QBCore Framework on FiveM, Compatibility, APIs, and FiveM Coach by Quasar Coverage

What it is

QBCore was built around 2021 as a more opinionated, more modern alternative to ESX. It standardized around oxmysql for database access (rather than the older mysql-async), introduced a cleaner Player object pattern via QBCore.Functions, and shipped a coherent set of qb-* resources (qb-inventory, qb-menu, qb-target, qb-policejob, qb-banking) so a new server could be operational with minimal external dependencies.

Server-side, you typically grab the framework with QBCore = exports['qb-core']:GetCoreObject(), then access players with QBCore.Functions.GetPlayer(source). Player methods follow a verb-driven API (Functions.AddMoney, Functions.AddItem, Functions.SetMetaData) and metadata is a first-class concept rather than the bolted-on pattern it became in ESX.

QBCore's growth from 2022 onward made it the default target for a large generation of scripts, anything labeled "qb-" or "qb compatible" assumes the QBCore environment. A meaningful subset of new servers from 2023 onward pick QBCore over ESX as their starting point.

When to choose QBCore

• You want a more opinionated, more cohesive default resource set than ESX provides out of the box.
• Your team prefers verb-driven, namespaced APIs (Functions.AddMoney) over ESX's xPlayer.addMoney style.
• You're starting a new server in 2025-2026 and want a modern, well-maintained baseline without the QBox migration learning curve.
• You want metadata-driven design (player metadata, item metadata) as a first-class concept rather than a community pattern bolted on top.

Version timeline

Signature code patterns

local Player = QBCore.Functions.GetPlayer(source)
if Player then
  Player.Functions.AddMoney('cash', 500, 'gift-from-admin')
  TriggerClientEvent('QBCore:Notify', source, 'You received $500', 'success')
end

QBCore.Functions.CreateCallback('myresource:hasItem', function(source, cb, itemName)
  local Player = QBCore.Functions.GetPlayer(source)
  local item = Player.Functions.GetItemByName(itemName)
  cb(item ~= nil and item.amount > 0)
end)

Common pitfalls

Common questions about QBCore

Is QBCore better than ESX?

Better is the wrong frame. QBCore is more opinionated and more cohesive out of the box; ESX has the larger ecosystem of compatible scripts. Pick by ecosystem fit and team familiarity, not by which is "newer."

Should I migrate from QBCore to QBox?

Qbox is the actively developed QBCore successor, built on the ox stack (ox_lib and oxmysql are hard dependencies; ox_inventory is the default, officially supported inventory). Its built-in qb-core bridge runs most QBCore scripts unmodified, so migration is usually low-effort. Move if you want active development and the ox ecosystem; stay on QBCore if its larger ready-made catalog matters more. See /compatibility/qbcore-vs-qbox.

Does FiveM Coach by Quasar ship QBCore-specific milestones?

Yes. Developer-path students can pick QBCore as their primary framework during onboarding, and milestone projects are scoped to the QBCore Player object and qb-* resource patterns.

Can I run qb-* scripts under ESX?

Not directly — running a qb-* script under ESX means rewriting it against the ESX API. There is no drop-in layer that runs unmodified qb scripts on ESX. (Multi-framework bridge libraries like community_bridge, bl_bridge, or jim_bridge exist, but those are abstraction APIs you write a new script against, not a compatibility shim for existing qb scripts.) Note this is the opposite of Qbox, which ships a built-in qb-core bridge so most QBCore scripts run on Qbox unmodified.

Is QBCore still being updated in 2026?

Yes, QBCore still receives ongoing maintenance (commits through mid-2026), but its development pace has slowed and most new-feature momentum has moved to Qbox, the actively developed QBCore-compatible successor. QBCore remains a viable production choice with a large ecosystem; Qbox is the common recommendation for new 2026 builds.
