What You Can Do

01
Free AI

Full Power of AI — For Free

Access the complete AI-powered game development toolkit at zero cost. No subscriptions, no usage caps, no paywalls. Apache-2.0 licensed and open source.

02
Smart Tokens

Efficient Token Consumption

Optimized MCP protocol minimizes AI token usage per operation. Get more done with fewer tokens — your AI budget goes further with every interaction.

03
Pro Tools

Advanced AI Tools

Production-grade tools for scene manipulation, asset generation, component editing, script execution, and more — all controllable through natural language.

04
Build Your Own

Custom AI Tools

Create your own MCP tools that AI agents can discover and use. Extend the platform with domain-specific actions tailored to your game and workflow.

05
Ship Faster

Rapid Iteration

AI accelerates every development cycle. Changes appear in your editor in real time — prototype, test, and refine at a pace impossible without AI.

06
Any Agent

All Popular AI Agents

Works with Claude, Cursor, Codex, Gemini, GitHub Copilot, VS Code, Rider, and more. Use whichever AI you prefer — they all connect through MCP.

07
Local Mode

Local-First Privacy

Runs entirely on your machine. No cloud dependency, no third-party services, no data leaving your dev environment. Full control over your workflow.

08
Cloud Ready

Cloud-Connected Gameplay

Connect your game mechanics to the cloud so AI can trigger, invoke, and orchestrate them remotely. Perfect for live game services and remote testing.

Pricing

Free forever. Go Pro when you’re ready.

The App and every engine plugin are free and open source — run everything locally at no cost, no account required. Upgrade to Pro only when you want hosted AI: higher limits, premium models, and zero setup, right from the App.
