I was just looking at your pricing. :) All in all Netlify does offer a compelling service for this scope. I'm also interested in the Pro tier being free for OSS, that's fantastic!

To be fair, setting up AWS for the first time is a real PITA and I happen to have had it all set up (IAM, buckets, command line, etc) already, so my barrier to entry was low. Had I known of Netlify when I first moved my site to AWS I probably would have gone with Netlify for the convenience and free HTTPS cert.
