QBCore vs ESX: which framework should you pick for a new role-play server?

If you are starting a new FiveM role-play server in 2026, you will almost certainly end up choosing between QBCore and ESX. Both are mature, free, open-source frameworks with thousands of community scripts. Both will get you to a playable server in a weekend. But they make very different trade-offs, and picking the wrong one for your team can cost you weeks of refactoring later.

Architecture

ESX is older. It was designed in the early days of FiveM when servers were simpler, and its codebase reflects that — a lot of global state, tight coupling between core and jobs, and a permissive event model. ESX Legacy (the actively maintained fork) has cleaned a lot of this up but the legacy patterns still show.

QBCore was built with hindsight. It uses metatables, exports for almost everything, has a clear separation between client and server logic, and ships with a modern oxmysql integration out of the box. New developers tend to find QBCore code easier to read.

Performance

On an empty server both frameworks idle at well under 0.1 ms server tick. The real difference shows up at 64+ players: QBCore generally edges out ESX by 15–20% on server-side tick because of more aggressive caching and fewer global event broadcasts. That said, your custom scripts will dwarf the framework cost in either case.

Available scripts

ESX has the larger ecosystem by sheer volume — almost a decade of community scripts exist for it. But many are unmaintained or written for ESX Legacy 1.1 and need patching. QBCore has fewer scripts overall but a much higher proportion of them are actively maintained and written in the last two years.

Learning curve

If your team has never written a FiveM resource before, QBCore is friendlier. The official documentation is more complete, the export pattern is consistent, and the Discord community is faster at answering beginner questions. ESX has more YouTube tutorials but many are outdated.

Long-term maintenance

Both frameworks are maintained by volunteers. QBCore has a more centralised core team, which means changes are more consistent but also slower. ESX is more federated — multiple forks (Legacy, ox_core-compatible builds) coexist, which gives you flexibility but makes upgrading painful.

Our recommendation

For a brand-new role-play server with a small team in 2026, pick QBCore. It is easier to learn, performs slightly better at scale and has a healthier modern script ecosystem.

Pick ESX Legacy only if (a) your team already has years of ESX experience, (b) you specifically need a script that exists only on ESX, or (c) you want maximum flexibility and are comfortable maintaining your own fork.

Whichever you pick, commit to it for at least six months before considering a migration. Switching frameworks mid-flight is one of the most common reasons new servers die.
