Hey! I'm a solo dev. I made Bricklayer for the Roblox community, so you can build the game in your head without the setup getting in the way.

The professional Roblox workspace.

A real codebase, the agents you trust, and a live connection to Studio. Go from an idea to reviewed code and a game you can play.

ChatGPT

Writes it. Hardens it. Playtests it.

  1. Write
  2. Harden
  3. Playtest
  4. Iterate

Your game, as a real codebase.

Work in ordinary Luau files with a project structure your team and tools can understand. Review a diff, create a branch, or go back to a version that worked. It is all built into the editor.

  • Typed Luau and real file paths
  • Native Git, branches, and clean diffs
  • Two-way sync with Roblox Studio

From Studio to your next release.

Make your first game
  1. 01

    Connect your place

    Open your Studio project and mirror its scripts into a structured Luau codebase. Keep the editor and Studio in sync as you work.

  2. 02

    Build together

    Write code yourself or hand a task to your agent. Your team works in the same repository, with shared context and clean diffs.

  3. 03

    Review. Playtest. Repeat.

    Inspect the changes, commit the work, and test it in Studio. Let the next playtest inform the next iteration.

One codebase. Every agent you trust.

Bring the coding agents you already use. They work alongside you in the same files, on the same branch, with the same live Studio connection. Every contribution stays visible and reviewable.

Any ACP agent. One editor chat.

Bring any agent that supports the Agent Client Protocol (ACP). Pick the agent and model for each chat, give it a task, and review its changes right in the editor.

Claude Code, Codex, Google Antigravity, opencode, Qwen Code, and GitHub Copilot CLI are built in. You can also connect an API model or run one locally with Ollama.

Choose your AI setup
Bricklayer Chat with the agent picker open. Your providers lists Ollama minimax-m3.1-flash:cloud, OpenAI gpt-4.1, and OpenRouter openrouter/free. External agents (ACP) lists Claude Code, Codex, Google Antigravity, opencode, Qwen Code, GitHub Copilot CLI, and a custom command.

Animations, from a sentence.

Ask for a wave, a crouch, or a sword swing. Your agent plans the beats, writes the clip, and plays it back next to the chat. Then it checks its own work before anything reaches Studio.

Works with R15, R6, and custom Motor6D rigs in your place. Early release: you publish the finished clip from Studio.

  • Saved as a readable file in your project
  • Previewed on a live character as it is written
  • Checked for clipping, foot slide, and joint limits
  • Staged in Studio as a native KeyframeSequence

Your agent, inside Roblox Studio.

Prefer to stay in Studio? Run your coding agent in the Bricklayer dock, right next to the viewport. The Agent Client Protocol connects the agent you already use to the game you are building.

Built-in presets for Codex, Gemini CLI, opencode, Qwen Code, and GitHub Copilot CLI. Connect Claude Code or another ACP agent by command.

Your account

Sign in to your agent as usual. It runs as its own program, using your existing account and plan.

All 55 Bricklayer tools: edit scripts, inspect the data model, run tests, take screenshots, and start a playtest.

Changes you control

Review Allow and Deny cards with diffs. Changes inside Studio stay undoable with Ctrl+Z.

How Bricklayer compares

Most Roblox AI tools live inside Studio as a plugin, which makes them easier to start and harder to leave. Bricklayer takes the other trade: you install an editor, and in return your game becomes a real codebase that your own agent can read, edit, and playtest, in files you keep.

Give Bricklayer some love.

Bricklayer is built with late nights, carefully placed bricks, and a concerning amount of hot cocoa. If it has helped you build, leave a heart.

“Bricklayer is a niche and super cool tool to use. For a builder and modeler like me that doesn't know anything about scripting, Bricklayer does the tough and tedious scripting to make my ideas remotely possible. Bricklayer is also relatively easy to install and set up, but even easier to use, and it's not just scripting, it can make nice looking maps too.”

A few useful answers.

Do I need to know how to code?
No. You describe the game and review what the AI proposes. Reading the changes teaches you more Luau than you would expect, and you can take over by hand whenever you want.
Is this against Roblox rules? Could I get banned?
Bricklayer edits files on your own computer and talks to Roblox Studio through its official plugin system. It does not automate the Roblox player, use exploits, or publish anything on your behalf. Publishing stays a deliberate action you take in Studio, so what you ship is your call and your responsibility.
Will it break the game I already have?
Bricklayer asks you to confirm the right game before it copies anything, and every file change is shown as a before-and-after diff you approve. Changes made inside Studio are undoable, and since the project is a normal folder, Git works on it too. Opening an existing game walks through it.
How much does it cost?
The editor is free. You bring your own AI, and that can be free too. Every free option is listed here.
Do I still need Roblox Studio?
Yes, and you should keep it open. Studio stays the place editor and the only way to press Play. Bricklayer handles the scripts and keeps both sides in sync while you work.
Why does Windows warn me when I install it?
The beta is not code signed yet, so Microsoft Defender SmartScreen may show a blue warning. Choose More info, then Run anyway. There is no macOS build right now; request one on the downloads page.
What if I get stuck?
Run Bricklayer Setup / Diagnostics. It checks the project, the Studio connection, file sync, and your AI provider in one pass and tells you which one failed. Recovery guide.
