Quick Decision Tree

• REST API? → FastAPI
• Full web app? → Django
• Learning/Prototyping? → Flask
• Max performance? → Falcon
• Real-time? → Sanic/FastAPI

Framework Comparison

Django

✓ Built-in: Admin, ORM, Auth, Security.

✓ Best for: Large apps, CMS, E-commerce.

✓ Performance: Up to 8,000–10,000 req/sec.

✗ Can be overkill for simple APIs

Flask

✓ Minimal, easy to learn.

✓ Best for: Small-medium projects.

✓ Performance: Up to 10,000 req/sec.

✗ Needs extensions for features

FastAPI - The Modern Solution

✓ Async, auto-docs, type hints.

✓ Best for: Modern APIs, microservices.

✓ Performance: Up to 20,000 req/sec.

✗ Requires Python 3.6+

⚡⚡⚡ Performance Frameworks

Falcon

• Ultra-minimal REST APIs.

• 4,000–11,000 req/sec.

• Bare-bones by design.

Sanic

• Async with Flask-like API.

• 10,000–16,000 req/sec.

• WebSocket support.

💡💡💡 Real Scenarios

• E-commerce site → Django Why: User auth, admin panel ready

• ML Model API → FastAPI Why: Async, validation, auto-docs

• Blog/Portfolio → Flask Why: Simple, flexible, easy deploy

• Chat App → Sanic/FastAPI Why: WebSocket, high concurrency

⚠️⚠️⚠️ Common Mistakes

• Choosing by benchmarks alone
• Using Django for simple APIs
• Flask for large apps without structure
• Ignoring team expertise

🎯🎯🎯 Decision Factors

➀ Team Experience

• New to web dev? Flask
• Need structure? Django
• Know async? FastAPI

➁ Project Timeline

• Tight deadline? Django
• Time to learn? Any framework
• MVP needed? Flask/FastAPI

➂ Maintenance

• Long-term project? Django
• Microservices? FastAPI
• Quick prototype? Flask
