Comparison
The best AI for Roblox Studio, honestly compared
The short answer
There is no single best one. Start with Roblox Assistant: it is built into Studio and Roblox's docs list no price for it. Add an MCP client such as Claude Code, or a Studio agent, for another workflow or price. Pick RoCode for 1 free credit a day and an agent that builds in your open place through its own plugin. It does not use Roblox's built-in Studio MCP server. For a simple 2D game on a phone, Roblox's own Build tab in the mobile app has free prompts every day, where it has rolled out.

At a glance
Roblox AI tools side by side
Feature lists are not what separates these tools. Where they run is: inside the place you have open, in a browser, or in a chat tab. Checked against each maker's own docs or site between 30 September and 23 October 2026. Each tool has its own section below, with what it is best for.
| Option | Works in your open place | Setup | Free option | Notable limits |
|---|---|---|---|---|
| Roblox Assistant (built in) |
Yes. Edits scripts and objects, runs Luau, playtests, inserts Creator Store assets, generates meshes. | None. Click Assistant in Studio. | Comes with Studio, and its docs list no price. | The one cap its docs state: 50 procedural models per rolling 24 hours. |
| Studio MCP server with your AI client |
Yes. Edits scripts, runs Luau, starts playtests, simulates input. | Turn on Studio's MCP server, then connect Claude Code, Cursor or Codex CLI. | The server comes with Studio. The client has its own price. | You install and connect the client yourself. It can run code in your session. |
| BloxBot (free desktop app) |
Yes, through Studio's built-in MCP server, which it connects to your own model. No plugin. | Install the app (Windows, macOS or Linux), turn on Studio's MCP server, then sign in with ChatGPT Plus or Pro, add an API key or pick a local model. | Free and open source (MIT). | You bring the AI, so its plan, key or hardware sets your cost and limits. |
| ZeroScript (free browser extension) |
Yes, through Studio's built-in MCP server: a Bridge you run on your PC links it to your AI chat. | Load its extension unpacked in Chrome or Edge, start the Bridge, and use a free AI chat (it recommends DeepSeek). | Free and open source (GPL-3.0), with no paid version and no sign-in. | Runs through a free AI web chat and a Bridge on your PC. Its site lists a Windows PC; its README also covers macOS. |
| RoCode (Studio agent) |
Yes, through its own plugin, not Studio's MCP server. Creates and edits scripts and instances, inserts ready-made UI kits and themed worlds, can compile-check its scripts and, with plugin 3.9 or newer, run a short playtest. | Free account, Creator Store plugin, desktop browser. Studio connects by itself on the same Roblox account, or with a pairing code. | Starter: 1 free credit a day, no card. Paid from $9.99 a month. | Its playtests (plugin 3.9 or newer, up to 30 seconds) take no screenshots; with plugin 3.9.14 or newer it screenshots only what it built, in edit mode. Its test character (plugin 3.9.11 or newer) checks only what the agent chose to test. It does not generate meshes from scratch, and it builds Terrain (hills, lakes, rivers and islands) for you but does not sculpt it by hand. |
| Ropilot (Studio agent) |
Yes, via its desktop app and plugin. Playtests, simulates input, takes screenshots. | Install Ropilot Studio (Windows, macOS, Linux). It adds the plugin. | Starter credits, or 500 actions a month on your own ChatGPT or Claude plan. | Needs its desktop app. Plus is $20 a month, credit packs from $8. |

| RoAgent (desktop app) |
Through its Windows desktop app and the Studio plugin it bundles. | Install the app on Windows 10 or later. macOS and Linux are listed as coming soon. | 250 actions a month, no card. One action is one tool call; a typical feature is about 80. | Needs a separate Claude or ChatGPT subscription: its plans do not include AI usage. Paid plans $10, $35 and $75 a month. |
| HyperDevs (desktop app) |
Through its Windows desktop app, in open beta. | Install the app, then add your own Gemini, Claude, OpenAI or z.ai key, a local Ollama model, or use its Hyper 30 model. | Your own key or Ollama is free and unlimited on its side. Hyper 30 has a free tier that resets daily, amount not published. | A Windows desktop app in open beta. |
| Picoo (paid plans only) |

| Ropanion (Studio plugin) |
Runs inside Studio as a plugin. | Install the free plugin from the Creator Store, then sign in. | Free built-in models; how much they cover is not stated. | Its developer says the free models suit prototyping and learning. Its listing says the plugin is not currently being updated. |
| RoAI (roai.studio) |
Yes, by its description: you prompt in its web Live Game Editor, approve a plan with a credit estimate, and its plugin applies the edits. | Create an account, link Roblox, then install its Creator Store plugin and link it. | Chat and plan previews are free. Building needs bought credits (the Free plan has 0 a month). | Priced in pounds, from £12 a month for 100 credits. Light, Standard and Deep runs cost about 20, 70 and 300 credits. |
| RoAssistant (roassistant.me) |
Yes, by its March 2026 DevForum post: scripts, UI and multi-part models, and it inserts Toolbox models. Its web app shows an Explorer view of your place. | Roblox sign-in only, plus its free Creator Store plugin. On 10 and 11 October 2026 its site said sign-in was switched off. | The plugin is free. On 10 October 2026 its site published no daily free amount. | One-off packs in US dollars, from $4.99 for 850 credits, no subscription. Its terms say all purchases are final. |
| RoStudio (rostud.io) |
Yes, by its homepage: scripts arrive in your place as they are built. Its terms say the plugin syncs scripts, the hierarchy and properties with its servers. | Sign in with Google or Roblox on its web app, then install its free Creator Store plugin. Marked beta on 15 October 2026. | 5 credits a day with a linked Roblox account, no card, on 15 October 2026. | Rostudio Starter $7.99 a month, Rostudio Plus $19.99. Its terms say all purchases are final and non-refundable, except where the law requires a refund. |
| Lemonade (Roblox agent) |
Yes, by a 6 October 2026 post from its partner Castform that Lemonade shared on X. Its Discord page describes two-way sync with Studio. | Sign in with Roblox only, then start from a prompt on its site. It also publishes a free Lemonade AI plugin on the Creator Store. | The plugin is free. Its public pages show no free amount and no prices. | Its terms: a monthly paid tier with higher prompt limits, no refunds. |
| SuperbulletAI (desktop app) |
Through its desktop app, which keeps a Rojo project on disk and syncs it into Studio. Existing places come in through an import feature. | Install the app (Windows or macOS), then connect Rojo and its Studio plugin. | 1M tokens a month, up to 150K a day. | Pro is $20 a month for 11M tokens. Its terms say all purchases are final and non-refundable. |
| Browser generator (for example Obby) |
No. Builds a new game you export to Studio as a .rbxlx file. | None. Runs in the browser. | Obby has a free tier. | A poor fit for a place you have already built. |
| Roblox Build (Roblox mobile app) |
No. Makes its own 2D and 2.5D games in the Roblox app. Editing one in Studio removes its Build status. | None. Open the Build tab in the Roblox mobile app, where it has rolled out (New Zealand first). | Free prompts every day; more credits for Robux. | Age-checked users 9 and older. Its docs say playtesting is coming soon. |
| Chatbot in a tab (ChatGPT, Claude, Copilot) |
No. It sees only what you paste. | None. | Claude and GitHub Copilot list free plans. | It guesses your object names, and you place every script. |
Inside Studio
Tools that work with Studio
These work with Roblox Studio rather than in a chat tab. Assistant, RoCode, Ropilot and Forge can read your hierarchy, find the script you already wrote and make a targeted change to it; for the others, each card says only what that tool's own pages state. If you have a game in progress, this is the shape you want, because the hard part is not writing Luau in the abstract, it is writing Luau that fits what you already have.

Roblox Assistant
Best for: trying AI in Studio with nothing to install and no extra account.
Roblox's own, built into Studio. It creates and edits scripts and objects, inserts Creator Store assets, and generates meshes, materials and procedural models. Roblox's docs also say it can run Luau, simulate input and playtest your game, and they describe a Planning Mode that shows its steps before it builds, a screen capture subagent that looks at the viewport in Edit and Play mode, and support for your own Anthropic, OpenAI or Google Gemini API key. It comes with Studio and its docs list no price, so it is the sensible first thing to try.
Source: Assistant for Studio, checked between 30 September and 10 October 2026.

RoCode
Best for: making changes in the place you have open from a web chat, with a free daily allowance and an undo point for each batch of changes.
A third-party agent. You describe a change in a web chat, and a free plugin from the Creator Store carries it out in your open place with 27 Studio tools that read, create, edit and check. It is told to compile-check each script it writes inside Studio, and when a check fails the run is sent back to fix it, up to two times, before it can finish. Each batch of changes is an undo point in Studio's own history, so undoing a longer run takes several presses of
Ctrl+Z. With plugin 3.9 or newer it can also press Play for a test of up to 30 seconds and read the errors and warnings, and with plugin 3.9.11 or newer control a test character to check the game works, but its playtests take no screenshots. With plugin 3.9.14 or newer it also takes screenshots of what it built, in edit mode, and can fix what looks wrong. Since October 2026 it also inserts premium UI kits in one step (25 screens, such as a HUD, pet inventory, store, daily rewards and egg hatching, in 5 themes, with working server scripts) and builds themed world islands (volcano, desert canyon, jungle or snow) in one call. RoCode facts has the plain details, and What RoCode can't do lists its limits.Source: RoCode's own docs and pricing page, 23 October 2026.
-
Ropilot
Best for: playtests that simulate input and capture the screen, Blender models and animations, or a ChatGPT or Claude plan you already pay for.
The closest thing to a direct alternative, and it has things RoCode does not. Its desktop app, Ropilot Studio, installs a Studio plugin. It can run a playtest, simulate input and capture what the player sees, and it makes 3D models and animations in Blender, which the app installs and drives. The app runs on Windows, macOS and Linux, and new accounts get free starter credits.

-
Forge
Best for: playtests that return a screenshot, on Windows, paid with prepaid credits that never renew.
A small Windows app, the Bridge, connects your open place to Forge's service through Studio's built-in MCP server. It playtests its own work and shows you a screenshot, lets you pick the model with the price shown before you send, and sells prepaid credit packs that never renew, with an optional monthly membership on top. It needs a Windows PC for now, and it was renamed ForgeBlox in October 2026. RoCode vs Forge compares the two.

RoGenie
Best for: the widest tool list and model choice, with playtests that take screenshots.
A Studio agent at rogenie.ai with a plugin you put in Studio's plugins folder and pair with a 6-digit code. Its home page lists 59 optional tools, from terrain and lighting to Toolbox insertion and animation, more than 60 built-in models plus your own keys, and a playtest that plays as a real player, takes screenshots and profiles performance. An optional Windows companion, the RoGenie Bridge, generates meshes, materials and textures. Use is counted in tokens per 5 hours and per month: free, then $5 to $99 a month. Its billing page says refund handling is not live yet. RoCode vs RoGenie compares the two.

Craftly
Best for: a one-click undo of whole builds, and a 7-day trial of a paid plan.
A Studio plugin from craftly.gg that builds from a sentence in the place you have open. It reads your place first, lints the scripts it writes, inspects the scene it built and scans for common Roblox mistakes; its pages do not mention a playtest. It gives 40 free credits once, then Pro at $14.99 a month and Ultra at $29.99, with a 7-day trial, and its refund policy says all sales are final. RoCode vs Craftly compares the two.

Kiwari
Best for: approving each change on a Mac, and generating meshes and textures.
A desktop app at kiwari.dev that works next to Studio rather than as a plugin. You approve each change unless you turn on Run everything, it plans larger tasks first, runs subagents in parallel, playtests, and generates models, meshes and textures. On 23 October 2026 its download page offered macOS only, with Windows coming. Kiwari Lite is free on one basic text-only model; Pro is $19.99 a month or $199 a year. RoCode vs Kiwari compares the two.

RoAgent
Best for: putting a Claude or ChatGPT subscription you already pay for to work in Studio, on Windows.
A desktop app for Windows 10 or later with a bundled Studio plugin; macOS and Linux are listed as coming soon. Its plans do not include AI usage, so you need a separate Claude or ChatGPT subscription. It counts usage in actions: one action is one tool call, and a typical feature is about 80.
Source: roagent.ai, read 11 October 2026.

HyperDevs
Best for: Windows users who want to bring their own Gemini, Claude, OpenAI or z.ai key, or run a local model through Ollama.
A Windows desktop app in open beta. Using your own key or a local Ollama model is free and unlimited on its side, and its own Hyper 30 model has a credit-billed free tier that resets daily.
Source: hyperdevs.app, read 11 October 2026.

Picoo
Best for: a fixed monthly credit amount, if you do not need a free tier.
Its FAQ says it has no free tier or free trial. Pro is $19 a month ($12 billed yearly) with 200 credits. How it works with Studio was not covered by our 11 October 2026 check.

Rebirth
Best for: a simple unit, where one credit is one prompt, with 5 free credits to try it.
Its terms say it delivers its features through a Roblox Studio plugin. New accounts get 5 free credits, then Hobby is $8.99, Pro $15.99 and Unlimited $29.99 a month. RoCode vs Rebirth compares the two.

Ropanion
Best for: prototyping and learning, which is what its developer says the free models suit.
A free Studio plugin with free built-in models, used after a sign-in. Its Creator Store listing says the plugin is not currently being updated, so check the listing before you rely on it.
Source: its Creator Store listing and DevForum post, read 11 October 2026.
-
RoAI
Best for: seeing a plan with a credit estimate before anything is built.
You prompt in its web Live Game Editor, approve a plan with a credit estimate, and its Creator Store plugin applies the edits. Chat and plan previews are free; building needs bought credits, priced in pounds. RoCode vs RoAI compares the two.
Source: roai.studio, read 9 October 2026.
-
RoAssistant
Best for: one-off credit packs with no subscription, after a Roblox sign-in.
A Studio plugin plus a web app at roassistant.me, not Roblox's built-in Assistant. Its March 2026 DevForum post says it makes scripts, UI and multi-part models and inserts Toolbox models, and its web app shows an Explorer view of your place. Its site had sign-in switched off on 10 and 11 October 2026, and on again by 30 October 2026. Is RoAssistant free? RoCode vs RoAssistant has its prices, refunds and models.

RoStudio
Best for: starting from a template, such as M1 combat or a run system, with a planning mode on its paid plans.
An AI web app at rostud.io with a free Studio plugin, not Roblox Studio itself. Its homepage says scripts arrive in your place as they are built, and its terms say the plugin syncs script contents, the instance hierarchy and property data with its servers until you disconnect it. On 15 October 2026 its free plan gave 5 credits a day with a linked Roblox account, Rostudio Starter was $7.99 a month, and its terms said purchases are final. RoCode vs RoStudio compares the two.

Lemonade
Best for: starting a game from a prompt on its site, signed in with your Roblox account.
Lemonade describes itself as an agent for making games on Roblox, with prompt suggestions such as a farm, pet or survival game. Its terms call it a middle layer between Studio and its own service, and its public pages show no prices. It publishes a free Lemonade AI plugin on the Creator Store, and a 6 October 2026 post by its partner Castform, which Lemonade shared on X, says its agent builds in your Studio place, for a new game or a new mechanic in an existing project. Lemonade alternatives covers the rest.

SuperbulletAI
Best for: working from a Rojo project on disk that syncs into Studio.
A desktop app for Windows or macOS that keeps a Rojo project on disk and syncs it into Studio through Rojo and its plugin; existing places come in through an import feature. RoCode vs SuperbulletAI compares the two.
Source: superbullet.ai, read 9 October 2026.
The practical differences come down to three things. Playtests: Assistant, Ropilot, Forge and MCP clients can run one and also simulate input or capture the screen. RoCode, with plugin 3.9 or newer, runs a short playtest that reads errors and warnings, and with plugin 3.9.11 or newer it can control a test character to check the game works, but its playtests take no screenshots. Platforms: Forge needs Windows, Ropilot's app runs on Windows, macOS and Linux, and RoCode needs Roblox Studio on Windows or Mac plus a desktop browser. Cost: Assistant comes with Studio, Ropilot and Forge sell their own credits, and RoCode has a free daily allowance with monthly plans above it. Each tool counts credits in its own unit, so compare prices, not credit counts.
Through Studio's MCP server
Tools that connect your own AI to Studio
Studio ships with a built-in MCP server that lets an outside AI work in the place you have open. Turn it on in Assistant under … > Manage MCP Servers > Enable Studio as MCP server. Roblox warns that connected clients can read and modify content in your open places, so connect only ones you trust.
-
Studio MCP server with your AI client
Best for: using an AI client you already have, such as Claude Code, Cursor or Codex CLI, with Roblox's own Studio tools.
Roblox's quick connect list includes Antigravity, Claude Code, Claude Desktop, Codex CLI, Cursor, Gemini CLI and Visual Studio Code. Connected, a client can read your scripts and hierarchy, change the open place, start playtests and simulate input, and you pay that client's maker. Our Studio MCP guide walks through the setup, and how to use AI in Roblox Studio compares every option.

BloxBot
Best for: running a Studio agent on your own computer with the model you choose.
A free, MIT-licensed desktop app for Windows, macOS and Linux that connects your own model to Studio's built-in MCP server, with no plugin to install. It works with a ChatGPT Plus or Pro sign-in, an API key, or a local model. RoCode vs BloxBot compares the two.

ZeroScript
Best for: using a free AI web chat you already have, such as DeepSeek, as a Studio agent.
A free, open-source (GPL-3.0) browser extension with no paid version and no sign-in. You load it unpacked in Chrome or Edge and start its Bridge on your PC, which drives Studio's built-in MCP server from your AI chat. Its site lists a Windows PC and a free DeepSeek account as requirements, and its README also covers macOS. RoCode vs ZeroScript compares the two.
Its official site is zerodev.tools/zeroscript. Copycat sites exist, and any site that asks for your Roblox cookie is a scam.
Source: zerodev.tools/zeroscript and its GitHub README, read 11 October 2026.
Browser generators
Tools that build a game from a prompt
These run in a browser or the Roblox app and turn a description into a playable game. They are genuinely good at the blank page: if you are starting from nothing and want something playable to look at, they get you there without installing anything. The trade-off is the other direction: they generate a project rather than working inside yours, so they are a poor fit once you have a place you have already put real time into.
-
Obby
Best for: a playable first draft from a blank page, exported to Studio.
It previews the game in the browser, exports a .rbxlx file you open in Studio, and covers genres such as obbies, tycoons and pet simulators. It has a free tier for your first games.
Source: obby.fun and its FAQ, checked between 30 September and 11 October 2026.

Roblox Build
Best for: a simple 2D game made on a phone and published with one tap.
Roblox's own AI game maker, in the Build tab of the Roblox mobile app. Its docs say it makes 2D and 2.5D games, best with clickers, arcade games and side-scrollers, gives free prompts every day with more credits for Robux, and publishes with one tap after a safety check. It is for age-checked users 9 and older and was rolling out region by region, starting with New Zealand. Its docs say playtesting is coming soon, and editing a Build game in Studio removes its Build status for good. It is not Roblox Assistant, the AI inside Studio. RoCode vs Roblox Build compares the two.
Source: Create games with Build, read 23 October 2026.
General chatbots
ChatGPT, Claude and Copilot
Best for: explaining code and debugging a snippet you paste in.
They write reasonable Luau, and they are good at explaining why something does not work.
In a browser tab the limitation is structural rather than a quality problem: they cannot see your place. They do not know your instance paths, your existing scripts or your naming conventions, so every answer arrives as a block of code you then have to translate into your project. That translation step is the actual work, and it is the step the in-Studio tools remove.
That changes if you connect a desktop AI client, such as Claude Code or Codex CLI, to Studio's built-in MCP server, as the MCP section describes.
If you use Assistant
Roblox Assistant alternatives
Assistant is the default for good reasons. Here is when to stay with it, and what to use when it is not enough.
What it is. Roblox's AI helper, built into Studio. It writes and edits scripts and objects in your data model, inserts Creator Store assets, generates meshes and procedural models, and can plan before it builds. Under Manage API Keys you can switch it to your own Anthropic, OpenAI or Google Gemini key.
Who should stay. Anyone it is working for. It comes with Studio, its docs list no price, it needs no install, it can playtest, and it already lets you change the model. Its docs state one cap, 50 procedural models per rolling 24 hours, and do not publish a message limit. If you hit a limit the docs do not describe, they offer no way to raise it, and the two routes below are the realistic ones. Assistant limits covers what the docs do and do not say.
Same Studio, a different AI client. In Assistant, open the … menu, choose Manage MCP Servers and turn on Enable Studio as MCP server, then connect Claude Code, Cursor, Codex CLI or another client. You get Roblox's own tools, including playtests and input simulation, driven by the client you choose, and you pay that client's maker. The Studio MCP guide has the steps.
A third-party Studio agent. RoCode, Ropilot and Forge all work in your open place with their own interface and pricing. RoCode runs from a web chat with a step-by-step log and a free daily allowance. With plugin 3.9 or newer it runs short playtests that read errors, while Ropilot and Forge also simulate input or take screenshots. With plugin 3.9.14 or newer, RoCode takes screenshots only of what it built, in edit mode. RoCode vs Roblox Assistant compares the two in detail.
If you use Ropilot
Ropilot alternatives
Ropilot covers a lot: playtests, Blender models and your own ChatGPT or Claude plan. The right alternative depends on which part you use.
What it is. A desktop app, Ropilot Studio, for Windows, macOS and Linux that installs a Studio plugin. It reads and edits your scripts, runs playtests with input simulation and screenshots, and makes 3D models and animations through Blender. You pay with Ropilot Credits (Plus is $20 a month, packs start at $8), or connect your own ChatGPT or Claude plan and pay for Ropilot Actions, with 500 a month free.
Who should stay. If you rely on its playtest loop, on Blender models and animations, or on putting a ChatGPT or Claude subscription you already pay for to work in Studio, Ropilot covers that directly. RoCode makes no Blender models and does not use a ChatGPT or Claude plan, and its short playtests take no screenshots, though with plugin 3.9.11 or newer its test character can check that things work.
Alternatives that also simulate input or take screenshots. Roblox Assistant is built into Studio, and Roblox's docs say it can playtest and simulate input. Forge playtests and returns a screenshot, on Windows, with prepaid credits and no subscription. Or connect Claude Code or Codex CLI to Studio's own MCP server, which has playtest and input tools built in, and pay only for your AI client.
Alternatives if short playtests are enough. RoCode works from a web chat and a Creator Store plugin with no desktop app, and with plugin 3.9 or newer runs short playtests that read errors, with a test character on plugin 3.9.11 or newer. It has a free Starter plan with 1 free credit a day, and paid plans from $9.99 a month. RoCode vs Ropilot goes through the differences.
Alternatives that use your ChatGPT or Claude plan. RoAgent's Windows app runs on a Claude or ChatGPT subscription you pay for separately, with 250 actions a month free on its side. BloxBot, free and open source, works with a ChatGPT Plus or Pro sign-in, an API key or a local model, on Windows, macOS or Linux.
If you use Lemonade
Lemonade alternatives
This section uses Lemonade's own home page, terms, privacy policy, Creator Store listing and Discord page, and a post by its partner Castform, all read 15 October 2026.
What it is. Lemonade describes itself as an agent for making games on Roblox. You sign in with your Roblox account and start from a prompt on its site, with suggestions such as a farm, pet or survival game. It publishes a free plugin, Lemonade AI, on the Roblox Creator Store, and its Discord page describes two-way sync with Studio. Its terms describe it as a middle layer between Roblox Studio and its own service, and say your project files live on Roblox. A 6 October 2026 post by its partner Castform, which Lemonade shared on X, says the agent builds in your Studio place, for a new game or a new mechanic in an existing project.
Who should stay. If starting from a prompt on its site suits the games you make, there is no reason to move. Before you pay, note that its public pages show no prices, and its terms describe a monthly paid tier with higher prompt limits and payments that are final and non-refundable.
For a new game from a prompt. A browser generator such as Obby does that job with a free tier: it previews the game in the browser and exports a .rbxlx file you open in Studio.
For a place you already have. Roblox Assistant is built into Studio. RoCode, Ropilot and Forge all work in your open place and publish their prices: RoCode from $9.99 a month with a free daily allowance, Ropilot Plus at $20 a month, Forge credits from $10. RoCode refunds any payment in full if you ask within 14 days. RoCode vs Lemonade compares the two.
Choosing
Which one you actually want
-
You have a game in progress
Use something that works in your open place: Assistant, a Studio agent or an MCP client. A chatbot tab or a browser generator cannot see it.
-
You are starting from nothing
A browser generator gets you something playable without installing anything. Move to a tool that works in Studio once the project is real.
-
You want to understand the code
A general chatbot is genuinely good at this and costs you nothing extra if you already pay for one.
-
You want automated playtesting
For tests that simulate input or show you the screen, look at Roblox Assistant, Ropilot, Forge or an MCP client. RoCode, with plugin 3.9 or newer, runs short playtests that catch errors, and with plugin 3.9.15 or newer its test character can also walk, press keys and click on-screen buttons.
-
You do not want to install anything
Try Roblox Assistant first. It is built into Studio.
-
You want to try before paying
Assistant comes with Studio, RoCode's Starter plan gives 1 free credit a day, Ropilot and Forge give trial credits, RoGenie and Kiwari have free tiers, Craftly gives 40 credits once, and Obby and Roblox Build have free tiers.
-
You already pay for Claude or ChatGPT
Ropilot's Bring Your Own AI plan and RoAgent put that subscription to work in Studio, and BloxBot accepts a ChatGPT Plus or Pro sign-in. Claude Code and Codex CLI can also connect to Studio's MCP server.
-
You want free and open source
BloxBot (MIT) and ZeroScript (GPL-3.0) cost nothing and connect an AI you bring to Studio's built-in MCP server.
-
You want to use your own API key
Assistant takes an Anthropic, OpenAI or Google Gemini key, HyperDevs a Gemini, Claude, OpenAI or z.ai key or a local Ollama model, BloxBot an API key or a local model, and RoCode an OpenRouter key on any paid plan.
Questions
Common questions
What is the best AI for Roblox scripting?
It depends on the job. To add features to a place you already have, use something that works inside Studio: Roblox Assistant first, because it is built in, then an MCP client or a third-party Studio agent if you want a different workflow or price. From a blank page, a browser generator gets you a playable draft without installing anything. A chatbot in a tab is good at explaining code but cannot see your project.
Can I just use ChatGPT or Claude for Roblox scripts?
Yes, and for explaining a concept or debugging a snippet you paste in they work well. In a browser tab they cannot see your place, so you do the translating. Connected to Studio's built-in MCP server, desktop clients such as Claude Code or Cursor can read and edit the open place, after some setup.
Do Roblox AI plugins work on an existing game?
Tools that work inside Studio do. Roblox Assistant, MCP clients and Studio agents such as RoCode, Ropilot and Forge read your hierarchy and edit the scripts already there. Browser generators usually build a new project and export it, which fits an existing place badly.
Is there a free AI plugin for Roblox Studio?
Roblox Assistant is built into Studio rather than a plugin, and its docs list no price. Among third-party tools, RoCode's Starter plan gives 1 free credit a day and all 27 Studio tools, no card needed, and Ropilot and Forge give trial credits. BloxBot and ZeroScript are free and open source but run on an AI you bring, and Ropilot's Bring Your Own AI plan (500 Ropilot Actions a month) and RoAgent's free plan (250 actions a month) run on a Claude or ChatGPT subscription you pay for separately. Every free tier is compared in free AI for Roblox Studio.
Is there a free AI that makes a Roblox game?
Yes, a few, for different jobs. Roblox Build, in the Roblox mobile app, makes simple 2D and 2.5D games from prompts, with free prompts every day where it has rolled out. In Roblox Studio, RoCode's Starter plan gives 1 free credit a day with no card and builds 3D games one round at a time in the place you have open, RoGenie and Kiwari have free tiers, and Craftly gives 40 credits once. Browser generators such as Obby have free tiers and export a place file.
What is the best alternative to Roblox Assistant?
To stay with Roblox's own tooling, connect Claude Code, Cursor or Codex CLI to Studio's built-in MCP server, or add your own Anthropic, OpenAI or Google Gemini key to Assistant. For a separate agent, RoCode, Ropilot and Forge all work in your open place. Ropilot and Forge playtest with simulated input or screenshots, as Assistant can. RoCode, with plugin 3.9 or newer, can run a short playtest that reads errors, and with plugin 3.9.11 or newer it can control a test character to check the game works. Its playtests take no screenshots, but with plugin 3.9.14 or newer it screenshots what it built, in edit mode. Which fits best depends on your computer, your budget and how much playtesting you need.
What are the alternatives to Ropilot and Lemonade?
Roblox Assistant is built into Studio and can playtest. Forge playtests too, on Windows, with prepaid credits. RoCode works in your open place from a web chat, with a free daily allowance, and with plugin 3.9 or newer runs short playtests that read errors, with a test character on plugin 3.9.11 or newer. Its playtests take no screenshots, but with plugin 3.9.14 or newer it screenshots what it built, in edit mode. For a new game from a prompt, a browser generator such as Obby exports a place file you open in Studio.
