When not to use hexagonal architecture?

Skip it for CRUD apps, early exploration, single adapters, or perf-critical paths — flat structures ship faster without the tax.

What are hexagonal architecture trade-offs?

Upfront complexity (5x files for changes), indirection (harder debugging), rigidity (port churn) — versus domain isolation and easy testing.

Yes for complex, stable domains with real logic. No for simple data apps — it adds overhead without payoff.

Flat CRUD app meets hexagonal architecture. Result? Changing one field name hits six files. You've optimized for nothing.
