Cyclops is a functional programming library for Java 8+ providing advanced purely functional data structures, monads, monad transformers, and reactive streams integration. It offers an easy-to-use API for functional and asynchronous application development on the JVM.

Use cases

  • write functional code in Java
  • use monads like Option, Either, and Try in Java
  • work with immutable persistent collections
  • process streams reactively and asynchronously
  • avoid nulls and exceptions with functional error handling
  • lazy evaluation with Eval
  • structural pattern matching in Java

When to choose

  • you want functional programming abstractions on the JVM
  • you need type-safe alternatives to Optional and exceptions
  • you want reactive streams with functional data structures

When to avoid

  • you are on a modern Java codebase already using standard streams and records
  • you prefer lightweight single-purpose libraries
  • you need a library under very active development
