I realise the old adage is use what you know, but sometimes it's worth picking something new up. I was wondering what people would currently reach for today as a "batteries included" framework that lets you get to building as fast as possible, but keeping an eye on how it might grow.

I've heard rails is getting a bit too unwieldy, the js world is focused on front end and Laravel is growing for smaller SASS solutions.

Are there any areas outside of the JS/Ruby/Python worlds that we should be looking at here? Is Server Side Swift ready yet?
