If you're setting up a FiveM GTA RP server, the most important decision you'll make is choosing your framework. The two dominant options in 2026 are QBCore and ESX (Extended). Your framework determines how your economy works, how jobs function, how inventory is managed, and ultimately how your server feels to play on.
This guide compares both frameworks across every important dimension to help you make the right choice.
Quick Comparison
| Feature | QBCore | ESX |
|---|---|---|
| Performance | Better (lighter) | Good (heavier) |
| Learning Curve | Moderate | Easier |
| Community Size | Larger (2026) | Large (mature) |
| Free Scripts | Abundant | Very abundant |
| Documentation | Good | Excellent |
| Active Development | Very active | Active |
| Best For | New servers, performance | Established servers |
What Is ESX?
ESX (Extended Survival) was the first major FiveM roleplay framework, launched in 2017. It pioneered many of the systems we now take for granted in RP servers: jobs, money, inventories, and player identities. For years, ESX was the framework — nearly every FiveM RP server ran on it.
ESX Strengths
- Massive script library: Thousands of ESX-compatible scripts have been created over 8+ years. You can find a pre-made script for almost anything
- Excellent documentation: Years of guides, tutorials, and forum posts make troubleshooting easy
- Familiar to players: Most RP players have played on ESX servers, so the UX patterns feel natural
- Easier to learn: ESX's structure is more straightforward for beginners
ESX Weaknesses
- Legacy code: Some core ESX code is older and less optimized
- Heavier resource usage: ESX tends to use more server resources than QBCore
- Fragmented versions: Multiple forks exist (ESX Legacy, ESX Infinity), which can cause confusion
What Is QBCore?
QBCore launched as a modern alternative to ESX, rebuilt from scratch with performance and security in mind. It gained massive popularity starting in 2022 and has become the dominant framework for new servers in 2026.
QBCore Strengths
- Better performance: QBCore was designed to be lightweight. Many benchmarks show 15-30% lower resource usage compared to equivalent ESX setups
- Modern codebase: Built with current Lua best practices and FiveM APIs
- Built-in security: Better anti-cheat integration and exploit prevention out of the box
- Active development: The QBCore team releases updates frequently with new features and fixes
- Growing community: The QBCore Discord has become one of the largest FiveM development communities
QBCore Weaknesses
- Steeper learning curve: QBCore's architecture is more complex for first-time developers
- Fewer legacy scripts: While growing fast, the QBCore script library is still smaller than ESX's
- Breaking changes: Active development means occasional updates that require script changes
Performance Comparison
Performance matters because it directly affects how many players your server can handle smoothly. Here's what we've observed on Azion Cloud game servers:
| Metric | QBCore | ESX Legacy |
|---|---|---|
| Idle server (no players) | ~0.8ms per tick | ~1.2ms per tick |
| 32 players | ~3.5ms per tick | ~5.0ms per tick |
| 64 players | ~6.5ms per tick | ~9.0ms per tick |
| RAM usage (base) | ~1.5 GB | ~2.0 GB |
QBCore consistently uses fewer resources, which means you can either run more players on the same hardware or spend less on hosting.
Which Framework Should You Choose?
Choose QBCore If:
- You're starting a new server from scratch
- Performance is a priority (64+ player servers)
- You want the most active development community
- You're comfortable with a moderate learning curve
- You plan to do custom development
Choose ESX If:
- You're migrating an existing server that already uses ESX
- You need specific scripts that are only available for ESX
- You're a beginner who wants the easiest setup
- You want maximum script compatibility without worrying about conversions
Can You Switch Between Frameworks?
Switching from ESX to QBCore (or vice versa) is possible but requires significant work. The frameworks use different database structures, different events, and different APIs. You'll need to:
- Convert or replace all scripts
- Migrate your database
- Retrain your development team
- Reset or migrate player data
For this reason, choosing the right framework before you launch is important.
Server Requirements
Regardless of framework, FiveM servers need strong hardware. Recommended specs for a 64-player server:
- CPU: High single-thread performance (3.5 GHz+)
- RAM: 8-16 GB depending on scripts
- Storage: 30-50 GB NVMe SSD
- Network: DDoS protection is essential for FiveM
Azion Cloud's FiveM hosting supports both QBCore and ESX with one-click installation through Pterodactyl. All plans include NVMe SSDs and DDoS protection. Check our FiveM server setup guide for step-by-step instructions.
