How to choose an AI tool for FiveM

Guide · checked against the docs on Oct 15, 2026

There isn't one right AI tool for FiveM, and this page won't pretend there is. What suits you depends on how you work, what you can spend, and how much of your server code you're willing to send to someone else's computer. What we can give you is a short list of things to check, and a small test you can run yourself in an evening.

The kinds of tool you'll be choosing between

Most AI coding tools fall into a few groups. We keep a hand-checked list for each:

• AI coding assistants sit inside your editor and suggest code as you type, with a chat panel on the side.
• AI code editors are whole editors built around AI, so they can read and change many files at once.
• AI coding agents take a task, edit the files and often run commands for you, in the terminal or the cloud.
• Code review tools read a change after it's written and point out problems.

A plain chat window counts too. For a small FiveM resource, pasting three files into a chat works fine. It just gets tiring once your server has forty resources.

1. Does it see your whole resource?

FiveM bugs often live between files: the client fires myres:buy, but the server registered myres:purchase. A tool that only sees the file you have open can't spot that.

Check:

• Can it read the whole resource folder, including fxmanifest.lua, or only what you paste in?
• Can you point it at a single resource instead of your entire resources folder? Smaller context usually means fewer wrong guesses, and on metered plans it costs less.
• Does it pick up a rules file? Many tools read a project instructions file (names vary by tool). Put your house rules in it once, such as "standalone Lua, no framework, the server decides", instead of repeating them in every prompt.

2. Can it run and lint code on your PC?

AI tools write Lua that looks fine and doesn't load. The fastest fix is a tool that can run luacheck itself, read the warnings and try again.

Check:

• Can it run terminal commands, with your approval?
• Can it run a small offline test that fakes the FiveM functions? This doesn't need a game server. Our FiveM script guide shows the idea.
• Does it ask before it runs a command? You want it to. An agent that can run anything can also delete anything.

Remember that a clean lint only proves the syntax and names are fine. It says nothing about security.

3. Does it stick to the Cfx docs?

This is a common place AI tools go wrong with FiveM. They invent natives with plausible names, use GTA natives on the wrong side (client vs server), or add manifest lines that are out of date. lua54 'yes' is a good tell: the manifest reference marks it deprecated, because all Lua scripts have run on 5.4 since June 2025.

Check:

• Can it read a web page or a pasted doc, so you can hand it the natives reference page for the function in question?
• When you ask "which natives did you use, and is each one client or server?", does it answer clearly, or does it wave the question away?
• Does it mix frameworks? Name one framework (or "none") in every prompt and see whether it listens.

4. Does it check on the server without being told?

This matters more than anything else on the list. In FiveM, any client can fire any server event with any values. A script that trusts the client is how servers get abused.

Watch whether the tool, unprompted:

• uses source for the player instead of a player ID sent by the client
• checks the type of every argument
• checks values against a list the server owns
• adds a per-player cooldown
• cleans up per-player data on playerDropped

Putting these rules in the prompt helps. What you're testing is how much the tool does on its own, because one day you'll forget to ask.

5. What does it cost, and is there a free tier?

Plans change all the time, so treat this as a snapshot. These figures come from each vendor's own pricing page, read on October 15, 2026, and are listed alphabetically. They aren't a recommendation.

What to look for:

• Free tiers are for trying, not for building a server. They run out fast once an agent starts reading files.
• "Bring your own key" tools cost nothing up front, but you pay your model provider per use. Set a spending limit with the provider before you start.
• Usage-based plans charge by how much the tool reads and writes, so a huge context costs more. Pointing the tool at one resource helps here too.
• Prices above don't include tax.

6. Where does your server code go?

Paid scripts, anti-cheat logic and your own server's secrets are worth protecting. Before you paste them anywhere:

• Is your code used for training? Read the plan's data settings. GitHub's Copilot plans page, for example, says Free, Pro and Pro+ interactions may be used for training unless you opt out in settings, and Business and Enterprise data isn't. Cursor says that with Privacy Mode on, code isn't used for training. Claude's plans list model training as opt-out on Free, Pro and Max. Settings like these change, so check yours.
• Can it run on a local model? Some tools, such as Aider, can connect to local models, so the code never leaves your PC. Local models are usually weaker, so test them on real tasks.
• Never paste secrets. Keep your license key, database passwords, webhook URLs and Tebex secrets out of any prompt. Keep them in server.cfg or convars, and leave that file out of what the tool can read.
• Escrowed or bought resources may have license terms that forbid sharing the code. Read them first.

Test it yourself: the /team check

Don't take anyone's word for which tool is good, including ours. Give each tool you're considering the same small job and score what comes back. We use the /team resource from our FiveM script guide. Here is the job:

Write a standalone FiveM resource in Lua (no framework).
/team <red|blue|green> puts the player on a team. /myteam shows their team.
Give me fxmanifest.lua, client.lua and server.lua, and list every native you used.

That prompt doesn't mention security on purpose. Then score the result:

• [ ] fxmanifest.lua has fx_version 'cerulean' and game 'gta5', and no lua54 'yes'
• [ ] Every native it lists exists in the natives reference and runs on the side it's used on
• [ ] The server uses source, saved to a local first, and never takes a player ID from the client
• [ ] The server checks that the team is a string and on a fixed list
• [ ] There's a cooldown on the server event
• [ ] playerDropped clears the player's data
• [ ] luacheck passes, or the tool fixes it when you paste the warnings back
• [ ] When you ask "how could a cheater abuse this?", it finds its own holes and fixes them
• [ ] You know where the code you sent went, and whether it can be used for training

Run the same prompt on each tool, in a fresh chat, and keep the answers. Score the code, not how confident the tool sounds. Then decide whether the price and the privacy terms work for you. (This checklist is a method, not a result. We haven't published scores for any tool.)

Next step

• Build the /team resource yourself with our FiveM script guide.
• The FiveM Server Pack (coming soon) is a set of prompts built around the same "the server decides" rules.
• New to FiveM? Our beginner guide isn't on the site yet. Until it is, start from the RedM and FiveM prompts hub.
