I built FormAPI [1] with Ruby on Rails. I used plain Rails views for most of the CRUD things, and used React/Redux to build the template editor [2], which is pretty complex. I've been extremely productive with Rails, and the performance has not been an issue at all. My plan is to rewrite the API and workers in Elixir when it will save me $2,000 per month on hosting costs. And even then, I would probably be making so much money that it wouldn't matter. I started on Heroku, but I had a lot of free AWS credits from Stripe Atlas that I wanted to use. So I moved to Convox [3] on AWS, and it has been absolutely awesome. I have a rock-solid cluster across 3 different availability zones, and I'm also running Postgres with high availability (RDS). I haven't had a single second of downtime since I migrated [4] (I up the status dashboard a few months ago, but moved to AWS earlier than that.) Convox supports auto-scaling and rolling deploys. It waits for the web process to be healthy, and if something crashes it rolls back the deploy without any downtime. I can also terminate any instance at will, and another one will pop up to replace it with zero downtime. After using it for the last ~6 months, I feel confident enough to start offering a 99.999% SLA.
