I'm a fan of Spring Boot + Thymeleaf + Htmx. Django is a proven platform for the kind of app you want to build so you likely will be fine either way.

It doesn't matter. Choosing a framework is not actual work. When you are not building, neither has advantages, and you are not building.

Sure, maybe one or the other might make the work marginally easier. But it is going to be hard work no matter what...if you build of course. Not building is the easiest path by far, and there is nothing wrong with not building.

The app idea is a social networking application so it would need users, likes, comments, messaging and an activity stream/news feed.

The hard part of building a social networking app is getting a bunch of people interested in doing those things with it. They don't care about your technology. And they damn sure don't care about how easy or hard it was for you to build.

Good luck.

The documentation for Django has consistently been cited in this forum as an excellent example of thoroughness and best practices.

Django is going to get you up and running and in business, while springboot is much harder to deploy.
