🔧 Variations Overview

Variation 1: FastAPI + AWS Bedrock (Recommended for AWS Users)

• Best for: Production AWS environments
• Pros: Serverless-ready, multiple models, AWS integration
• Cons: Requires AWS account and credentials
• Cost: Pay per use (AWS Bedrock pricing)

Variation 2: Flask + OpenAI API

• Best for: Rapid prototyping, familiar stack
• Pros: Simple, well-documented, GPT-4 access
• Cons: Requires OpenAI API key
• Cost: Pay per use (OpenAI pricing)

Variation 3: Node.js + Anthropic API

• Best for: JavaScript developers, Claude access
• Pros: Full JavaScript stack, Claude 3 models
• Cons: Requires Anthropic API key
• Cost: Pay per use (Anthropic pricing)

Variation 4: FastAPI + Ollama (Recommended for Local/Free)

• Best for: Privacy, no API costs, offline use
• Pros: Completely free, runs locally, no API keys
• Cons: Requires local GPU/CPU resources
• Cost: Free (hardware only)

🚀 Quick Start

Choose your variation and follow its specific README:

# Example: Variation 1 (FastAPI + Bedrock)
cd variation-1-fastapi-bedrock
cat README.md
cat SETUP.md

📚 Documentation Files

Each variation includes:

• README.md: Overview and features
• SETUP.md: Step-by-step setup instructions
• ARCHITECTURE.md: Technical architecture details
• Code comments: Inline explanations throughout

🧪 Testing

Each variation includes:

• Unit tests for backend logic
• Integration tests for API endpoints
• Frontend validation tests
• End-to-end testing instructions

🔒 Security Notes

• Never commit .env files with real credentials
• Use environment variables for all secrets
• Each variation includes security best practices
• CORS is configured for local development (adjust for production)

📖 Learning Path

1. Start with ARCHITECTURE.md (root level) to understand the overall design
2. Read COMPARISON.md to choose your variation
3. Pick a variation and read its SETUP.md
4. Study the code comments in the backend and frontend
5. Experiment with modifications

🛠️ Customization

All variations are designed for easy modification:

• Clear separation of concerns
• Modular architecture
• Extensive comments
• Configuration via environment variables
• Easy to swap LLM providers
