What's inside

Everything a vibecoded
Roblox game needs.

Studio, wired in

Your agent can see and edit your place.

Brickyard hands the Roblox Studio MCP server to the agent on every run, or uses the one already in its config. No setup, no duplicate tools.

Studio · script_search"RoundService"✓
Studio · multi_editServerScriptService✓
Studio · start_stop_playplay

Model chooser

Pick the model, per thread.

The list comes straight from each CLI, so you only see models your account can run.

Sonnet 5.5 balanced
Opus 5.5 deep work
gpt-6-luna codex
grok-4.7 default

Your keys stay yours

Nothing to sign up for.

Brickyard runs the CLIs you are already signed in to. It never sees a key and never sends your code anywhere.

Code panel

See every change.

A file tree, a highlighted viewer, and git diffs that refresh after every turn.

-local phase = nil
+local state = { phase = "Intermission" }
+state.timer = 15

Three access levels

Plan, Edit, or Full.

Let an agent only plan, edit files and Studio safely, or run with no checks on a project you have backed up.

Agents calling agents

Get a second opinion
without switching apps.

Claude or Codex can hand a task to any other agent you have connected: a review, a quick fix, a different take. Each call runs on that agent's own account and comes back as a card in your thread.

  • Called agents work in the same project
  • They never get Studio access
  • Turn it off any time in Settings

Get going

Three minutes to your first build.

  1. 01

    Install an agent

    Sign in to Claude Code, Codex, Gemini, OpenCode or Grok once in a terminal. Brickyard finds it.

  2. 02

    Open your place

    Start Roblox Studio and point Brickyard at your project folder. Rojo projects work best.

  3. 03

    Describe the change

    "Add a round system." The agent reads your scripts, edits Studio, and shows you every step.

Questions

Good to know.

Is it really free?

Yes. Brickyard is MIT licensed and has no account. You pay your agent providers directly, the same as you do now.

Which agents does it support?

Chat works with Claude, Codex, Gemini, OpenCode and Grok. Cursor, Muse Code and Pi are detected but cannot chat yet.

Does Brickyard see my API keys or code?

No. It starts the agent CLIs already on your PC and reads their output. Threads are stored only on your machine.

Why does Windows warn me when I install it?

The beta installer is not code signed yet, so SmartScreen shows a warning. Choose "More info", then "Run anyway".

Can an agent break my game?

It can, which is why there are access levels. Studio has no undo for agent edits, so save a copy of your place before big changes.

Mac or Linux?

Not yet. The beta is Windows only. The code is open if you want to help.
