The project is split into four independent modules:

AI Engine
AI Models
DevOps

• Node.js ≥ 18 & npm ≥ 9
• Python ≥ 3.10 & pip
• Git
• A free Groq API Key

1. Go to console.groq.com/keys and sign in (or create a free account).
2. Click Create API Key, give it a name (e.g., reposage), and copy the key.
3. The key is used by both the Backend (via GROQ_API_KEY env var in backend/.env) and the Frontend (via VITE_GROQ_API_KEY). See the backend setup below.

git clone https://github.com/kalyan-1845/ai-code-reviewer.git
cd ai-code-reviewer

cd backend
npm install
cp .env.example .env    # Add your GROQ_API_KEY
npm run dev              # Starts on http://localhost:5000

cd ai-engine
pip install -r requirements.txt
uvicorn app:app --reload  # Starts on http://localhost:8000

cd frontend
npm install
npm run dev              # Starts on http://localhost:3000
