Next.js vs Traditional React: When to Use What

Clients ask me this all the time: "Do I need Next.js or is plain React fine?" Short answer: it depends on what you're building. Here's how I think about it.

Go with Next.js When...

• SEO matters. Server-side rendering gives search engines fully rendered pages. If you need to rank on Google, this is huge.
• Performance is a priority. Automatic code splitting, image optimization, edge functions. Next.js handles a ton of this out of the box.
• You want full-stack in one repo. API routes, server actions, middleware. No need for a separate backend for many use cases.
• Your site is content-heavy. Blogs, portfolios, marketing pages. Static generation makes these insanely fast.

Stick with Vite + React When...

• You're building internal tools. Admin dashboards and internal apps don't need SEO. A simpler setup gets you moving faster.
• It's a single-page app. If the whole app lives behind a login, client-side rendering works fine.
• You're prototyping. Speed of setup matters more than long-term architecture when you're validating an idea.

What I Default To

Nine times out of ten, I reach for Next.js on client projects. The performance wins, SEO benefits, and full-stack capabilities make it worth the slightly steeper learning curve. The ecosystem is mature and the community is massive, which means fewer surprises in production.
