So my question would be, what&#x27;s the difference between Rails and other frameworks, especially since we are doing RESTful APIs from the start?<p>It would seem to me that Rails is just not the tool to use going forward for writing APIs for websites at scale.  There are much better tools out there.<p>Rails&#x27; sweet spot is server side rendered pages that are quick to bring up and to add features.  It seems great for certain types of websites so it does have its niche.<p>But moving forward, Rails for API vs. other frameworks in other languages is really a wash in terms of productivity, while other frameworks in those other languages are much more highly performant.
