AI-assisted Roblox development. BloxBot is a free, open-source desktop app that connects any AI model to Roblox Studio's official MCP server, so you can build games by describing what you want.

• Chat with AI models (Claude, GPT, Gemini, and more) that can read and modify your Roblox Studio project in real time
• Create scripts, build UI, manipulate the explorer hierarchy, edit properties - all through natural language
• Uses Roblox Studio's built-in MCP server, giving the AI structured access to Studio. No plugins to install
• Bring your own API key from any supported provider, or connect via OAuth

BloxBot connects two things:

1. A desktop app (Electron, Effect, and React) where you chat with AI
2. An AI server (OpenCode) that manages model connections, sessions, and tool use

The AI connects to Roblox Studio through its official built-in MCP server. When you type a message, the AI uses MCP tools to directly inspect and modify your open Studio project.

Download the installer for your platform from the releases page:

1. Install and open BloxBot
2. Open Roblox Studio and open (or create) a place
3. In Studio, open Assistant settings (three-dot menu) → MCP Servers → enable Studio as MCP server
4. Connect an AI provider in BloxBot's Settings → Providers
5. Start building

macOS: The app is signed and notarized. Open the .dmg and drag BloxBot to Applications.

Production builds require VITE_POSTHOG_PROJECT_TOKEN. Copy .env.example to .env.local for local packaging. GitHub Actions injects the public project token from the POSTHOG_PROJECT_TOKEN repository variable when building release artifacts.

On first launch, BloxBot downloads the newest compatible OpenCode 1.x.x release and verifies its SHA-256 digest. Later launches check for compatible minor and patch updates and can fall back to the newest verified cached copy when offline.
