Is Django good for big projects?

Django is well established, mature and has a very large ecosystem of third party libraries and out of the box features that really make the development easy and fast . You really don’t want to write all the glue code for ORM, database, task runner, authentication, admin etc. The biggest strength around Django is python.

Instagram currently features the world’s largest deployment of the Django web framework , which is written entirely in Python.

Django might help in some specific use-cases, but it might not be wise to develop everything with Django (or any other framework alone). You need to build a very basic app, which does not require database, file operations, or anything even remotely complex. Micro frameworks are better suited for these use-cases.
