**Short answer:** you can make a Roblox game without coding by describing it to an AI that writes the Luau scripts and builds the parts inside Roblox Studio. With the free Synagy plugin (beta), you install one app, sign in, describe an obby or tycoon, check the price of the plan and press Build. Roblox's own Assistant and Build are alternatives.

We make Synagy, so we describe our own steps in detail and the other options from their public pages. Where an option is better, we say so.

## How do you make a Roblox game without coding, step by step?

You need Roblox Studio, a free Roblox account and a free Synagy account. The Synagy app can install Studio if it is missing.

**Install the Synagy app | One click: it finds Roblox Studio and puts the plugin in place**

1. **Sign in once**: Click "Sign in with synagy.org" in Studio and confirm the code on synagy.org/link
2. **Describe your game**: An obby, a tycoon, a simulator, or a change to the place you have open
3. **Check the plan**: Every part is listed with its price in credits, then press Build
4. **Watch it build**: Scripts are written and syntax-checked, the world is built, and a playtest runs with an avatar

After the build, play it in Studio. If something is off, type what to change, for example "make the lava rise slower". Every change is one undo step, so Ctrl+Z works.

When you are happy, publish from Studio the normal way, with File and Publish to Roblox. Synagy does not publish for you.

## What does it cost?

Synagy is in a free beta, and payments are paused. Every account gets 25 Free Credits a day, and the plugin is free. The plan shows its price in credits before anything is built, and a part that fails costs nothing. Planned paid plans start at €2.99 a month (Go) but cannot be bought yet. Current numbers are on the [pricing page](https://synagy.org/pricing).

## What can't it do yet?

The Roblox plugin is a beta, so be careful with it.

- **No images or meshes.** Roblox needs images and meshes uploaded as assets to your account first, so Synagy builds with parts, scripts and what is already in your place.
- **No multiplayer tests.** A plugin cannot start them, so a playtest has one avatar.
- **It changes your place.** It can edit and delete parts and scripts, so save a copy first. The Synagy window asks you to confirm this once.
- **It is young.** We test in Roblox Studio 0.741, and the plugin is still young on Windows and macOS.

> **Tip:** start with one small idea, such as an obstacle course with ten jumps. You see within minutes how the AI understands your words.

## What are the other ways to build without code?

| Option | What it is | Limits | Source |
|---|---|---|---|
| Roblox Assistant with Studio | Chat, plan mode, mesh and material generation inside Studio | Needs more Studio knowledge than a one-line prompt | [Roblox docs](https://create.roblox.com/docs/assistant/guide) |
| Roblox Build | Make a game from text in the Roblox app; public alpha since 2026-07-28 | Region-limited alpha, age-verified users, games live on Roblox | [TechCrunch](https://techcrunch.com/2026/09/11/roblox-is-making-it-easier-to-build-games-with-ai-and-play-them-outside-roblox/) |
| Synagy plugin | A window in Studio that plans, builds and playtests | Beta, no images or meshes | [Roblox page](https://synagy.org/roblox) |

Roblox's own tools are better if you want AI-generated meshes today, because Synagy cannot make them yet. Roblox Build is better if you do not want to open Studio at all.

If you already use Claude Code, Codex or Cursor, you can skip the window and let your agent drive Studio. We compare those servers in [Roblox Studio MCP servers compared](https://synagy.org/blog/roblox-studio-mcp-servers-compared).

## FAQ

### Can I make a Roblox game without knowing Luau?

Yes. Roblox runs on Luau, but an AI can write it from your description. You still decide what the game is, and you test it in Studio. Basic Studio skills, such as moving around the viewport, help a lot.

### Is Synagy for Roblox free?

The plugin and the MCP server are free, and every account gets 25 Free Credits a day during the beta. You see the price in credits before a build, and a failed part costs nothing. Paid plans are planned but not on sale yet.

### Do I need an AI agent like Claude Code?

No. The Synagy window runs in the Synagy cloud, so you only need Roblox Studio and a free Synagy account. A coding agent is optional for people who already use one.

### Does Synagy make images, meshes or sounds for Roblox?

Not yet. Roblox requires images and meshes to be uploaded as assets to your account, so for now Synagy builds with parts, scripts and what already exists in your place.
