Flask is designed to be extended and modified in a couple of different
ways:
- Flask extensions. For a lot of reusable functionality you can create
extensions. For extensions a number of hooks exist throughout Flask
with signals and callback functions.
- Subclassing. The majority of functionality can be changed by creating
a new subclass of the :class:`~flask.Flask` class and overriding
some methods.

- Forking. If nothing else works out you can just take the Flask
codebase at a given point and copy/paste it into your application

The downside of forking is of course that Flask extensions will most
likely break because the new framework has a different import name and
because of that forking should be the last resort.

the very last resort.
Scaling like a Pro

There is only one limiting factor regarding scaling in Flask which are
the context local proxies. They depend on context which in Flask is
defined as being either a thread or a greenlet. Separate processes are
fine as well. If your server uses some kind of concurrency that is not
based on threads or greenlets, Flask will no longer be able to support
these global proxies. However the majority of servers are using either
threads, greenlets or separate processes to achieve concurrency which are
all methods well supported by the underlying Werkzeug library.

Dialogue with the Community
---------------------------
The Flask developers are very interested to keep everybody happy, so as
soon as you find an obstacle in your way, caused by Flask, don't hesitate
to contact the developers on the mailinglist or IRC channel. The best way
for the Flask and Flask-extension developers to improve it for larger
applications is getting feedback from users.
