Best FiveM Inventory Systems Compared: Which One Should You Use?

The inventory system is one of the most-used interfaces in any FiveM RP server. Players interact with it constantly — picking up items, using consumables, equipping weapons, trading with other players, storing things in vehicles and stashes. A sluggish, buggy, or confusing inventory can single-handedly ruin the player experience.

In this guide, we'll compare the most popular FiveM inventory systems, break down their features, performance characteristics, and framework compatibility, and help you choose the right one for your server.

What Makes a Good Inventory System?

Before comparing specific scripts, let's define what "good" means for an inventory:

• Responsive UI: Drag-and-drop should be instant. No lag when opening, moving items, or closing
• Visual clarity: Items should be easy to identify with clear icons, names, weights, and quantities
• Weight/slot system: A balanced limitation system — either weight-based, slot-based, or both
• Stash support: Personal stashes, shared stashes, vehicle trunks, glovebox, property storage
• Weapon attachments: Ability to add/remove scopes, suppressors, flashlights, extended mags
• Hotbar: Quick-access slots for frequently used items (1-5 keys)
• Crafting integration: Works seamlessly with crafting systems
• Shop support: Built-in or compatible with shop/store scripts
• Drop system: Drop items in the world as pickable objects
• Decay system: Items degrade over time (food expires, weapons wear down)
• Performance: Low resource usage — inventory code runs constantly and affects every player

The Top Inventory Systems

1. ox_inventory (Overextended)

Framework: ESX, QBCore, QBox, Standalone
License: Open-source (LGPL)
UI: React-based NUI

ox_inventory has become the community standard for many reasons. Built by the Overextended team, it's framework-agnostic, performant, and feature-rich. It uses a slot + weight hybrid system where each slot has a weight capacity.

Key features:

• Drag-and-drop with smooth animations
• Real-time search and filtering
• Custom context menus per item
• Built-in shop system with configurable prices
• Weapon attachments and durability
• Evidence and police search integration
• Stash, trunk, glovebox, drop support
• Item decay/expiry system
• Crafting system built-in
• Metadata system for unique item properties (serial numbers, descriptions)

Pros:

• Best performance of any major inventory (Rust-based item comparison)
• Most feature-complete out of the box
• Excellent documentation and active community
• Works with any framework via bridge system
• Actively maintained and regularly updated

Cons:

• Setup can be complex for beginners (requires ox_lib, oxmysql)
• Opinionated design — some customization requires forking the source
• Migration from other inventories requires item data conversion

Verdict: If you're starting a new server or willing to migrate, ox_inventory is the recommended choice for most setups. Its performance, features, and community support are unmatched.

2. qb-inventory (QBCore Default)

Framework: QBCore
License: Open-source
UI: HTML/CSS/jQuery

The default inventory that ships with QBCore. It's functional but basic compared to alternatives. Many QBCore servers replace it with ox_inventory or a premium alternative.

Key features:

• Slot-based system (5 per row, configurable slots)
• Drag-and-drop item movement
• Vehicle trunk and glovebox
• Drop items on the ground
• Hotbar (1-5 slots)
• Basic weapon attachment support

Pros:

• Plug-and-play with QBCore — no extra setup
• Simple codebase — easy to understand and modify
• Most QBCore scripts are built to work with it

Cons:

• jQuery-based UI is sluggish with many items
• No built-in item decay or metadata
• Limited stash system
• No search/filter functionality
• Dated UI design

3. qs-inventory (Quasar Store)

Framework: QBCore, ESX
License: Premium (paid)
UI: React/Vue-based NUI

A premium alternative with a polished, modern UI. Popular among servers that want a visual upgrade without the complexity of ox_inventory migration.

Key features:

• Modern, sleek UI with smooth animations
• Weight + slot hybrid system
• Built-in crafting interface
• Weapon wheel integration
• Item splitting and stacking
• Custom item descriptions and images

Pros:

• Beautiful UI out of the box
• Easy installation for QBCore/ESX
• Regular updates and support

Cons:

• Paid — ongoing cost for updates
• Closed source — can't modify core logic
• Not as performant as ox_inventory in stress tests

4. core_inventory (Custom/Framework-specific)

Framework: Various
License: Varies

Some servers build or commission fully custom inventory systems tailored to their specific RP vision. This is common among large servers with unique mechanics.

Pros:

• Exactly fits your server's needs
• No compatibility issues
• Unique — differentiates your server

Cons:

• Expensive to develop
• Maintenance burden — you're responsible for bugs and updates
• Third-party scripts may not be compatible

Feature Comparison Table

Migrating Between Inventory Systems

Switching inventory systems mid-server is one of the most painful operations you can do. Here's what's involved:

Data Migration

Different inventories store data in different formats. You'll need to:

1. Export existing data: Dump all player inventories, stashes, and trunk contents from your current database tables
2. Transform the format: Convert item names, metadata, slot positions, and quantities to the new inventory's schema
3. Import to new tables: Load the transformed data into the new inventory's database
4. Verify integrity: Check that no items were lost or duplicated in the process

Warning: Always do inventory migrations on a test server first. A botched migration can delete every player's items — and that's a server-ending event. Make multiple backups before starting.

Script Compatibility

This is the bigger issue. Every script that interacts with the inventory (shops, crafting, jobs, drug systems, housing, vehicles) uses inventory-specific exports and events. When you switch inventories, you need to update every single one of these scripts to use the new API.

Common functions that change between inventories:

-- qb-inventory
exports['qb-inventory']:AddItem(source, 'item_name', 1)
exports['qb-inventory']:RemoveItem(source, 'item_name', 1)

-- ox_inventory
exports.ox_inventory:AddItem(source, 'item_name', 1)
exports.ox_inventory:RemoveItem(source, 'item_name', 1)

-- The function names look similar but the internals,
-- metadata handling, and return values differ significantly

Optimizing Your Inventory

Regardless of which system you choose, follow these performance tips:

• Limit item images: Each item icon is loaded into the NUI browser. Use compressed PNG or WebP images under 10KB each
• Database indexing: Ensure inventory tables have proper indexes on owner and identifier columns
• Save intervals: Don't save to database on every item movement. Batch saves every 30-60 seconds
• Stash cleanup: Periodically clear empty or abandoned stashes from the database
• Item count limits: Set maximum stack sizes and total item counts to prevent database bloat

Your inventory system is the most interacted-with script on your server. Choose wisely, invest time in configuration, and your players will have a smoother experience for it. Check out our store for scripts that integrate seamlessly with all major inventory systems.
