Get in Touch

Django and FastAPI are the two titans of Python web development. Django has been battle-tested for 20 years. FastAPI is the new hotness with superior performance. Which should you choose?

Django: The Full-Stack Workhorse

Django is a batteries-included framework. It gives you ORM, auth, admin panel, migrations, and more out of the box. You can scaffold a fully functional CRUD app in hours.

  • Built-in admin panel (saves weeks of UI work)
  • Mature ecosystem and third-party packages
  • Excellent documentation and community
  • Django ORM is powerful but opinions feel strong

FastAPI: The High-Performance Newcomer

FastAPI is explicitly designed for building APIs. It's built on async/await, handles automatic validation with Pydantic, and generates OpenAPI docs automatically.

FastAPI's async-first design makes it significantly faster than Django for I/O-bound operations — often 2-3x faster in benchmarks.

Performance Comparison

  • FastAPI: ~12,000 requests/sec (async)
  • Django: ~3,500 requests/sec (ASGI)
  • Winner: FastAPI for raw throughput
