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
