Ask HN: Framework with the most built in functionality?

Hi everyone. I'm about to start a new web development project and I want to move fast. I'm looking for recommendations on a web development framework that has the most functionality built in, so I won't have to reinvent the wheel. Specifically, it would be great if there's a framework that makes it very easy to have user accounts that let a user manage their account details (email, username, password) and that provides password recovery. Also do any frameworks have payment/subscription management modules available? Or if there are add-ons to a framework that provide this kind of thing I'd like to know. I'm open to any programming language/platform though I prefer Java and Python. Thanks!
