Running a successful FiveM server can be an expensive hobby. Between server hosting costs, Patreon subscriptions for clothing slots, and premium assets, the bills pile up quickly. But here is the secret that veteran server owners know: You don't need to pay for everything.
Some of the most powerful, optimized, and feature-rich scripts in the FiveM ecosystem are 100% free and open source. These aren't just "budget alternatives"; in many cases, they are the industry standard used by massive servers with thousands of players.
In this guide, we will break down the top 5 must-have open source scripts for 2025. These resources will stabilize your server, enhance roleplay, and save your budget for the things that truly need a premium touch—like custom cars and MLOs.
1. Ox Inventory: The Gold Standard of Item Management
If you are still using the default ESX menu inventory or an old "disc-inventory" leak, stop immediately. Ox Inventory has completely revolutionized how items are handled in FiveM.
Why It’s a Game Changer
Ox Inventory offers a sleek, drag-and-drop interface that feels like a modern RPG. But the real magic happens under the hood. It supports "metadata," meaning every item can have unique properties. A gun can have a specific serial number, a sandwich can decay over time, and a vehicle key can be tied to a specific plate.
- Compatibility: Works seamlessly with ESX, QBCore, and Qbox.
- Performance: Written in TypeScript/Lua, it is incredibly lightweight compared to older HTML inventories.
- Security: Built-in safeguards against item duplication (duping) exploits.
Pro Tip: Before installing, ensure you have Ox Lib and a compatible database resource like
oxmysqlinstalled. You can find compatible addons in our ESX Scripts category to pair with it.
2. pma-voice: Crystal Clear Communication
Voice chat is the lifeblood of roleplay. For years, servers struggled with external apps like TeamSpeak (TokoVoip). Today, pma-voice is the undisputed king of in-game audio.
High-Fidelity Audio
pma-voice acts as a wrapper for FiveM's built-in Mumble technology. It eliminates the need for players to install third-party plugins. It supports 3D audio, radio effects, and phone calls right out of the box.
- Grid System: It uses a smart grid system to sync voice only between nearby players, drastically reducing server lag.
- Radio Integration: It hooks perfectly into most phone and radio scripts.
Actionable Tip: To get the best audio quality, add setr voice_useNativeAudio true to your server.cfg. This enables GTA V's native audio filters, making radio chatter sound authentically static-filled and gritty.
3. NPWD (New Phone Who Dis): A Premium Phone for Free
For a long time, having a working smartphone in FiveM meant paying $50+ for a script like GKS or Quasar. Then came NPWD.
Standalone & Feature Rich
NPWD is a fully standalone, open-source phone built with React and TypeScript. It is smoother than most paid phones and looks incredibly professional.
- Apps: Comes with Twitter, Matchmaker (Tinder clone), Camera, Marketplace, and Messaging.
- Customization: Because it is open source, developers can build custom apps (like a specialized banking app) and load them into the phone easily.
Installation Warning: If you aren't a developer, do not download the "Source code" zip from GitHub. Look for the "Release" version on the right-hand sidebar. The release version is pre-built and ready to drag-and-drop into your resources folder.
4. Ox Target: The "Third Eye" Interaction
Modern servers have moved away from "Press E circles" on the ground. The standard now is the "Third Eye"—holding the Alt key to interact with the world. While there are many target scripts, Ox Target is the performance leader.
Performance First
Older target scripts (like qtarget or bt-target) often suffered from high CPU usage because they constantly checked for zones around the player. Ox Target is optimized to near-zero usage when idle.
- Versatility: You can make anything interactable—peds, vehicles, specific props (like ATMs), or abstract zones.
- Backwards Compatibility: It is designed to work with most scripts that were built for qtarget, making the switch easy.
Enhance your world: Use Ox Target to interact with our custom MLO interiors. Imagine walking up to a custom coffee machine and third-eyeing it to brew a cup!
5. Ox Lib: The Unsung Hero
While not a "gameplay" script itself, Ox Lib deserves a spot on this list because it powers almost every modern open-source resource.
The Developer's Toolkit
Ox Lib is a collection of optimized functions that handle everything from progress bars and context menus to database queries and math.
- Why you need it: If you download a modern script in 2025, there is a 90% chance it requires Ox Lib.
- The Interface: It provides a beautiful, unified look for your menus and input dialogs, ensuring your server doesn't look like a patchwork of different styles.
Setup Tip: Always start ensure ox_lib at the very top of your server.cfg, right after your database script. It needs to load before everything else.
Summary: Building Smart, Not Expensive
You don't need a limitless budget to build a "NoPixel-like" server. By utilizing these powerful open-source tools—Ox Inventory, pma-voice, NPWD, Ox Target, and Ox Lib—you build a rock-solid foundation that is secure, optimized, and free.
This allows you to allocate your budget where it matters most: Visuals. Use your savings to invest in high-quality assets that players can actually see, like custom uniforms and unique vehicles.
