I've built (and continue to) a lot of companies using Rails. I also do Swift on iOS and have been playing around with Swift on the server since last year. I have some friends that have an idea and I'm going to help them build it. So what do I use? The fast, low memory footprint of Swift? No. I use Rails. I use bootstrap. I don't make a JS only frontend with api backend (Turbolinks works fine). I use what makes me productive and what's gets the first rev out the quickest. For hosting, I put it on my Mac Mini (in my living room) via VirtualBox, with the same Nginx proxy I use for all my projects. I have no problems with scaling because I don't need to. Cross that bridge IF I get there. I went through a number of years trying the latest and greatest frameworks, aws configs, etc. None it mattered to my projects. It did help with day jobs, but that was it. Some other poster here was right when he said tech is about 10% of your business. There is so much other stuff outside of building your app/site and having analysis paralysis is gonna stop you dead in your tracks. My advice (as many on HN have said before): go with what you know, don't over engineer, ship early and often.
