haskell - What are free monads? - Stack Overflow
https://stackoverflow.com/questions/13352205/what-are-free-monads
A free monad stores a list of functors instead of a list of values. Technically, you could implement free monads using a different data type, but any implementation should be isomorphic to the above one.

https://typelevel.org/cats/datatypes/freemonad.html
A free monad is a construction which allows you to build a monad from any Functor. (In Cats, the type representing a free monad is abbreviated as Free[_].) Using Free Monads.

Free monads are useful for many tree-like structures and domain specific languages. Cofree comonads are dual to free monads. They provide convenient ways to talk about branching streams...
Free Monads Explained (pt 1). Building composable DSLs | Medium
https://medium.com/@olxc/free-monads-explained-pt-1-a5c45fbdac30
🤔 Free monad? The core idea of Free is to switch from effectful functions (that might be impure) to plain data structures that represents our domain logic. Those data structures are composed in a...
Free Monads Are Simple - Underscore
https://underscore.io/blog/posts/2015/04/14/free-monads-are-simple.html
The free monad brings together two concepts, monads and interpreters, allowing the creation of composable monadic interpreters. That's a bunch of big words, but why should we care?
free monad in nLab

A free monad is a free object relative to a forgetful functor whose domain is a category of monads. This general concept has many different specific incarnations, since there are potentially many...
Free monads - what? and why?

Monads themselves are scary enough, but free monads!? Luckily as usual things are much simpler then they might sound. As the title suggests, we know that the answer to our problems is a Free...
Monad (functional programming) - Wikipedia
https://en.wikipedia.org/wiki/Monad_(functional_programming)
In functional programming, a monad is an abstraction that allows structuring programs generically. Supporting languages may use monads to abstract away boilerplate code needed by the program logic. Monads achieve this by providing their own data type (a particular type for each type of monad)...

Free Monads are a really powerful tool. One of the reasons is composition. Our example is rather simple, but you can imagine that you've built a whole instruction set for your business logic.

functional programming - What is the "Free Monad + Interpreter..."
https://softwareengineering.stackexchange.com/questions/242795/what-is-the-free-monad-interpreter-pattern
The free monad part is just a handy way to get an AST that you can assemble using Haskell's standard monad facilities (like do-notation) without having to write lots of custom code.
For-Comprehension Free Monads in Scala - DZone Java
https://dzone.com/articles/fully-for-comprehansion-able-free-monad-in-scala
A free monad is a construction that allows you to build a monad from any functor. There exists rich literature that explains this concept, notably from Cats and Scalaz documents.
