Pros
Pro Flexible
Being a small one file distribution it includes almost every vital thing you need to support little websites (routing, templating). Everything else can be implemented using plugins.
Pro Single-file distribution
Bottle works around the one-file approach, everything is done in a bottle.py
file. This means that it's extremely easy to share and upload your application since it practically is just one python file.
Pro No need to install
It is so little there's no need to install, it is included in the standard libs python.
Pro Async, *let friendly
Using it with gevent is a breeze. It's a WSGI app so it's easy to make it work with anything.
Pro Truly magnificent
Pro Easy To Use
Rocket makes extensive use of Rust's code generation tools to provide a clean API.
Pro Streams
Rocket streams all incoming and outgoing data, so size isn't a concern.
Pro Cookies
View, add, or remove cookies, with or without encryption, without hassle.
Pro Testing Library
Unit test your applications with ease using the built-in testing library.

Pro Boilerplate Free
Spend your time writing code that really matters, and let Rocket generate the rest.
Pro Config Environments
Configure your application your way for development, staging, and production.
Cons
Con Small community. Difficult to find online docs and examples
Con Very hard to develop projects that are not smaller than 1000 lines
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.
Con Abandoned
Con Nightly
Uses only nightly versions of Rust.
