Haddock on Heroku is a super-simple Sinatra-based web frontend for Haddock, a Ruby library for generating memorable passwords. As the name implies, it's hosted on Heroku, and it uses the "2of12" English word list from the 12dicts project.

Haddock on Heroku is designed to be used securely from anywhere, on any device. All connections are SSL-encrypted to prevent eavesdropping (e.g. on unsecured wi-fi), and the compact interface fits neatly on most smartphone screens, automatically scaling to fit the screen width.
