When comparing N2O vs Bottle, the Slant community recommends Bottle for most people. In the question“What are the best backend web frameworks?” Bottle is ranked 20th while N2O is ranked 29th. The most important reason people chose Bottle is:
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.

Pros
Pro Fast binary data
Pro Binary encoding and protocols
Here is a list of types of endpoints which are supported by EMQ and accesible to N2O apps: WebSockets, MQTT, MQTT-SN, TCP, UDP, CoAP. Normal use of N2O as a Web Framework or a Web Application Server is through WebSockets, but for IoT and MQTT applications it could be served through UDP or SCTP protocols providing application level message delivery consistency.
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
Cons
Con Unfriendly developer community
Developers are often rude and unfriendly to users.
Con Bad documentation
It has bad documentation, which leaves out crucial steps, making it hard to learn.
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.
