🤖 The Ballerina AI Assistant: Your Intelligent Co-Pilot

Ballerina AI

What sets this Playground apart is the integrated AI Assistant, powered by Google Gemini and OpenAI.

This is more than a chatbot — it’s a real-time Ballerina expert, making learning and debugging fast and intuitive.

Quick Actions:

  • Explain Code: Detailed, line-by-line explanations of your Ballerina logic
  • Fix Errors: Suggestions to resolve compilation/runtime errors
  • Optimize: Professional tips for performance and best practices
  • Help: Ask about syntax, modules, error handling, or any Ballerina concept

You can click the quick-action buttons or ask custom questions in chat.
AI-suggested code can be inserted directly into the editor with Insert Code, providing a seamless workflow.

📌 AI is fully context-aware and trained using ballerina.io documentation.

🧹 Real-Time Code Quality with Ballerina Lint

Maintaining high code quality is crucial.
The Playground integrates a Best Practices Checker inspired by the Ballerina Lint VS Code Extension.

As you type, the linter provides real-time feedback on:

  • Code quality
  • Ballerina best practices
  • Recommended conventions

🔒 Security and Limitations

The Playground is built with strict sandboxing:

  • No internet access
  • Isolated environment
  • Limited resources
  • Read-only file system

Disabled for security reasons:

  • HTTP clients
  • WebSockets
  • External APIs
  • Database connections
  • File system access
  • Services/listeners

This ensures a safe and stable environment for execution.
