How to make a Roblox game with AI, free for beginners

Short answer: install Roblox Studio (free), open a Baseplate, and ask the built-in Assistant to plan and build a simple obby. Then playtest it, tell Assistant what is broken, and polish. If you already use an AI coding agent like Claude Code, Codex or Cursor, you can connect it to Studio's built-in MCP server instead. Everything below comes from Roblox's own docs and announcements, checked October 2026.

What you need

• A computer. Roblox Studio runs on Windows 10 or newer and macOS 10.14 or newer. Roblox lists 3 GB of RAM as the minimum and 8 GB as recommended.
• A free Roblox account. You sign in to Studio with it.
• A tiny idea. Roblox's own AI guide suggests an obby (an obstacle course) as a great first project. We agree.

You do not need to know how to code. Roblox games are scripted in Luau, a language derived from Lua 5.1, but AI can write most of it for you while you learn.

The tools

What Roblox's built-in AI can do now

Roblox has a lot of official AI tools built in. Here is what its docs describe as of October 2026.

• Assistant. A chat helper inside Studio. It answers questions about Roblox development, creates and edits objects and scripts in your game, explains code, inserts free or paid assets from the Creator Store, and can start a playtest and simulate player input to check its own work. It can also look at your 3D view and tell you what it sees.
• Planning Mode. Pick Plan in the Assistant dropdown, or type /plan. Assistant writes a step by step plan you can edit. Nothing runs until you click Build.
• Mesh generation. Type /generate_mesh and a description, like a red buggy with knobby tires, or give it a reference image. You get a textured 3D model. Roblox's newsroom says this is powered by its Cube 3D model, and an open source version of Cube 3D is on GitHub and Hugging Face.
• Procedural models. /generate_procedural_model makes objects built from simple parts that you can resize and tweak later. Roblox caps this at 50 in a rolling 24 hours.
• Materials and textures. /generate_material restyles parts with a new surface, like weathered stone. /generate_texture paints a texture onto a mesh. On October 16, 2026 Roblox added a Quality mode in beta that makes 4K textures in about 2 minutes. The Fast mode makes 1K textures in about 30 seconds.
• Code Assist. Suggests the next lines of code as you type in the Script Editor. Press Tab to accept. Roblox warns the suggestions are not always right, so test them.
• Built-in MCP server. Lets outside AI agents work inside your open Studio session. More on this below.

What about price? Studio is free. Roblox's Assistant guide does not list a price for Assistant (checked October 2026). The one usage cap it spells out is 50 procedural models in a rolling 24 hours. If you want to pick the AI model yourself, you can add your own API key from Anthropic, OpenAI or Google under Assistant settings, then Manage API Keys. You pay that company for what you use.

Also new: Build on phones. Roblox is rolling out Build, a tab in the Roblox mobile app that makes simple 2D and 2.5D games from a description. Roblox says it is rolling out gradually, starting with New Zealand, and playtesting inside Build is marked as coming soon. You get some free prompts each day and can buy more with Robux. If you later open a Build game in Studio, it permanently becomes a normal Studio game.

Your first Roblox game in an afternoon

This follows the Plan, Build and Playtest, Refine and Polish loop from Roblox's own beginner guide. Your results will look different from ours, because Assistant's answers change each time. That is normal.

1. Install Studio. Download it from Roblox's Creator Hub, install it, and sign in with your Roblox account.
2. Start a Baseplate. Create a new Baseplate, then click Assistant near the top right of Studio to open the Assistant window.
3. Plan it. Switch the dropdown to Plan and try Roblox's example prompt: Plan a simple obby where players jump through increasingly difficult obstacle courses to reach the end. Include checkpoints so they don't restart from the beginning when they fall. Read the plan. If it looks too big, ask Assistant to make it smaller.
4. Build it. Click Build. If you see a message that the response exceeded the maximum output length, click Continue and it picks up where it left off.
5. Playtest it. Press Play and run the whole course. Can you make every jump? Do checkpoints save your spot? Does the end say you won?
6. Fix it in plain English. Tell Assistant what you expected and what actually happened, like When I touch a checkpoint, nothing happens. If the Output window shows a red error, paste it in and ask what it means. Playtest again after each fix.
7. Make it pretty. Try /generate_mesh a stone archway for the start, or /generate_material for a cool winning platform. Then nudge things by hand with the Move, Scale and Rotate tools. Small tweaks are faster by hand than by prompt.
8. Publish it. Use File, then Publish. A new game starts out playable only by you and people you invite. Roblox is rolling out early tester invites for up to 10 friends. To go public for players 16 and up, Roblox requires an account in good standing that is at least 2 days old, an age check, and one question about age-restricted content. Reaching younger players takes more steps, like ID or face age verification, 2FA, and a content review.

Curious what Luau looks like? This is a classic kill brick. Put it in a Script inside a part, and any player who touches the part is knocked out and respawns. Assistant writes code like this for you, and asking it to explain each line is a great way to learn.

local part = script.Parent

part.Touched:Connect(function(hit)
  local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")
  if humanoid then
    humanoid.Health = 0
  end
end)

Using ChatGPT, Claude, Codex or Cursor with Roblox

You do not have to use Assistant. There are three ways to bring the AI you already use.

1. Copy and paste (easiest)

Ask a chat assistant like ChatGPT or Claude for a Luau script, then paste it into a Script in Studio. Tell it the script is for Roblox, and say where the script goes, like inside a part or in ServerScriptService. Paste any errors back in.

2. Connect an agent to Studio's MCP server

Studio has a built-in MCP server. MCP (Model Context Protocol) is a standard way to let an AI agent use tools in another app. Once connected, your agent can read and edit scripts, run Luau, explore your game, start and stop playtests, read the Output log, take screenshots of the viewport, and even generate meshes.

1. Install your agent first, for example Claude Code, Codex CLI or Cursor.
2. In Studio, open Assistant, click the ... menu, then Manage MCP Servers, and turn on Enable Studio as MCP server.
3. Under Quick connect, flip the toggle for your agent. Roblox lists Antigravity, Codex CLI, Claude Code, Claude Desktop, Cursor, Gemini CLI and Visual Studio Code. Other agents can connect with a short config file instead.
4. Restart your agent. A green dot in Studio shows it is connected.

Roblox's warning is worth repeating: a connected agent can read and change your open places, so only connect tools you trust.

3. Work on script files on your computer

If you want your agent or editor to work on real files, Roblox offers Script Sync. It mirrors your scripts to .luau files on your disk, so edits in Cursor or VS Code show up in Studio right away, and the other way too. Roblox's coding harness guide has you turn it on under File, then Beta Features. Pair it with the MCP server for anything that is not a script, like UI.

Want your whole project as files, not just scripts? Rojo is a popular community tool that syncs files on your computer with Studio through a plugin. Roblox's docs explain how to set it up, but note that Rojo is not maintained by Roblox. For a first game, Script Sync is simpler.

Can you make money?

Maybe, but treat your first game as practice. Roblox lets you sell things for Robux, like passes (a one time purchase, such as a permanent power-up) and developer products (things players can buy more than once). Your game has to be published first. To turn Earned Robux into real money through the Developer Exchange (DevEx), Roblox requires you to be at least 13, have at least 30,000 Earned Robux, a verified email and tax forms, among other rules. The standard rate is $114 USD for 30,000 Earned Robux.

Tips that save time

• Start smaller than you think. One obby with five stages beats a half finished open world.
• Playtest after every change. Small changes can break things in surprising ways.
• Fix one thing at a time. Gameplay first, then looks, then UI and sound.
• Read what the AI wrote. Ask it to explain scripts in simple words. You will learn Luau without trying.
