Hexagonal vs Clean vs Onion Architecture... It Doesn’t Matter

Whether you call it Hexagonal, Clean, or Onion, it all boils down to one goal: managing coupling so your core logic stays rock-solid when external pieces change. These patterns aren’t about fancy diagrams or buzzwords—they’re about setting clear boundaries (layers, ports, adapters) that control the blast radius of any change.

At their heart, each architecture teaches the same lesson: keep your business rules insulated from volatility. Pick circles, hexagons, or onions—whatever helps you decouple and maintain stability in the face of shifting databases, UIs, or third-party services.
