I wrote a pricing comparison guide at https://fly.io/docs/rails/getting-started/migrate-from-heroku/#pricing https://fly.io/docs/rails/getting-started/migrate-from-herok... What’s important is that pricing isn’t the same and the free plan is really a way for you to try Fly before deciding to dial up the resources. You can use it for really small apps, but trying to squeeze a Rails app into 256Mb RAM on 3 servers is tough. I moved few of my Heroku apps over to Fly and pay about half much for about 4x what I was getting on Heroku. When v2 of the Fly app platform goes out, I expect that price to go down even more since apps can sleep when they’re not serving up requests.
