What should you choose?
Fullstack or a decoupled approach which is basically seprate frontend and backend.
Choosing your app architecture depends on your specific goal -
Option A - Separate Frontend and Backend
This is the standard for professional, scalable apps where the UI and logic are decoupled and communicate via API.
Ideal for - Startups, teams with specialists, and multi-platform apps (Web Mobile).
Pros - Better scalability and easier to swap technologies later.
Cons - Higher initial complexity and setup time.
Option B - Full-Stack Monolith
Everything lives in one codebase using frameworks like Next.js or Tenstack etc.
Ideal for - Solo developers, MVPs, and internal tools.
Pros - Maximum speed to market and simpler deployments.
Cons - Harder to separate or add native mobile apps later.
The Result Is-
If you need to scale and support mobile, separate them. If you need to launch a prototype fast, go full-stack.
