I haven't used Flask (or Python) aside from one small hack project. It seemed simple and straight forward enough, and very similar to Ruby's Sinatra framework. Personally in Ruby I would most likely pick Sinatra, in Python I'd pick Flash or something similar.

However if you wanna play with languages you're less familiar with, I'd recommend Go, or Node.js.

Personally I find Go really interesting as it's quite different from the languages I normally work in, and it's concurrency model makes it performant without being a mindfuck.

Node.js is interesting as it's Javascript, but extremely I/O performant due to it's evented nature, but that also makes concurrency a bit of a mindfuck at times.

Those are my suggestions at least if you're itching to get your toes wet in some new fun languages :)

I actually went through the Golang quickstart before writing my original post. It is very tempting, but I'm concerned it might be a long journey for what should be a simple app. In your experience, how productive is Go at kicking out basic CRUD APIs?

I haven't built a full CRUD app myself, mostly some small hacked together tools and various silly stuff. Personally though I did end up just experimenting with basic stuff to get familiar with the language and tools for a couple of evenings before I got anything even half-useful done.

So I'd say, if just want to get a simple CRUD API app out quickly, use Python and Flask or something similar as it's something you already know well. If you wanna use the CRUD API app as an excuse to play with new languages and technologies which will hopefully lead to a expanded skill-set, then go for Go ;)

As for Node.js, if you already know Javascript, it'll fall about 30-40% of the way between using Python that you know and Go that you don't know.
