Choosing a framework is the most important decision for a new FiveM server.

Overview

Side	ESX Legacy	QBCore	ox_core
Popularity	Very high (40%+)	High (35%+)	Growing (10%+)
Learning Curve	Low	Medium	High
Scripts Available	Most	More	Less but growing fast
Performance	good	good	best
Thai Community	very large	medium	small

ESX Legacy

Highlights

• The largest ecosystem — many scripts to choose from.
• Big Thai community — easy to find help
• M2Developer scripts support ESX as primary.

local xPlayer = ESX.GetPlayerFromId(source)
local money = xPlayer.getMoney()
xPlayer.addMoney(1000)
xPlayer.addInventoryItem('bread', 2)

QBCore

Highlights

• Modern design — newer pattern than ESX
• Better item system — metadata support

local Player = QBCore.Functions.GetPlayer(source)
Player.Functions.AddMoney('cash', 1000)
Player.Functions.AddItem('bread', 2, false, { freshness = 100 })

ox_core

Highlights

• Highest Performance
• Full TypeScript support
• ox_inventory, ox_lib ecosystem

import { Player } from '@overextended/ox_core/server';

onNet('myScript:buyItem', async () => {
    const player = Player(source);
    const balance = await player.get('money');
    if (balance < 1000) return;
    await player.set('money', balance - 1000);
    await player.addItem('bread', 2);
});

Selection advice

Choose ESX if: need a lot of scripts, Thai community, open server quickly

Choose QBCore if: Want a modern item system, balance between ecosystem and design

Choose ox_core if: want maximum performance, know TypeScript, long-term investment

Summary

For Thai servers, ESX Legacy is still the best choice because of the large community and M2Developer scripts that mainly support ESX.
