A Full-stack code generation platform. Describe what you want, get production-ready code with tests and docs.

Generates code in 10 languages (Python, JavaScript, TypeScript, Java, C#, Go, Rust, C++, Ruby, Swift) using OpenAI's GPT-4. Includes automatic test generation with framework detection and inline documentation. Users provide their own API key stored locally in browser.

cd backend python -m venv venv source venv/bin/activate # Windows: venv\Scripts\activate pip install -r requirements.txt uvicorn main:app --reload --port 8000

cd frontend npm install npm run dev

Open http://localhost:3000

1. Add your OpenAI API key (stored locally in browser)
2. Enter what you want to build
3. Select programming language
4. Generate code, tests, and documentation
5. Copy or download results

Frontend (Next.js + TypeScript) ↓ HTTP + Auth Header Backend (FastAPI) ↓ User's API Key OpenAI GPT-4 

User's OpenAI API key stored in localStorage, sent in Authorization header. Backend creates separate LangChain instance per request with provided key.

• POST /api/generate - Generate code (requires Authorization: Bearer <api_key>)
• POST /api/analyze - Analyse code quality
• GET /api/languages - Supported languages
• GET /api/health - Health check

Backend (.env):

# Optional - users provide their own OPENAI_API_KEY="" API_HOST=0.0.0.0 API_PORT=8000 CORS_ORIGINS=["http://localhost:3000"]

Frontend (.env.local):

NEXT_PUBLIC_API_URL=http://localhost:8000/api

Backend: FastAPI, LangChain, OpenAI API, tree-sitter, Pydantic Frontend: Next.js 15, React 19, TypeScript, Tailwind CSS, Framer Motion

• Multi-language support with framework-specific test generation
• Code quality metrics (complexity, readability, performance)
• Syntax validation using tree-sitter AST parsing
• Matrix-themed cyberpunk UI
• No API key storage on backend - users bring their own

Tests: cd backend && pytest Linting: cd frontend && npm run lint
