I like the sinatra framework, but might have to work in python. A quick web search has uncovered a few python equivalents including itty, flask and juno.
I'd like to know people's experience of these, or other sinatra equivalents. Which would you recommend?
Okay. So I'm biased because I'm the author of Flask, but here something to help you make the pick:
Besides the ones you mentioned there is also Bottle which is similar to Flask but more minimalistic. Unlike Flask it also re-implements everything from ground up instead of building on an independent foundation like Werkzeug.
Other alternatives is web.py, one of the first microframeworks ever. Same rule as bottle: re-implements everything from the ground up.
