Next.js and TanStack Start are both full-stack React frameworks that render pages on the server, so either can produce a fast, search-friendly site. Next.js is the safer default for marketing sites and products that a growing team will maintain. TanStack Start suits projects where you want type-safe routing, explicit data loading and a lean Vite setup you control end to end.
I use both in production. I rebuilt procol.ai on Next.js, TypeScript and Tailwind CSS, and this portfolio, mohitgoyal.in, runs on TanStack Start. Here is how I decide between them.
What is the difference between Next.js and TanStack Start?
The short version: Next.js is a complete, opinionated platform with conventions for almost everything. TanStack Start is a thinner layer on top of TanStack Router and Vite, where routing and data loading are typed end to end and you assemble more of the rest yourself.
| Factor | Next.js | TanStack Start |
|---|---|---|
| Built on | Its own compiler and server, with the App Router and React Server Components | TanStack Router and Vite |
| Routing | File-based folders, layouts and route groups | File-based routes with typed paths, params and search params |
| Data loading | Server Components fetch data inside the component tree | Route loaders run before the route renders, and their return type flows to the component |
| Server code | Route handlers and server actions | Server routes and server functions |
| Metadata | Metadata API and generateMetadata | A head function per route |
| Images and fonts | Built in, with next/image and next/font | Bring your own approach |
| Hosting | Least setup on Vercel, runs elsewhere with adapters | Vite build that targets Node or edge platforms |
| Hiring | Large pool of developers who know it | Smaller pool, though any React developer picks it up |
When should you choose Next.js?
When the site is mainly marketing content and the people maintaining it will change over time. That was the situation at Procol. The marketing team needed to ship landing pages quickly, the site had to protect search visibility the company had already earned, and other developers would work on it after me.
Next.js gave server rendering and route-level code splitting out of the box, which is the shortest path to good Core Web Vitals on a content-heavy site. Its conventions mean a new developer finds things where they expect them. The Procol Nexus 2026 event page shipped from the same codebase and inherited the hosting, analytics and SEO setup without extra work. That kind of reuse is where a well-known, opinionated framework pays off.
Choose Next.js when:
- The site is mostly pages, posts and campaign landing pages.
- You want built-in image and font handling.
- Someone else will maintain it, so hiring and documentation matter.
- You are happy to host on Vercel, or willing to configure an adapter elsewhere.
When should you choose TanStack Start?
When the project behaves more like an app and you want the data flow to be explicit. I picked TanStack Start for this portfolio because I wanted server-side rendering with type-safe routing. That keeps every project page indexable and makes the data loading obvious: each route's loader fetches what the page needs before it renders, and TypeScript knows the shape of that data in the component.
The site mixes several kinds of content. Projects come from a Firestore profile, case studies and posts are markdown files in the repo, and the AI chat streams replies from a server route that calls the Claude API. Having all of that in one Vite project, with typed routes between them, kept it simple to reason about.
Choose TanStack Start when:
- You want typed links, params and search params across the whole app.
- Data loading per route matters more than built-in image tooling.
- You prefer Vite and want to choose your own hosting target.
- One developer or a small team that knows the codebase will maintain it.
How do I decide on a real project?
I ask three questions, in this order.
Most client marketing sites land on Next.js, because the maintenance question decides it. Tools, dashboards and personal products are where TanStack Start earns its place. If you are not sure, the free Tech Stack Advisor takes your project, your team and your priority and returns a recommendation with reasons and trade-offs.
Is one faster than the other?
Not in a way that should decide your project. Both send complete HTML from the server, both split code by route, and both can be served from a CDN or an edge network. Speed comes from what you put on the page: image weight, font loading, third-party scripts and how much JavaScript the browser has to run. A heavy page is slow on either framework, and a lean page is fast on either.
What differs is how much you get for free. Next.js handles responsive images and self-hosted fonts for you. On TanStack Start I serve images from a dedicated assets subdomain and handle fonts myself, which is more work but not hard.
Does the choice change your SEO?
The framework only gets you server-rendered HTML. Everything else is the same work on both:
- A unique title, description and canonical URL per page.
- JSON-LD structured data. On this site each page carries its own, such as Person, CreativeWork, BreadcrumbList and ItemList, and posts carry BlogPosting.
- A generated sitemap and an
llms.txtfile, both built from the same content the pages render. - 301 redirects for old URLs. When I moved this portfolio off WordPress, every legacy URL from Search Console got a redirect.
My technical SEO checklist for Next.js covers that layer in full, and almost all of it applies to TanStack Start too.
What would I pick today?
For a client marketing site, a SaaS site or a store frontend: Next.js. It is the choice the next developer will thank you for. For a product with app-like data flow that I or a small team will own: TanStack Start.
I build on both through my Next.js and React websites service. If you are choosing for a specific project, send me a few lines about it and I will tell you which I would use and why.
