Most MVPs don’t fail because of missing features.

They fail because building them takes too long.

The MVP backend trap

Early MVPs often involve:

  • Over-designed schemas
  • Premature auth decisions
  • Infra choices that don’t matter yet
  • Backend work that gets rewritten anyway

All before you’ve validated the idea.

What an MVP actually needs

For most products, the first version needs:

  • CRUD endpoints
  • Users
  • Authentication
  • Persistence
  • Some visibility into errors

That’s it.

A different approach

Instead of building a backend:

  • Define your data model
  • Call real endpoints from the frontend
  • Use session tokens for per-user data
  • Log requests automatically
  • Upgrade only when needed

This is exactly how ReqRes is designed.

From UI to working app

You can go from UI prototype → real app in minutes.

The Notes example app shows a production-style flow without backend code.

What happens later?

When your MVP proves itself:

  • Increase limits
  • Add automations
  • Enable longer log retention
  • Keep the same API calls

No migrations. No rewrites.

Final thought

MVPs should validate ideas-not lock you into architecture.

If you’re building frontend-first, your backend should be too.
