It's great to see folks building frameworks on top of frameworks. I've started to look into full stack starter-kit frameworks that goes beyond the admin panel and here's what's out there these days.

* https://bullettrain.co - Opensource, $0/year

* https://jumpstartrails.com - Opencore, $249/year

* https://www.bootrails.com - Closed source, ~$83/year

I've even started to piece on together for my own projects at https://github.com/rocketshipio/monolith, which will be open source, $0, and MIT licensed.

Some of the libraries I'm noticing that seem "settled" include:

* Devise for authentication

* Pundit for authorization

I started to piece on together for my own projects at https://github.com/rocketshipio/monolith, which will be open source, $0, and MIT licensed.

I'm hoping enough people converge around any one of these products where we end up with something as high quality as Rails. If the community agrees on how users, authorization, subscriptions, etc. should be modeled, it opens up the door for a set of APIs and plugins that will make creating SaaS products even easier.

My thinking on the economics of this is the Opencore stuff will be a race to the bottom in terms of pricing towards free or a nominal fee (I guess $250/year is that). What will end up costing money is tech support. I do see an ecosystem of third-party services that integrate with SaaS kits emerging, such as rapid ways to deploy, analytics services, etc.
