Next.js or a separate SPA? How to choose

How to weigh SEO, performance and team structure when choosing between server rendering and a single-page application.

It is one of the first questions when starting a web application. The answer depends on what the product does.

When is server rendering needed?

Server-prepared HTML is a clear advantage for pages that must be found in search and for visitors on slow devices. Corporate sites, blogs and e-commerce storefronts belong here.

When is an SPA better?

For signed-in, highly interactive admin panels with no search goal, a single-page application can be simpler. If a separate API already exists, hosting gets easier too.

Where is the cost difference?

Server rendering needs a running server and a caching strategy. An SPA can be deployed statically, but the first load can get heavy and data-fetching logic moves to the client.

Can they work together?

Yes. Many products run the marketing site on the server and the application panel mostly on the client. The key is deciding by page type rather than seeking one answer for the whole product.
