We use it on a large monolithic application. It’s too brittle. It abstracts away the benefits of the underlying database all for the ability to support a handful of databases? Meh. The default queries or mode of constructing queries is so generic that it makes no sense to use: I miss the scalpel that is crafting my own SQL queries taking into account indexes and such running and tuning queries before committing them to code.

Look I was being hyperbolic but SQLAlchemy is great for prototyping but it’s then it’s too easy to just keep building on that crutch.
