Tornado vs webapp2: What are the differences?
Developers describe Tornado as "A Python web framework and asynchronous networking library, originally developed at FriendFeed". By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. On the other hand, webapp2 is detailed as "Lightweight Python web framework compatible with Google App Engine’s webapp". webapp2 is a simple. it follows the simplicity of webapp, but improves it in some ways: it adds better URI routing and exception handling, a full featured response object and a more flexible dispatching mechanism.
Tornado and webapp2 can be categorized as "Frameworks (Full Stack)" tools.
Tornado is an open source tool with 17.9K GitHub stars and 4.97K GitHub forks. Here's a link to Tornado's open source repository on GitHub.

Around the time of their Series A, Pinterest’s stack included Python and Django, with Tornado and Node.js as web servers. Memcached / Membase and Redis handled caching, with RabbitMQ handling queueing. Nginx, HAproxy and Varnish managed static-delivery and load-balancing, with persistent data storage handled by MySQL.
SpreadServe's RealTimeWebServer is built in Tornado. Spreadsheets loaded into SpreadServeEngine instances are projected into browsers using Tornado. Server side recalcs are pushed to the browser using web sockets.
setup an api for a client with tornado backend. incredibly fast and lightweight. unfortunately breaks down when using third party libraries which block internally.
