Pro Code Playground: Your Free AI-Powered Multi-Language Code Editor

Need a versatile, free, and AI-powered code editor? Pro Code Playground is an open-source, web-based solution supporting multiple languages, in-browser code execution, and a built-in AI coding assistant.

What Pro Code Playground Offers:

Write, run, and debug code in Python, C, C++, Java, JavaScript, and C#.
Upload your own code files (.py, .java, .cpp, etc.).
Syntax highlighting and ACE editor integration for a smooth coding experience.
Customizable light/dark mode to suit your preference.
A built-in AI Assistant (powered by Groq’s LLaMA 3.3) to analyze code, explain errors, answer coding questions, and even narrate explanations using Edge TTS.

AI Assistance at Your Fingertips:

The integrated AI assistant isn’t just a code checker. It’s a helpful companion that can break down complex concepts, explain errors in plain English, and even talk you through the logic using Edge TTS. It’s like having a coding buddy available 24/7.

How It Works:

Pro Code Playground leverages a robust tech stack: Python, Streamlit, LangChain, Groq LLaMA 3.3, and Edge TTS power the core functionality and AI assistance. OneCompiler API handles backend execution for Java, JavaScript, and C#.
