React Server Components vs Client Components: A Decision Guide
When to fetch on the server, when to hydrate in the browser, and how this affects SEO and Time to Interactive.

Server Components reduce JavaScript shipped to browsers by rendering static and data-heavy UI on the server. Client Components handle interactivity. Mixing them wrong negates the benefits.
Default to server
Marketing pages, blog layouts, product catalogues and admin tables that rarely mutate should render on the server. Pass serialisable props only — no functions across the boundary.
Client for interactivity
Forms with instant validation, drag-and-drop, charts with zoom, and anything using browser APIs need "use client". Keep these islands small.
Laravel + Inertia alternative
Not every team needs Next.js. Inertia.js with React gives SPA ergonomics while Laravel owns routing and auth. We use both patterns depending on SEO requirements.
