Rails is optimized for small teams to ship code to multiple platforms. When I visit indiehackers and see people posting about their struggles creating a page to update user profiles and the associated back end code - it's not hard to see why it's more productive. There is very little in the way of boilerplate or BS.
There is nothing out there that has anything close to the productivity of rails. Not that there can't be; it's just not a mindset/approach the industry has embraced.
