RbxSync – The AI-Native Sync Tool for Roblox Studio

Why RbxSync

The Only Sync Tool With Native AI Integration

One Source of Truth

Everyone syncs from Git. No more passing around .rbxl files. No more asking "is this the latest version?" Code review your game changes. Branch and merge like real software.

Full Property Extraction

Captures ALL properties using Roblox API dump reflection. Parts, MeshParts, Attachments, Scripts. Every class, every property.

True Two-Way Sync

Edit in Studio, changes appear in files. Edit in VS Code, changes appear in Studio. Real-time, automatic, bidirectional.

Multi-Studio Sessions

Run multiple Studio instances, each synced to different projects simultaneously.

Console Streaming

See print(), warn(), and error() output in your terminal.

Build to .rbxl/.rbxm

Build place or model files from your project. Watch mode auto-rebuilds.

Sourcemap Generation

Generate sourcemap.json for Luau LSP. Full IntelliSense in VS Code.

MCP Integration

Claude and Cursor can build, test, and debug your game autonomously.

E2E Testing

Run live playtests from CLI. Capture console output for verification.

Exclusive to RbxSync

One Click. Your Entire Game in Git.

Open any game in Studio. Click Extract. 50,000 instances become one datamodel.rbxjson, plus real .luau scripts. Every property captured in seconds. Zero data loss. No other tool does this.

AI-Native Development

Build, Test, and Iterate - Autonomously

AI agents write code. Run playtests. See errors. Fix them. Repeat. RbxSync streams console output directly to your terminal or MCP-connected agent. The feedback loop that makes AI-assisted development actually work.

✓ Real-time console streaming to terminal

✓ MCP tools for AI agent integration

✓ Execute Luau code remotely in Studio

✓ Run playtests and capture output

✓ Autonomous debug → fix → test loops

File Format

One context file. Real Luau. Git-friendly.

Scripts are real .luau files. Your whole tree lives in one datamodel.rbxjson. A hidden, read-only context file with explicit types: every instance, every property. Review the .luau diffs. Zero data loss.

datamodel.rbxjson

{
  "className": "DataModel",
  "name": "DataModel",
  "children": [
    {
      "className": "ServerScriptService",
      "name": "ServerScriptService",
      "children": [
        {
          "className": "Script",
          "name": "Main",
          "sourcePath": "src/ServerScriptService/Main.server.luau"
        }
      ]
    }
  ]
}

Why .rbxjson?

A format designed for real-world workflows.

RbxSync (.rbxjson)

{
  "className": "Part",
  "properties": {
    "Size": {
      "type": "Vector3",
      "value": { "x": 4, "y": 1, "z": 2 }
    },
    "Anchored": {
      "type": "bool",
      "value": true
    }
  }
}

+ Clean Git diffs - see exactly what changed
+ Explicit types - no ambiguity
+ AI/LLM readable - agents can parse and modify
+ One context file - your whole tree in one place

Traditional (.rbxmx / XML)

<Item class="Part">
  <Properties>
    <Vector3 name="Size">
      <X>4</X>
      <Y>1</Y>
      <Z>2</Z>
    </Vector3>
    <bool name="Anchored">true</bool>
  </Properties>
</Item>

- Verbose - more lines for same data
- Noisy diffs - hard to review in PRs
- Harder for AI to parse reliably
- Error-prone manual editing
