Clean vs Onion vs Hex: Which Architecture Actually Works?
Every dev has said it: “It’s just a simple CRUD app.” Six months later, you’re staring at a spaghetti monster — brittle tests, tangled dependencies, and changes that cost blood, sweat, and sanity. That’s when architecture stops being academic and starts being survival.
In this video, we compare Clean Architecture, Onion Architecture, and Hexagonal Architecture — and show you when each one makes sense:
Clean → Uncle Bob’s cathedral of concentric rings. Strict, powerful, but heavy.
Onion → Clean’s pragmatic cousin. Structured, less ceremony, easier day-to-day.
Hexagonal → Think sockets & plugs. Core logic in the middle, adapters on the edge. Swap Stripe for PayPal? Swap the plug.
How to choose:
Tiny MVP? Don’t cosplay Clean. Keep it simple.
Enterprise, compliance-heavy, or multi-team? Clean/Onion for guardrails.
Most everyday apps with integrations? Hex is the pragmatic sweet spot.
👉 Bottom line: Clean gives you rules. Onion gives you structure. Hex gives you flexibility. The right choice isn’t about looking smart in a diagram — it’s about making tomorrow’s changes cheaper.
