Framework Comparison
QBCore vs ESX Legacy
If you're spinning up a new FiveM roleplay server in 2026, the framework choice locks in almost every downstream decision — which scripts you can install, what your player onboarding feels like, and how much time you'll spend patching updates. QBCore and ESX are the two dominant options, and while they overlap heavily, the differences matter. This is a technical, no-marketing comparison based on actual production usage across both frameworks in 2026.
Verdict
For a brand-new server in 2026, QBCore is the safer bet — smaller cognitive load, modern statebag patterns, better long-term maintenance. ESX Legacy still wins if you're inheriting an existing player base or building a heavy legal-jobs economy where the vast script catalog outweighs framework modernity. If you're picking between them on merit alone, QBCore edges it.
Head-to-head breakdown
| Dimension | QBCore | ESX Legacy | A | B |
|---|---|---|---|---|
| Architecture | Modular resource system, per-resource config | Monolithic core, shared config | ✓ Better | – |
| Shared object bootstrap | `QBCore = exports['qb-core']:GetCoreObject()` | `ESX = nil; TriggerEvent('esx:getSharedObject')` | ✓ Better | – |
| Default inventory | `qb-inventory` (grid), auto-swaps to `ox_inventory` when present | `esx_inventoryhud` (grid), auto-swaps to `ox_inventory` | – | – |
| Menu system | `qb-menu`, `qb-input`, `ox_lib` | `esx_menu_default`, `esx_context`, `ox_lib` | – | – |
| Script ecosystem size | ~40% of active Tebex catalogue | ~55% of active Tebex catalogue | – | ✓ Better |
| New scripts (2025-2026) | Majority of new releases target QBCore first | New releases usually port after QBCore | ✓ Better | – |
| Whitelisted job / grade system | Boss menus + grades built into `qb-core` | Manual `TriggerServerCallback` pattern | ✓ Better | – |
| Statebag patterns | Modern statebag support out of the box | Retrofitted, some scripts still use events | ✓ Better | – |
| Cross-server migration | `qb-core` shared items table is portable | SQL exports work but per-server tuning | ✓ Better | – |
| Cfx.re escrow support | First-class in `qb-core` design docs | Supported but per-resource conventions | ✓ Better | – |
| Community docs | docs.qbcore.org — current, official | Documentation.esx-framework.com — dated | ✓ Better | – |
| Learning curve | Medium — modular can be confusing at first | Low — flat structure, easier to grep | – | ✓ Better |
| Idle resmon | ~0.02ms base (`qb-core`) | ~0.03ms base (`es_extended`) | ✓ Better | – |
| Player count scaling | Tested to 128+ players with minimal work | Tested to 96 players; 128 needs tuning | ✓ Better | – |
When to pick QBCore
Building a new server in 2026
QBCore is where new script development lives — 2025-2026 releases target it first, so your future script buying budget goes further.
You want boss menus + whitelisted jobs out of the box
The `qb-core` grade system + boss menus for police / EMS / mechanic are first-class. ESX gets you there, but you're writing the boss menu yourself.
You care about statebags + modern patterns
QBCore is architected around statebags for player state — that pattern is faster and more predictable than the ESX callback / event-based model.
Long-term maintainability
The modular resource system means updating one component (housing, inventory, jobs) doesn't require touching the core. Cleaner upgrade path.
When to pick ESX Legacy
You're inheriting an existing ESX server
Migrating live ESX data to QBCore is possible but non-trivial. If the server already runs ESX with an active playerbase, staying on ESX is usually the right call.
You need the biggest script catalogue right now
ESX still has ~55% of the active Tebex market by product count. If you need a very specific niche script and it only exists for ESX, that decides it.
Your team knows ESX inside out
Team knowledge beats theoretical framework merits. If your devs are ESX veterans, QBCore's learning curve is a real cost you're paying up front.
You want a flat, easy-to-grep codebase
ESX's monolithic structure is easier to explore end-to-end than QBCore's modular resources. Simpler mental model for solo devs.
QBCore vs ESX FAQ
Is QBCore better than ESX in 2026?+
For new servers, yes — QBCore is where new script development targets first, ships with modern statebag patterns, and has better long-term maintainability. ESX still wins if you're inheriting an existing playerbase or need its wider script catalogue.
Can I migrate my ESX server to QBCore?+
Yes, but it's a significant project — you're rewriting your inventory, jobs, and any custom scripts. Third-party migration tools exist (`esx-to-qbcore`) but expect at least 1-2 weeks of dev work even for a mid-size server.
Do QBCore and ESX use the same scripts?+
No. Scripts tagged `[QBCore/ESX]` support both via runtime detection. Pure-framework scripts don't cross-compile — they rely on framework-specific shared objects and event patterns.
Which framework has better performance?+
QBCore is slightly faster at idle (~0.02ms vs ~0.03ms base resmon) and scales more cleanly past 100 concurrent players. The difference is small in practice — script quality matters more than framework choice for perf.
Which framework is easier to learn?+
ESX is easier to explore end-to-end because it's flatter and monolithic. QBCore's modular structure has a steeper initial learning curve but pays off for teams maintaining a server long-term.
Which framework has more support scripts?+
ESX has ~55% of the active Tebex market; QBCore has ~40%; the remainder is Standalone / QBox. New releases in 2025-2026 target QBCore first, so the gap is closing.
