
Pick Qbox for a new server. It’s the actively-maintained fork of QBCore, built on the modern ox ecosystem, with stricter security and better performance patterns. Pick QBCore only if you’re buying into an existing server or a script library that hasn’t been bridged yet — and even then, most QBCore scripts run on Qbox through its compatibility bridge.
What’s Actually Different
Maintenance and momentum
QBCore’s original team largely moved on; updates slowed dramatically. Qbox forked it, kept the data model, and ships regular updates. When a FiveM artifact change breaks something, Qbox patches in days.
The ox ecosystem
Qbox is designed around ox_lib, ox_inventory, and oxmysql — the de-facto standard libraries for UI, inventory, and database access. QBCore predates them and carries older patterns (qb-menu, qb-inventory) that most script developers have abandoned.
Security
Qbox pushes validation server-side by default and its exports make it harder to write exploitable resources by accident. QBCore’s looser patterns are a big reason “money exploit” is a support ticket genre.
Script compatibility
This is the part that surprises people: most QBCore scripts just work on Qbox. The player data layout differs in places (metadata access, job structure), so badly-written resources need small patches — but the bridge covers the common paths. Every script in our store is built and tested on Qbox and QBCore both.
Migration: Harder Than Installing, Easier Than You Fear
Moving an existing QBCore city to Qbox is mostly about your third-party resources, not the core — the database carries over with minor schema updates. The pain points are old scripts that reach into player data directly. We do these migrations as part of custom work; a typical city takes one to two weeks including testing.
What About ESX?
ESX is still huge in the European scene and perfectly viable — but if you’re choosing fresh in the US market, the script selection, developer pool, and momentum are on the qb-family side. We build for Qbox first for a reason.
