## What it is
Inertia.js is a glue framework that lets you build single-page React, Vue, or Svelte apps on top of classic server-side routing and controllers, without building a separate API. It works through client-side and server-side adapters, with official support for Laravel and community adapters for Rails, Django, Phoenix, and more.

## Use cases
- build a single-page app without writing an API
- add React or Vue frontend to a Laravel app
- replace client-side routing with server-side controllers
- build a modern monolith with server-driven navigation
- handle forms and validation without a REST layer
- server-side render an SPA without a separate API backend

## When to choose
- you want SPA interactivity while keeping routing, auth, and validation on the backend
- your stack is Laravel (or Rails/Django/Phoenix) and you don't want to build and maintain an API
- you prefer one codebase and one router over a decoupled frontend/backend split
- you want a batteries-included setup with forms, partial reloads, SSR, and prefetching

## When to avoid
- you need a fully decoupled frontend consuming a public or mobile API
- you need heavy client-side routing, offline support, or complex client-side state
- your backend framework has no Inertia adapter
- you're building a native mobile app or need API-first architecture
