klein - werkzeug + twisted.web

•    Python

Klein is a micro-framework for developing production-ready web services with Python. It is 'micro' in that it has an incredibly small API similar to Bottle and Flask. It is not 'micro' in that it depends on things outside the standard library. This is primarily because it is built on widely used and well tested components like Werkzeug and Twisted. A Klein bottle is an example of a non-orientable surface, and a glass Klein bottle looks like a twisted bottle or twisted flask. This, of course, made it too good of a pun to pass up.

Camping - the 4k pocket full-of-gags web Micro framework

•    Ruby

Camping is a web framework which consistently stays at less than 4kB of code. You can probably view the complete source code on a single page. But, you know, it's so small that, if you think about it, what can it really do? The idea here is to store a complete fledgling web application in a single file like many small CGIs. But to organize it as a Model-View-Controller application like Rails does. You can then easily move it to Rails once you've got it going.
