Django is a web application framework written in Python.

Django follows the “batteries included” approach, which means it ships with a lot of built-in features for building database-backed web applications.

The main parts of a Django application are:

  • Models, which define database-backed data structures
  • Views, which handle requests and return responses
  • Templates, which render HTML
  • URLs, which map paths to views
  • Admin, which gives you a built-in management interface

Django is often used with:

  • PostgreSQL or another relational database
  • The Django ORM for database access
  • Django templates for server-rendered HTML
  • Django admin for managing application data
  • Django REST Framework when building APIs

Why people use it

Django is a good fit when you want a full-featured web framework with strong defaults, clear conventions, and built-in tooling.

It is especially strong for:

  • CRUD applications
  • Internal dashboards
  • Content-heavy sites
  • Applications that benefit from a ready-made admin interface

Tradeoffs

Django can feel heavier than smaller frameworks if you only need a tiny API, but it saves time when you want the framework to provide most of the common plumbing.

Rule of thumb:

  • Use Django when you want a full web framework with strong built-in defaults
  • Use a lighter framework when you only need a small service or minimal API
