What is it?

Your all-in-one FiveM development companion—rebuilt from the ground up.

DevMate v2 brings debugging, resource management, live inspection, and server development tools together in one streamlined interface. Work directly in game or use the optional DevMate Desktop companion for a larger workspace and live FiveM client logs.

Built by Whitigol and TheLaw, DevMate is distributed and fully supported by Big Daddy Scripts.

Features

Completely Rebuilt Interface

DevMate v2 introduces a redesigned interface that keeps every development tool organized and easy to access.

Unauthorized modules remain visible with clear permission indicators, while every action continues to be validated by the server.

DevMate Desktop

The optional Windows Desktop companion brings your authorized DevMate tools outside the game.

• Connects automatically to FiveM on the same computer
• Requires no pairing code or account sign-in
• Mirrors the permissions granted to your current player
• Provides a larger workspace for development
• Includes automatic Desktop updates
• Uses a local-only connection between FiveM and the Desktop app

Client Logs

Monitor the live FiveM client console from DevMate Desktop.

• Search console output
• Filter information, success, warning, and error messages
• Copy output
• Open the active log file or FiveM logs folder
• Send commands to the FiveM client console
• Automatically reconnect when FiveM restarts

Safe Restart

Safely stop or restart resources while reducing the risk of leftover entities and client instability.

DevMate warns connected clients, allows the target resource to clean up spawned entities, waits for the configured delay, and then completes the requested operation.

Entity Viewer

Inspect and debug nearby game entities in real time.

• View nearby objects
• View nearby vehicles
• View nearby pedestrians
• Display entity bounds and details
• Use Free Aim to inspect, freeze, or delete a targeted entity

Resource Manager

Manage server resources from the DevMate interface.

• Search installed resources
• View live resource states
• Start stopped resources
• Safely restart running resources
• Stop resources
• Confirm destructive actions before they are sent

Resource Explorer

Browse and edit server resource files without leaving DevMate.

• Navigate resource directories
• Open and edit supported text files
• Save changes directly to the server
• Start, stop, or restart the selected resource
• Restrict access through dedicated permissions
• Reject unsafe paths, binary files, and oversized files

Resource Explorer uses explicit FiveM filesystem permissions generated for each discovered resource. Newly discovered resources remain pending until the next full server restart.

Warning: Resource Explorer can expose configuration files, source code, and secrets stored inside server resources. Grant access only to trusted developers.

Code Executor

Run code directly in the client or server runtime for rapid testing and debugging.

Supported languages:

• Lua
• JavaScript

Supported runtimes:

• Client
• Server

Execution results and runtime errors are returned directly to the interface.

Warning: Code Executor provides arbitrary code execution. Server-side code can access data, call exports, run commands, and disrupt the server. Grant this feature only to fully trusted developers.

Event Watcher

Subscribe to specific client or server events and inspect their payloads as they occur.

• Watch client events
• Watch server events
• View captured payloads and timestamps
• Manage active subscriptions
• Retain the latest 200 captured events
• Clear captured events from the interface

Internal DevMate events are protected from monitoring.

Warning: Captured event payloads may contain player identifiers or other sensitive information. Review all captured data before sharing it.

OneSync Blip

Display an approximate OneSync radius around your player.

The radius follows the player while enabled, making synchronization boundaries easier to visualize during testing.

Game Modifier

Adjust pedestrian and vehicle traffic density from 0% to 100%.

This is useful for performance testing, repeatable development environments, and testing gameplay under different population conditions.

Coordinates Tool

View, measure, and copy player coordinates in developer-friendly formats.

• Live X, Y, and Z coordinates
• Current heading
• Detected or estimated ground Z
• Distance measurement from a saved origin
• Copy as JSON
• Copy as JavaScript
• Copy as C#
• Copy as Lua vector4

Bone Viewer

Search and display supported vehicle and pedestrian bones in game.

• Search hundreds of available bones
• Separate vehicle and pedestrian bone data
• Enable multiple bones at once
• Track the number of active selections

Permission System

DevMate uses configurable FiveM ACE permission groups to protect every module.

Create different access levels for administrators, developers, testers, or any custom group used by your server. Sensitive actions are enforced by the server, including actions sent through DevMate Desktop.

Dedicated permissions are available for:

• Opening DevMate
• Entity Viewer
• Resource Manager
• Resource Explorer
• Code Executor
• Event Watcher
• OneSync Blip
• Game Modifier
• Coordinates Tool
• Bone Viewer

Automatic Updates

DevMate can automatically download and verify resource updates during server startup.

• Preserves protected configuration and permission files
• Migrates supported older configurations to the v2 format
• Continues running the installed version if an update fails
• Clearly reports when a restart is required to load an update

Requirements

• A valid DevMate license
• A FiveM server
• Access to the server files and server.cfg
• Experience configuring FiveM resources and ACE permissions
• Windows for the optional DevMate Desktop application

Hosting Compatibility Notice

Some game-server hosting providers restrict resources, server commands, filesystem access, or outbound connections.

DevMate may not function correctly on hosting platforms that block these features. Confirm compatibility with your hosting provider before purchasing.

Purchasing without confirming that your server environment and experience level meet these requirements does not qualify the purchase for a refund.
