Comparing Next.js and React directly is a slightly odd framing: Next.js is a framework built on React. The useful question is whether a plain React single-page app, or a framework around React, is the better fit for what you are building.
What a framework adds
Rendering choices. A client-only React app ships a mostly empty HTML page and builds the UI in the browser. Next.js can render on the server, at build time, or in the client, per route. That matters for SEO and for first-load speed.
Routing and data loading. File-based routing, layouts, and server-side data fetching come built in, so teams spend less time assembling and maintaining a custom stack.
Deployment and caching. Image optimisation, font handling, and caching primitives are part of the platform instead of separate projects.
When plain React is enough
- Internal tools behind a login, where SEO is irrelevant.
- Highly interactive dashboards where nearly everything is client state.
- Apps embedded in a larger host application.
When Next.js is the better default
- Public-facing products that need to be found in search.
- Products where load time affects conversion.
- Teams that want one convention for routing, data, and rendering across many engineers.
What we do
For most public-facing products we start with Next.js, use server components for data-heavy views, and keep the client bundle small for the interactive parts. On a booking-platform rebuild, that shift was the difference between a 4.1 second median load and 900 milliseconds. See the full case study.
