A [common criticism](http://news.ycombinator.com/item?id=3737272) of building applications outside of Rails is the loss of a great, integrated tool chain.

> You don't pick Rails as the engine for powering your API simply for the asset pipeline, you pick it for all the other stuff @macaw pointed out! If you hook up Sinatra and Sprockets, you are without Rails' ORM, migrations, generators, routing, test infrastructure, plugin ecosystem, and arguably most importantly, the conventions and agility.

There is some truth to that, but it doesn't have to be that way.

I'm going to pick on ActiveRecord. The internet is [littered](http://community.active.com/blogs/productdev/2011/02/28/using-activerecord-3-without-rails) [with](http://exposinggotchas.blogspot.com/2011/02/activerecord-migrations-without-rails.html) [posts](https://github.com/thuss/standalone-migrations) about using ActiveRecord outside of Rails. Most solutions involve hacking together a Rake file that deals with this stuff. Its a pain.
