Where can I find up-to-date django applications?

Question

Django

Greetings, I implemented a small educational project similar to a toaster. Wanted to add messages between users. I think it is not appropriate to create your own application for this and it is better to use a ready-made solution. I found "postman" but don't know if it's up to date.
Please tell me what tools this is implemented in real projects and where it is better to look for ready-made applications.

Answer 1

The very first place: www.djangopackages.com
Here you can see collections by "subject".
For example, your query about messengers: https://www.djangopackages.com/grids/g/messaging/
Second place is PyPi .
