Flask is very easy to get up and going, with vanilla HTML or with bootstrap pieces. It doesn't take much lines of python to load Flask to get headers working, etc, and since it's all modular you don't have to have something you don't want in your application. Each module within Flask works very well, and is extremely good on bandwidth and CPU usage. See More
Setting up a large project with Flask is not that easy considering how there's no "official" way of doing it. Blueprints are a useful tool in this regard but require some additional reading and are a bit tricky to get right for a beginner. The lack of some defaults can also be problematic. Having to choose between different libraries for a certain task is never easy, especially if you have never worked with Flask before. See More
The choice of not having an ORM, but instead choosing one suited to the task, gives developers who use Flask a great deal of flexibility. Another area where Flask gives a lot of options to developers is the templating. They can use Jinja2, Flask's default templating language or choose from a number of different templating languages they desire. See More
Minimal frameworks usually give the developer a lot of space and flexibility. But with that comes the responsibility of having to code every part of the application yourself, if you get stuck somewhere you are on your own usually. Fortunately, this is not the case for Flask. Because it's very popular and as a relatively large following there are a lot of third-party libraries and plugins available for it. So if you want to save time or if you don't know how to solve a particular problem chances are that someone has already made a library for that. See More
Flask is one of the most popular Python web frameworks, if not the most popular one. As such, there's plenty of guides, tutorials, and libraries available for it. A large number of important Python libraries, such as SQLAlchemy have libraries for Flask, which add valuable bindings to make the development process and the integration between these libraries and Flask as easy as possible. See More
Even though it's pretty minimalistic out of the box, Flask still provides the necessary tools to build a quick prototype for a web app right after a fresh install. With all the main components pretty much packed in the flask package, building a simple web app in a single Python file is as easy as it gets. See More
While Bottle is a great framework for building small applications (generally less than 1000 lines of code), it starts getting very hard to manage your application if you want to go even a bit larger than that. The fact that it follows a single-file distribution model and that it's missing something like Flask's blueprints only make this problem worse. See More
I have migrated my flask application to Falcon in 3hours. Performance improves a lot. See More
Because it's basically a framework for building real-time applications it has great support for things like WebScokets and uses non-blocking I/O. But it lacks in features that are used to build general-purpose websites like blogs, e-commerce sites, web portals etc... For example it lacks ORM integration (at least out of the box) and it doesn't have a very powerful template engine. See More
Talking to database is a pretty common thing for a web application to do. Larger frameworks know this, and cover it in some detail by the end of the tutorial. In contrast, the Klein documentation is currently silent on this topic, leaving the issue of how to do database queries in a way that won't block your event-driven code entirely up to you. See More
The fact that a Klein server is event-driven and non-blocking means that it can start handling a new request while previous requests are still open. This lets you serve more requests from a single process, meaning running multiple servers is now an option to be explored when your site makes it big, rather than a necessity for responsiveness under even modest loads. Multiple requests per process also gives you flexibility to do things that would be impractical in WSGI-based alternatives like Flask or Bottle, such as keeping a connection to the browser open to send it chat messages or game updates in a Server Sent Event stream.
