Tornado is a scalable, non-blocking web server and web application framework written in Python.[2] It was developed for use by FriendFeed; the company was acquired by Facebook in 2009 and Tornado was open-sourced soon after.[3]


Tornado is noted for its high performance. Its design enables handling a large number of concurrent connections (i.e., tries to solve the "C10k problem").


  • An asynchronous MongoDB driver called Motor.
  • CouchDB drivers called corduroy and trombi.
  • Asynchronous driver for PostgreSQL wrapping psycopg called Momoko
