Next.js App Router SaaS projects use a pragmatic folder structure that divides code into `app/`, `features/`, and `shared/` directories. This organization defines clear boundaries for routing, domain logic, and shared utilities to reduce cognitive overhead and improve maintainability.

To separate server and client logic in a Next.js SaaS application, place server-only code within a dedicated `server/` directory. This establishes clear server/client boundaries, keeping server actions, schemas, and types secure while maintaining indie-friendly project maintainability.

Define feature boundaries in a Next.js SaaS project by grouping domain-specific logic within `features/<feature>/` directories. This feature-based organization encapsulates related hooks, utils, and types, preventing code entanglement and promoting rapid indie-friendly development.

Place server actions and hooks in a Next.js SaaS folder structure by utilizing dedicated sub-directories. Server actions go within the feature's `server/` directory, while hooks reside alongside schemas and types to maintain a clear separation of concerns.

Yes, you can use this Next.js folder structure for refactoring an existing SaaS project to establish a clean, scalable codebase. It provides a pragmatic code placement strategy that updates file organization across app, features, and shared directories for low maintenance.

Next.js SaaS code becomes hard to maintain as features grow due to unclear folder responsibilities and tangled server/client logic. Applying a feature-based organization with distinct `app/`, `features/`, and `shared/` directories solves this by reducing cognitive overhead and improving maintainability.
