Django: Python application framework

Learn what Django provides for Python web applications, including authentication and content administration, and how to plan a maintainable production service.

Updated 8 September 2026

What Django is used for

Django is an open-source Python web framework. It includes facilities for common application tasks such as user authentication, content administration, sitemaps and feeds. Teams use it to build application-specific behaviour on a consistent foundation.

A research portal, for example, might need structured records, controlled editing and public search pages. Django can provide the framework, while the project defines the data and who is allowed to change it.

Administration and application behaviour

Built-in administration can help a team work with its application data, but it is not automatically the right interface for every customer workflow. A public search page and an internal data-management screen have different usability requirements.

Django includes protections against several common web security mistakes. Application-specific authorization still needs to be implemented correctly, especially when users can access records belonging to different organizations.

Planning a Django service

Design the deployment around the database, media storage and any background work the application requires. The framework does not determine which hosting provider or public proxy a project uses.

For a data-heavy page, measure the queries and processing needed to produce a response. Adding a CDN may help reusable assets but will not automatically fix inefficient work on a private, dynamically generated endpoint.

How DNSTrace.dev detects Django

Detection reads the final HTTPS response and the first bytes of its markup. One matching signal is reported as strong evidence; two or more independent signals are reported as confirmed.

csrftoken cookie — Django's default cross-site request forgery cookie name.
sessionid cookie — The default session cookie, supporting evidence when it appears alongside csrftoken.
server naming Gunicorn — A common Django application server, reported separately as the runtime rather than the framework.

What a detection proves

The response was produced by a Django application.

What it does not prove

The Django version, the Python version or the hosting platform. The cookie name is configurable, so a hardened deployment can hide it.

Common questions about Django

Does Django provide user accounts?

Django includes a user authentication system. A project still needs to define its own permissions, account lifecycle and rules for access to application data.

Does a csrftoken cookie always mean Django?

It is the Django default and rare elsewhere, so DNSTrace.dev treats it as strong evidence. A single cookie match is reported as strong rather than confirmed for exactly this reason.

Is Gunicorn part of Django?

No. Gunicorn is a Python application server frequently used to run Django, and DNSTrace.dev reports it as its own runtime signal.
