This is the most common technical question we hear from founders starting a new project: "Should I use Next.js or Vite?" The answer is not about which framework is better. They are both excellent. The answer is about what you are building.
The one-minute version
Next.js when your product needs to be found by Google. Vite when it does not.
That single question, "does this need SEO?", resolves about 80% of the decisions. Marketing sites, e-commerce stores, content platforms, and any public-facing product where organic search traffic matters: Next.js. Internal tools, dashboards, admin panels, and apps behind a login: Vite.
The remaining 20% is nuance. Here is the nuance.
When Next.js wins
Server-side rendering (SSR) and static generation. Next.js can render pages on the server before sending them to the browser. This means search engines see fully rendered content, social media previews work correctly, and the initial page load is fast because the HTML is ready before JavaScript runs.
Full-stack in one framework. Next.js includes API routes, middleware, and server components. For a small team or solo founder, having the frontend and backend in one project reduces operational complexity. One deployment, one repository, one mental model.
The static export sweet spot. This is what we use for most Kaizen projects, including this very website. Next.js static export gives you the framework benefits (file-based routing, image optimization, TypeScript integration) without running a server. The output is plain HTML and JavaScript files that deploy to any CDN for pennies.
You get the developer experience of Next.js with the deployment simplicity and performance of a static site. For marketing sites, documentation, and any content that does not change per-user, this is the best of both worlds.
When Vite wins
Pure client-side applications. If your app lives entirely behind a login screen, SEO is irrelevant. Vite gives you a faster development server, simpler configuration, and no server-side complexity to think about.
Development speed.Vite's hot module replacement is nearly instant, even in large projects. Next.js has improved significantly with Turbopack, but Vite's dev experience is still the benchmark. When you are iterating on UI quickly, every millisecond of HMR latency adds up over a day of development.
Maximum flexibility. Vite is a build tool, not a framework. It does not impose opinions about routing, data fetching, or project structure. If you have strong opinions about these things (or your team already has established patterns), Vite stays out of your way.
Library-agnostic. While we primarily use Vite with React, it also works with Vue, Svelte, Solid, and others. If your team works across frameworks, Vite is a consistent build layer.
The decision matrix
Here is how we decide for actual projects:
- Marketing site or landing page: Next.js static export. SEO matters, performance matters, and the static export deploys anywhere.
- SaaS dashboard: Vite + React. Behind a login, no SEO need. Fast dev iteration is more valuable than SSR.
- E-commerce store: Next.js with SSR. Product pages need Google indexing and social previews. Dynamic pricing and inventory require server-side logic.
- Internal business tool: Vite + React. Maximum flexibility, fastest iteration speed, zero SEO consideration.
- Content platform or blog: Next.js static export or SSR depending on volume. Content needs search indexing.
- Mobile-first app (PWA): Vite. Lighter bundle, simpler service worker integration, no server dependency.
What about the alternatives?
Remix: Excellent framework with great data loading patterns. The trade-off is a smaller ecosystem and fewer deployment options compared to Next.js. We recommend it for apps with complex form handling and nested layouts. For most MVPs, Next.js covers the same ground with more community support.
Astro: Perfect for content-heavy sites with minimal interactivity. If your site is 90% static content with a few interactive islands, Astro gives you the best performance. For applications with significant client-side interactivity, stick with Next.js or Vite.
SvelteKit: Svelte produces smaller bundles and has a devoted community. The trade-off is a smaller talent pool if you need to hire, and fewer ready-made component libraries. Great technology, harder to staff.
None of these are wrong choices. But when clients ask us "what should I use?" and they need a decision, not a comparison chart, we give them Next.js or Vite because the ecosystem support, hiring pool, and community resources make the long-term bet safer.
Our defaults
At Kaizen, our default stack for most projects is Next.js with static export, TypeScript, and Tailwind. This covers marketing sites, landing pages, content sites, and even some applications where the dynamic content is loaded client-side after the initial render.
For pure client-side applications (dashboards, admin tools, internal apps), we switch to Vite + React + Tailwind. Same styling system, same component patterns, different build tool.
Both choices are informed by the same principle: pick the simplest tool that solves the problem. Adding server-side rendering to an internal dashboard adds complexity for zero benefit. Skipping SSR on a marketing site costs you organic traffic. Match the tool to the job.
The choice that does not matter
Here is the uncomfortable truth: for most MVPs, the framework choice barely affects success. Products fail because they solve the wrong problem, not because they picked Vite instead of Next.js. Both frameworks are mature, well-supported, and capable of building excellent software.
If you have been deliberating for more than a day, stop. Pick the one that matches the heuristic at the top of this article (SEO needed? Next.js. No SEO? Vite), and start building. The decision that matters is what you build, not what you build it with.
