The Hexagon toolkit is meant to provide abstraction from underlying technologies (data storage, HTTP server engines, etc.) to be able to change them with minimum impact.

Hexagon's high-level features.
Simple to Use: Hexagon is focused in allowing you to use the features you use the most in your daily coding in the easiest way.
Easy to Hack: The libraries are done to be lean and simple so you can tweak it to suit your needs instead relying on third parties.
Pluggable Adapters: Adding an adapter is just implementing the port's interface. You can code your own adapters from scratch or tune the existing ones.
Kotlin First: The library is coded in Kotlin for coding with Kotlin. No strings attached to Java (as a Language).
Modular: Each feature is isolated in its own module. Use only the modules you need without unneeded dependencies.
