TL;DR

Turns out Hexagonal, Clean, and Onion architectures aren’t some mystical new shapes—they’re all just riffs on the same idea: keep your core logic insulated from change. By partitioning your code into layers (or “circles,” if you insist), you limit the blast radius when a database, UI framework, or external API decides to break your day.

At the end of the day it’s not about drawing perfect hexagons or onions on a whiteboard—it’s about stability. All three patterns teach you how to manage coupling so that slow-moving business rules stay rock solid, no matter how wild the outside world gets.
