If the application is simple such as less endpoint or simple logic, I'd suggest Flask. But what you're building is quite a large system that contains many logics and a lot of models. So I'd suggest you with Django and Django REST framework. Django ORM is also one of the best ORM in the world as well.

FastAPI is modern microframework. If you haven't used any of them, I'd suggest FastAPI. Django REST is also good if you have previous experience with it.

If you want to be a Web developer with knowledge in another frontend and NoSql technology, maybe continue with Flask. However, if you want to create very fast solutions to grow up with a new business and merge these with data analysis and other tools, Django is the answer. Basically read more about the service architecture where you feel more comfortable, Microservice or Monolithic, but please will not married with any because they solve issues to different contexts.

Bottle is much less bloated and fast. Its built-in templating system is one of the fastest as it compiles the templates in bytecode. Also Bottle has no depenencies, preventing dependency bloat.

For starters flask provides a beautiful and easy way to create REST APIs. Also its supported by excellent beginner docs as well as a very active community. Another good thing with Flask is its widely available list of plugins which allow you to build as you go. Its also good in performance and can scale to a quite decent level. However, if you are sure your project is going to be fairly big, it would be better to start with Django as it provides a lot of features out of the box and is extremely stable in performance. Both these frameworks have support for Swagger, JWT, Coverage Report although you have to install plugins for them. Deploying both of these are fairly simple and there is huge documentation available. Django has one of the best documentations I have come across. I hope I was able to answer your queries.

It has the necessary packages for what you need, in addition to optimizing your time with what is needed.

Node.js is great but if I had a choice for something like this I would pick Elixir and Phoenix. They have LiveViews and channels which be one step up then the other 3 plateforms. It will also scale better and respond faster. Last will probably far less code as well.

Node.js is the perfect tech to real-time features like chats, forums, quizzes and polls. Additionally it has great support for objects storage like Mongodb and its important for file media management.

I would suggest you to pick the right stack for the right purpose. My suggestion would be to go for Microservices approach and break your app into smaller pieces according to the type of functionality like you mentioned above. E.g if you would be expecting the high traffic on you platform, then Node.js can be used as the endpoint there to handle that traffic. Normal form processing can be done in Laravel but I would not suggest codeigniter as managing code is difficult there.

So this way you can decide do architecture you app and can use the best of the feature from all the languages. Even it would be easier for you to manage your app based on the functionality and team who will be working on that. Hope you would like my suggestions.
