ESX vs QB-Core vs QBOX: Which FiveM Framework Should You Use in 2026?

Short answer: Choose ESX if you want the largest library of ready-made scripts and MLOs, QB-Core if you want a modern all-in-one roleplay feature set out of the box, and QBOX if you want QB-Core's features rebuilt for better performance and long-term maintenance. All three run the same MLOs — the framework mainly decides how your jobs, inventory and economy are wired.

What is a FiveM framework?

A framework is the backbone that turns GTA 5 into a roleplay server. It handles player data, jobs, money, inventory and the connective tissue between every script you install. Your MLOs (the interiors) sit on top of the framework — which is why a good marketplace ships MLOs that work across all three.

Factor	ESX	QB-Core	QBOX
Maturity	Oldest, most battle-tested	Established, very popular	Newest, actively maintained
Out-of-box features	Lean core, add scripts	Rich, roleplay-focused	Rich, QB-compatible

Script library	Largest	Very large	Growing, QB-compatible
Best for	Custom builds, max choice	Feature-complete RP fast	Performance + future-proofing

Which framework has the best performance?

QBOX generally has the performance edge in 2026 because it's a modern rewrite of QB-Core with cleaner code and better resource handling. That said, performance depends far more on how you configure your server than on the framework badge — an unoptimized ESX server and an unoptimized QBOX server will both lag. Optimized MLOs, sensible resource counts, and a good server host matter more than the framework name.

Which is easiest for beginners?

QB-Core is usually the friendliest starting point. It ships with a working inventory, jobs, and roleplay systems, so a new server owner can go from install to playable in an afternoon. ESX gives you more freedom but expects you to assemble more pieces yourself. QBOX feels familiar to anyone who has used QB-Core.

Do MLOs work across all three frameworks?

Yes. A well-built MLO is just a map interior — geometry, collisions and props. It doesn't care which framework runs your economy. The framework only comes into play when you attach jobs to the interior (for example, wiring a police station's armory to your police job). This is why quality marketplaces label MLOs as framework-ready for ESX, QB-Core and QBOX rather than framework-specific.

Which framework should you choose?

• Pick ESX if you plan heavy customization and want the widest pool of scripts and tutorials.
• Pick QB-Core if you want a complete roleplay experience with the least assembly.
• Pick QBOX if performance and long-term maintenance are your top priorities.

There's no universally "best" framework — only the best fit for your server's goals and your team's experience. Whichever you choose, your MLOs will drop in the same way.

The bottom line

The framework is the engine; MLOs are the world your players live in. Pick the framework that matches your team's skill and your performance goals, then fill your city with optimized, drop-in-ready interiors.
